Escape them with backslashes.

    &quot;I want to learn \&quot;C#\&quot;&quot;

As well as escaping quotes with backslashes, also see SO question [2911073][1] which explains how you could alternatively use double-quoting in a @-prefixed string:

    string msg = @&quot;I want to learn &quot;&quot;c#&quot;&quot;&quot;;



  [1]: https://stackoverflow.com/questions/2911073/how-can-i-put-quotes-in-a-string &quot;2911073&quot;

I use:

    var value = &quot;&#39;Field1&#39;,&#39;Field2&#39;,&#39;Field3&#39;&quot;.Replace(&quot;&#39;&quot;, &quot;\&quot;&quot;); 

as opposed to the equivalent

    var value = &quot;\&quot;Field1\&quot;,\&quot;Field2\&quot;,\&quot;Field3\&quot;&quot;;

Because the former has far less noise than the latter, making it easier to see typo&#39;s etc.  

I use it a lot in unit tests.



    string str = @&quot;&quot;&quot;Hi, &quot;&quot; I am programmer&quot;;

OUTPUT - &quot;Hi, &quot; I am programmer



Use escape characters for example this code:

    var message = &quot;I want to learn \&quot;c#\&quot;&quot;;
    Console.WriteLine(message);

will output:

&gt; I want to learn &quot;c#&quot;

You can also declare a constant and use it each time. neat and avoids confusion:

    const string myStrQuote = &quot;\&quot;&quot;;

The Code:

`string myString = &quot;Hello &quot; + ((char)34) + &quot; World.&quot; + ((char)34);`

Output will be:

&gt; Hello &quot;World.&quot;

I basically want to do this:

    switch($someString.ToLower())
    {
        &quot;y&quot;, &quot;yes&quot; { &quot;You entered Yes.&quot; }
        default { &quot;You entered No.&quot; }
    }


What&#39;s the PowerShell syntax for multiple values in a switch statement?

Using SQLite3 in Python, I am trying to store a compressed version of a snippet of UTF-8 HTML code.

Code looks like this:

    ...
    c = connection.cursor()
    c.execute(&#39;create table blah (cid integer primary key,html blob)&#39;)
    ...
    c.execute(&#39;insert or ignore into blah values (?, ?)&#39;,(cid, zlib.compress(html)))

At which point at get the error:

    sqlite3.ProgrammingError: You must not use 8-bit bytestrings unless you use a text_factory that can interpret 8-bit bytestrings (like text_factory = str). It is highly recommended that you instead just switch your application to Unicode strings.

If I use &#39;text&#39; rather than &#39;blob&#39; and don&#39;t compress the HTML snippet, it works all fine (db is to large though). When I use &#39;blob&#39; and compress via Python zlib library, I get the above error message. I looked around but couldn&#39;t find a simple answer for this one.

I&#39;m working with C#, Framework 3.5 (VS 2008).

I&#39;m using the `ConfigurationManager` to load a config (not the default app.config file) into a Configuration object.

Using the Configuration class, I was able to get a `ConfigurationSection`, but I could not find a way to get the values of that section.

In the config, the `ConfigurationSection` is of type `System.Configuration.NameValueSectionHandler`.


For what it worth, when I used the method `GetSection` of the `ConfigurationManager` (works only when it was on my default app.config file), I received an object type, that I could cast into collection of pairs of key-value, and I just received the value like a Dictionary. I could not do such cast when I received `ConfigurationSection` class from the Configuration class however.

EDIT:
Example of the config file:

    &lt;configuration&gt;
      &lt;configSections&gt;
        &lt;section name=&quot;MyParams&quot; 
                 type=&quot;System.Configuration.NameValueSectionHandler&quot; /&gt;
      &lt;/configSections&gt;
    
      &lt;MyParams&gt;
        &lt;add key=&quot;FirstParam&quot; value=&quot;One&quot;/&gt;
        &lt;add key=&quot;SecondParam&quot; value=&quot;Two&quot;/&gt;
      &lt;/MyParams&gt;
    &lt;/configuration&gt;



Example of the way i was able to use it when it was on app.config (the &quot;GetSection&quot; method is for the default app.config only):

    NameValueCollection myParamsCollection =
                 (NameValueCollection)ConfigurationManager.GetSection(&quot;MyParams&quot;);
    
    Console.WriteLine(myParamsCollection[&quot;FirstParam&quot;]);
    Console.WriteLine(myParamsCollection[&quot;SecondParam&quot;]);

In Java, the [`throws`][1] keyword allows for a method to declare that it will not handle an exception on its own, but rather throw it to the calling method.

Is there a similar keyword/attribute in C#?

If there is no equivalent, how can you accomplish the same (or a similar) effect?

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.

I am having a problem converting a datetime which is in string format but I am not able to convert it using `&quot;yyyyMMdd&quot;` format.

My code is:

    string tpoc = refSubClaim.BenefitsFolder.BenefitFolderIdNumber.ToString();
    string[] tpocinfo = Regex.Split(tpoc,&quot;;&quot;);
                                    
    for (int i = 0; i &lt; tpocinfo.Length; i++)
    {

            {
                string[] tpoc2 = Regex.Split(tpocinfo[0], &quot;,&quot;);
                claimantAuxillaryRecord.TPOCDate2 = tpoc2[0].ToString();
                claimantAuxillaryRecord.TPOCAmount2 = Convert.ToDecimal(tpoc2[1]);
                claimantAuxillaryRecord.FundingDelayedBeyondTPOCStartDate2 = tpoc2[2].ToString();

I have a shopping cart that displays product options in a dropdown menu and if they select &quot;yes&quot;, I want to make some other fields on the page visible. 

The problem is that the shopping cart also includes the price modifier in the text, which can be different for each product. The following code works:

    $(document).ready(function() {
        $(&#39;select[id=&quot;Engraving&quot;]&#39;).change(function() {
            var str = $(&#39;select[id=&quot;Engraving&quot;] option:selected&#39;).text();
            if (str == &quot;Yes (+ $6.95)&quot;) {
                $(&#39;.engraving&#39;).show();
            } else {
                $(&#39;.engraving&#39;).hide();
            }
        });
    });

However I would rather use something like this, which doesn&#39;t work:

    $(document).ready(function() {
        $(&#39;select[id=&quot;Engraving&quot;]&#39;).change(function() {
            var str = $(&#39;select[id=&quot;Engraving&quot;] option:selected&#39;).text();
            if (str *= &quot;Yes&quot;) {
                $(&#39;.engraving&#39;).show();
            } else {
                $(&#39;.engraving&#39;).hide();
            }
        });
    });

I only want to perform the action if the selected option contains the word &quot;Yes&quot;, and would ignore the price modifier.

How do I check if string contains substring?

Is there any function in java like toString() to print a String array?

This is a silly question but I want to know if there is any other way than writing a for loop.

Thanks.

I have a string, `&quot;004-034556&quot;`, that I want to split into two strings:

    string1=&quot;004&quot;;

That means the first string will contain the characters before `&#39;-&#39;`, and the second string will contain the characters after `&#39;-&#39;`. I also want to check if the string has `&#39;-&#39;` in it. If not, I will throw an exception. How can I do this?

I have variable like:

My need is that whatever string is passed to it I have to display the content inside a *div* with in a double quotes. So I have written something like:

    ...
    ...
    &lt;div&gt;&quot;+ title +@&quot;&lt;/div&gt;
    ...
    ...

But how can I add the double quotes here? So that it will display like:

How can I add double quotes to a string that is inside a variable?

According to Crockford&#39;s [json.org][1], a JSON *object* is made up of *members*, which is made up of *pairs*.

Every pair is made of a *string* and a *value*, with a *string* being defined as:

&gt; A string is a sequence of zero or more
&gt; Unicode characters, wrapped in double
&gt; quotes, using backslash escapes. A
&gt; character is represented as a single
&gt; character string. A string is very
&gt; much like a C or Java string.

But in practice most programmers don&#39;t even know that a JSON key should be surrounded by double quotes, because most browsers don&#39;t require the use of double quotes.

Does it make any sense to bother surrounding your JSON in double quotes?

Valid Example:

    {
      &quot;keyName&quot; : 34
    }

As opposed to the invalid:

    {
       keyName : 34
    }

Simple question, is there any way to omit the double quote in PostgreSQL?

Here is an example, giving `select * from A;`, I will retrieve `ERROR:  relation &quot;a&quot; does not exist`, and I would have to give `select * from &quot;A&quot;;` to get the real result.

Is there any way not to do the second and instead do the first on PostgreSQL?

Is there a specific time when I should use `&quot;&quot;` vs `&#39;&#39;`?

I&#39;ve been using single quotes most of the time because it&#39;s easier to type but I&#39;m not sure if I should.


e.g. `get &#39;user/new&#39;` vs. `get &quot;user/new&quot;`
