You are correct, it only works in server controls. You&#39;ve got these basic options:

Change to `HyperLink` to run as a [Web Control][1]:

    &lt;asp:HyperLink NavigateUrl=&quot;~/BusinessOrderInfo/page.aspx&quot; Text=&quot;Whatever&quot; runat=&quot;server&quot; /&gt;

Or, run the anchor on the server side as an [HTML Control][2]: 

    &lt;a href=&quot;~/BusinessOrderInfo/page.aspx&quot; runat=&quot;server&quot; &gt;

Or, use `Page.ResolveUrl`:

    &lt;a href=&quot;&lt;%= Page.ResolveUrl(&quot;~/BusinessOrderInfo/page.aspx&quot;) %&gt;&quot;&gt;...&lt;/a&gt;

HTML controls can be turned into server controls by adding the runat=&quot;server&quot; attribute.

    &lt;a href=&quot;~/BusinessOrderInfo/page.aspx&quot; runat=&quot;server&quot;&gt;


The tilde refers to the application root directory, and will be translated correctly in control properties such as NavigateUrl. 

My understanding is that if you use it in plain-HTML tags, it will not be translated by ASP.Net.

If you remove tilde and use forward slash only you will achieve the same result, i.e. pointing to the root folder on the current domain:

    &lt;a href=&quot;/BusinessOrderInfo/page.aspx&quot; &gt;

This function can also be used to resolve paths for non server elements

I would like a method that takes a `List&lt;T&gt;` where `T` implements `Comparable` and returns `true` or `false` depending on whether the list is sorted or not.

What is the best way to implement this in Java?  It&#39;s obvious that generics and wildcards are meant to be able to handle such things easily, but I&#39;m getting all tangled up.

It would also be nice to have an analogous method to check if the list is in reverse order.

i&#39;m working on an asp.net app, the following link works in IE but not in FF.

    &lt;a href=&quot;~/BusinessOrderInfo/page.aspx&quot; &gt;

Isn&#39;t the tilde something that can only be used in asp.net server controls.  Where it will be replaced by an actual path?

Is it possible to use the tilde in an anchor tag? If so what does it mean?

When I&#39;m at the root, the link works

    www.myserver.com/default.aspx, click the link, ok!

    www.myserver.com/otherpart/default.aspx, click the link, not ok!

The link generated by ASP.NET is:

    www.myserver.com/otherpart/~BusinessOrderInfo/page.aspx

Is this by design?

I am finally playing catchup with everything new that has been added in to the .NET 3.5/4.0 Frameworks. The last few days I have been working with CodeContracts and I am really trying hard to like them. I am curious what other people think of the implementation of CodeContracts in C#? Specifically, how are people organizing things like Contract classes for interfaces, contract methods for Contract Invariants etc?

I like the validation that contracts provide, at first glance they look great. With a few simple lines I can get some nice build checking before I even run my code. Unfortunately, I am having a hard time getting over the feeling that the way that code contracts are implement in C#, they are cluttering up my code more than they are documenting contracts. And to take full advantage of contracts, I am littering my code with assumptions and asserts etc (which I know some will say is a good thing); but as some of my examples below will show, it turns a single simple line in to 4 or 5 lines, and doesn&#39;t really add sufficient value in my opinion over alternative approaches (i.e., asserts, exceptions etc).

Currently, my greatest frustrations are:

Interface Contracts:
  

    [ContractClass(typeof(IInterfaceContract))]
      public interface IInterface
      {
        Object Method(Object arg);
      }
    
      [ContractClassFor(typeof(IInterface))]
      internal abstract class IInterfaceContract
      {
        private IInterfaceContract() { }
    
        Object IInterface.Method(Object arg)
        {
          Contract.Requires(arg != null);
          Contract.Ensures(Contract.Result&lt;Object&gt;() != null);
          return default(Object);
        }
      }

This feels like such a cludge to me, I wish there was a cleaner way to document requirements, either via attributes or some form of built in language support. The fact that I have to implement an abstract class that implements my interface, just so I can specify the contract seems tedious at best.

Code Bloat:

    typeof(Action&lt;&gt;).MakeGenericType(typeof(Object);

Requires several assumptions just to verify information that is readily available. I appreciate that all the analyzer knows is that it is operating on Type and thus must work on that limited knowledge, but it still frustrates me that a single line of code requires me to re-write as

    var genericAction = typeof(Action&lt;&gt;);
         
    Contract.Assume(genericAction.IsGenericType);
    Contract.Assume(genericAction.GetGenericArguments().Length == 1);
    
    genericAction.MakeGenericType(typeof(Object));

Just to keep things documented (yes I know I can use ContractVerificationAttribute to turn this off for a method/class etc, or SuppressMessageAttribbute to target specific messages, but that seems to defeat the purpose as your code would quickly become littered with suppressions etc. 

In addition, taking a case like

      public class MyClass
        : IInterface
      {
        private readonly Object _obj;
    
        public Object Property
        {
          get
          {
            Contract.Ensures(Contract.Result&lt;Object&gt;() != null);
            return _obj;
          }
        }
    
        public MyClass(Object obj)
        {
          Contract.Requires(obj != null);
    
          _obj = obj;
        }
      }

obj is required to be not null, and is set to a readonly field that cannot be changed, yet I am still required to add a &quot;markup&quot; method to my class so that my property requirement to not return null can be proven:

    [ContractInvariantMethod]
    private void ObjectInvariant()
    {
      Contract.Invariant(_obj != null);
    }

There is more, but I figured I have probably ranted enough, and I would really appreciate the insight of people much smarter than me to help me &quot;like&quot; Code Contracts and make this feeling of code clutter go away. Any insight on how to better structure code, workaround wonkiness issues etc would be greatly appreciated.

Thanks!






Really trying to like CodeContracts in C#

How can I convert an `int` datatype into a `string` datatype in C#?

Convert int to string?

I&#39;m trying to make my integration tests more idempotent.  One idea was to execute rollback after every test, the other idea was to some how programatically parse the text, similar to the green check box in Query Analyzer or SSMS.

How do I get SQL Server to parse my command without running it using ADO.NET?

**UPDATE:** 
This is what finally worked as desired:

    using (DbCommand executeOnly = Factory.DbCommand())
    {
        executeOnly.Connection = command.Connection;
        executeOnly.CommandType = CommandType.Text;
        executeOnly.CommandText = &quot;SET NOEXEC ON;&quot; + sqlCommand;
        executeOnly.Connection.Open();
        executeOnly.ExecuteNonQuery();
    }
    //set more properties of command.
    command.Execute();

For inexplicable reasons, &quot;`SET PARSEONLY ON`&quot; only worked in Query Analyzer.  I couldn&#39;t set this on an ADO.NET connection.  It is just as well because `PARSEONLY` seems to catch only syntax errors, which isn&#39;t a common error.  `SET NOEXEC ON` will catch a wider varieties of errors, such as a view that references a missing table or column or a missing parameter in a stored procedure.

How can I programmatically check (parse) the validity of a TSQL statement?

Is it possible to use a regular expression to detect anything that is NOT an &quot;empty string&quot; like this:

    string s1 = &quot;&quot;;
    string s2 = &quot; &quot;;
    string s3 = &quot;  &quot;;
    string s4 = &quot;   &quot;;

etc.

I know I could use trim etc. but I would like to use a regular expression.

regular expression for anything but an empty string

This is driving me crazy.  

I have a rather large project that I am trying to modify.  I noticed earlier that when I typed `DbCommand`, visual studio did not do any syntax highlighting on it, and I am using using `System.Data.Common`.

Even though nothing was highlighted, the project seemed to be running fine in my browser. So I decided to run the debugger to see if things were really working as they should be.

Every time the class that didn&#39;t do the highlighting is called I get the `&quot;the source file is different from when the module was built&quot;` message. 

I cleaned the solution and rebuilt it several times, deleted tmp files, followed all the directions here https://stackoverflow.com/questions/353421/getting-the-source-file-is-different-from-when-the-module-was-built, restarted the web server and still it tells me the source files are different when they clearly are not. 

I cannot test any of the code I have written today because of this.  

 - How can the source be different than the binary when I just complied
   it?   
 - Is there any way to knock some sense into visual studio, or am
   I just missing something?

the source file is different from when the module was built

Visual Studio 2010 has a Publish command that allows you to publish your Web Application Project to a file system location. I&#39;d like to do this on my TeamCity build server, so I need to do it with the solution runner or msbuild. I tried using the Publish target, but I think that might be for ClickOnce:

    msbuild Project.csproj /t:Publish /p:Configuration=Deploy

I basically want to do exactly what a web deployment project does, but without the add-in. I need it to compile the WAP, remove any files unnecessary for execution, perform any [web.config transformations][1], and copy the output to a specified location.

**My Solution**, based on Jeff Siver&#39;s answer

    &lt;Target Name=&quot;Deploy&quot;&gt;
        &lt;MSBuild Projects=&quot;$(SolutionFile)&quot; 
                 Properties=&quot;Configuration=$(Configuration);DeployOnBuild=true;DeployTarget=Package&quot; 
                 ContinueOnError=&quot;false&quot; /&gt;
        &lt;Exec Command=&quot;&amp;quot;$(ProjectPath)\obj\$(Configuration)\Package\$(ProjectName).deploy.cmd&amp;quot; /y /m:$(DeployServer) -enableRule:DoNotDeleteRule&quot; 
              ContinueOnError=&quot;false&quot; /&gt;
    &lt;/Target&gt;

.NET vs ASP.NET vs CLR vs ASP

This one has me stumped, I have a strongly typed view that has this loop to generate radiobuttons:

    &lt;% foreach (QuestionAnswer qa in Model.QuestionAnswers)
       { %&gt;
        &lt;%= Html.RadioButtonFor(model =&gt; model.QuestionAnswers[(int)qa.QuestionID - 1].AnswerValue, &quot;Checked&quot; ) %&gt;
        &lt;%= Html.Encode(qa.OptionValue) %&gt;
    &lt;% } %&gt;

It renders fine, but since the names are not the same, you can select more than 1 radiobutton.  How can I group them so only 1 radiobutton can be selected?

Any help would be appreciated!



When using .net MVC RadioButtonFor(), how do you group so only one selection can be made?

I am currently attempting to use Visual Studio 2010 &#39;Publish&#39; and MSDeploy functionality to handle my web deployment needs but have run into a roadblock with regards to customizing the package depending on my build configuration.

I develop in a 32bit environment but need to create a release package for a 64bit environment, so in the &#39;Release&#39; configuration I have a post build event that copies the 64bit version of a third-party dll into the bin directory overwriting the 32bit version.  When I use the &#39;Publish&#39; functionality, even though the correct 64bit dll is being copied to the bin directory, it doesn&#39;t get included in the package.

Is there a way to get the &#39;Publish&#39; to include files that have been copied into the bin directory during a post build event?




How to get Visual Studio &#39;Publish&#39; functionality to include files from post build event?

I am creating cookies with following lines:

    HttpCookie userid = new HttpCookie(&quot;userid&quot;, objUser.id.ToString());
    userid.Expires.AddYears(1);
    Response.Cookies.Add(userid);

Now how can I make it persistent?

If I visit the same page again after closing the browser, I&#39;m unable to get it back.
