I am trying to convert a DataTable to an IEnumerable&lt;T&gt;. Where T is a custom type I created. I know I can do it by creating a `List&lt;T&gt;` but I was thinking if there is a slicker way to do it using IEnumerable. Here is what I have now:

    private IEnumerable&lt;TankReading&gt; ConvertToTankReadings(DataTable dataTable)
    {
        var tankReadings = new List&lt;TankReading&gt;();
        foreach (DataRow row in dataTable.Rows)
        {
            var tankReading = 
                  new TankReading
                  {
                      TankReadingsID = Convert.ToInt32(row[&quot;TRReadingsID&quot;]),
                      TankID = Convert.ToInt32(row[&quot;TankID&quot;]),
                      ReadingDateTime = Convert.ToDateTime(row[&quot;ReadingDateTime&quot;]),
                      ReadingFeet = Convert.ToInt32(row[&quot;ReadingFeet&quot;]),
                      ReadingInches = Convert.ToInt32(row[&quot;ReadingInches&quot;]),
                      MaterialNumber = row[&quot;MaterialNumber&quot;].ToString(),
                      EnteredBy = row[&quot;EnteredBy&quot;].ToString(),
                      ReadingPounds = Convert.ToDecimal(row[&quot;ReadingPounds&quot;]),
                      MaterialID = Convert.ToInt32(row[&quot;MaterialID&quot;]),
                      Submitted = Convert.ToBoolean(row[&quot;Submitted&quot;]),
                  };

            tankReadings.Add(tankReading);
        }
        return tankReadings.AsEnumerable();
    }

The key part being I am creating a `List&lt;T&gt;` then returning it using `AsEnumerable()`.

How do I change the folder of my existing solution file (sln)?

It&#39;s right now inside one of my project&#39;s folder; if I cut the solution file and paste it in the root folder,it doesn&#39;t load any of my projects.

I have this code to loop through an object and get all of its properties through reflection:

    foreach (var propertyInfo in typeof(TBase).GetProperties(BindingFlags.Public | BindingFlags.Instance))
    {
        var oldValue = propertyInfo.GetValue(oldVersion, null);
    }

How can I do a check to only look at properties that have a &quot;Set&quot; on them? (I want to ignore read-only values - just &quot;Get&quot;.)

I am trying to use TryParse to find if the string value is an integer. If the value is an integer then skip foreach loop. Here is my code.

    string strValue = &quot;42 &quot;
    
     if (int.TryParse(trim(strValue) , intVal)) == false
     {
        break;
     }

intVal is a variable of type int?(nullable INT). How can I use Tryparse with nullable int?

I am encountering a problem which is how do I convert input strings like &quot;RED&quot; to the actual Color type `Color.Red` in C#. Is there a good way to do this?

I could think of using a switch statement and cases statement for each color type but I don&#39;t think that is clever enough.



Convert string to Color in C#

I have the following code:

   

    return &quot;[Inserted new &quot; + typeof(T).ToString() + &quot;]&quot;;

But

     typeof(T).ToString()

  returns the full name including namespace

Is there anyway to just get the class name (without any namespace qualifiers?)

We upgraded from .NET 2.0 to .NET 3.5.  A co-worker of mine is getting the following dialog when attempting to run the ASP .NET web project under the debugger in Visual Studio 2008.  He can build fine, but he can&#39;t debug (hence, it&#39;s a run-time issue):

Microsoft Visual Studio

&quot;The Extender Provider failed to return an Extender for this object.  Please correct before proceeding.  (You might rename the current web.config and add a new one.)&quot;

OK

Searching on this error provided one hit that is in French, but Google translated, and the dude deleted his web.config.  Well, my co-worker has a web.config.

Thanks!

Extender Provider failed to return an Extender

How can I achieve this?

    public class GenericClass&lt;T&gt;
    {
        public Type getMyType()
        {
            //How do I return the type of T?
        }
    }

Everything I have tried so far always returns type `Object` rather than the specific type used.

Get generic type of class at runtime

I can&#39;t figure out how to make this work:

    object x = new Int32[7];
    Type t = x.GetType();

    // now forget about x, and just use t from here.
    
    // attempt1 
    object y1 = Activator.CreateInstance(t); // fails with exception
    
    // attempt2
    object y2 = Array.CreateInstance(t, 7);  // creates an array of type Int32[][] ! wrong


What&#39;s the secret sauce?  I can make the second one work if I can get the type of the elements of the array, but I haven&#39;t figured that one out either.

How do I create a C# array using Reflection and only type info?

I have the following class:

    public class Test {
        public static int a = 0;
        public int b = 1;
    }

Is it possible to use reflection to get a list of the static fields only? I&#39;m aware I can get an array of all the fields with `Test.class.getDeclaredFields()`. But it seems there&#39;s no way to determine if a `Field` instance represents a static field or not.

Retrieve only static fields declared in Java class

I have a custom attribute:

    public class MenuItemAttribute : Attribute
    {
    }

and a class with a few methods:

    public class HelloWorld
    {
        [MenuItemAttribute]
        public void Shout()
        {
        }

        [MenuItemAttribute]
        public void Cry()
        {
        }

        public void RunLikeHell()
        {
        }
    }

How can I get only the methods that are decorated with the custom attribute?

So far, I have this:

    string assemblyName = fileInfo.FullName;
    byte[] assemblyBytes = File.ReadAllBytes(assemblyName);
    Assembly assembly = Assembly.Load(assemblyBytes);

    foreach (Type type in assembly.GetTypes())
    {
         System.Attribute[] attributes = System.Attribute.GetCustomAttributes(type);

         foreach (Attribute attribute in attributes)
         {
             if (attribute is MenuItemAttribute)
             {
                 //Get me the method info
                 //MethodInfo[] methods = attribute.GetType().GetMethods();
             }
         }
    }


What I need now is to get the method name, the return type, as well as the parameters it accepts.


Find methods that have custom attribute using reflection

I have a method where I need to resolve the Type of a class. This class exists in another assembly with the namespace similar to:

    MyProject.Domain.Model

I am attempting to perform the following:

    Type.GetType(&quot;MyProject.Domain.Model.&quot; + myClassName);

This works great if the code that is performing this action is in the same assembly as the class whose type I am trying to resolve, however, if my class is in a different assembly, this code fails.

I am sure there is a far better way to accomplish this task, but I have not had a lot of experience with resolving assemblies and traversing namespaces within to resolve the type of the class I am looking for. Any advice or tips to accomplish this task more gracefully?
