If you&#39;re using .NET 3.5 or higher, it&#39;s easy using LINQ to Objects:

    stringCutted = myString.Split(&#39;/&#39;).Last();

Note that [`Last()`][1] (without a predicate) is optimized for the case where the source implements `IList&lt;T&gt;` (as a single-dimensional array does) so this *won&#39;t* iterate over the whole array to find the last element. On the other hand, that optimization is undocumented...


  [1]: http://msdn.microsoft.com/en-us/library/bb358775.aspx

    stringCutted=myString.Split(&quot;/&quot;).Last()

But, just FYI, if you&#39;re trying to get a filename from a path, this works heaps better:

    var fileName=System.IO.Path.GetFileName(&quot;C:\\some\path\and\filename.txt&quot;); 
    // yields: filename.txt

Since you want a solution that returns the last element directly, quickly, without store the splitted array, i think this may be useful:

    stringCutted = myString.Substring(myString.LastIndexOf(&quot;/&quot;)+1);



Use LINQ

    &quot;t/e/s/t&quot;.Split(&quot;/&quot;).Last();

For using this code, I skip last element from the `Url` link.

    string url = Request.Url.ToString().Substring(0, Request.Url.ToString().LastIndexOf(&#39;/&#39;));

**For Addition:**

When string format like `&#39;a/b/c/d&#39;` then 

    yourstring.Split(&quot;/&quot;).Last();

When string format like `\head_display\27_[Item A]\head_image\original_image\1_Item A.png`

    yourstring.Split(&quot;\\&quot;).Last();

first &#39;\\&#39; actually to skip second &#39;\\&#39;

I want to create a column `element_type` in a table (called `discussion`) that allows the text values &quot;lesson&quot; or &quot;quiz&quot; but will generate an error if any other value is inserted into that column.

I understand that I could create a separate table called `element_types` with columns `element_id` (primary key, int) and `element_type` (unique, text) and create a foreign key `foreign_element_id` in the table `discussion` referencing `element_types`&#39;s column `element_id`.  Or alternatively, I could forget `element_id` altogether and just set `element_type` as the primary key.  But I want to avoid creating a new table.

Is there a more straightforward way to restrict possible values in a column without creating a new table?

In Postgres, how do you restrict possible values for a particular column?

I have this code :

    stringCutted = myString.Split(&quot;/&quot;). // ???

and I&#39;d like to store in `stringCutted` the last element of the `string[]` after the split, directly, quickly, without storing the splitted array in a variable and access to that element with `array[array.length]`.

Is this possible in C#?

Select last element quickly after a .Split()

I have this code :
<pre><code class="hljs language-ini">stringCutted = myString.Split("/"). // ???
</code></pre>
and I'd like to store in <code>stringCutted</code> the last element of the <code>string[]</code> after the split, directly, quickly, without storing the splitted array in a variable and access to that element with <code>array[array.length]</code>.
Is this possible in C#?

Imagine I have defined the following Enum:

    public enum Status : byte
    {
        Inactive = 1,
        Active = 2,
    }

What&#39;s the best practice to use enum? Should it start with `1` like the above example or start with `0` (without the explicit values) like this:

    public enum Status : byte
    {
        Inactive,
        Active
    }

Should an Enum start with a 0 or a 1?

I am initiating an HttpWebRequest and then retrieving it&#39;s response.  Occasionally, I get a 500 (or at least 5##) error, but no description.  I have control over both endpoints and would like the receiving end to get a little bit more information.  For example, I would like to pass the exception message from server to client.  Is this possible using HttpWebRequest and HttpWebResponse?

Code:

    try
    {
    	HttpWebRequest webRequest = HttpWebRequest.Create(URL) as HttpWebRequest;
    	webRequest.Method = WebRequestMethods.Http.Get;
    	webRequest.Credentials = new NetworkCredential(Username, Password);
    	webRequest.ContentType = &quot;application/x-www-form-urlencoded&quot;;
    	using(HttpWebResponse response = webRequest.GetResponse() as HttpWebResponse)
    	{
    		if(response.StatusCode == HttpStatusCode.OK)
    		{
    			// Do stuff with response.GetResponseStream();
    		}
    	}
    }
    catch(Exception ex)
    {
    	ShowError(ex);
        // if the server returns a 500 error than the webRequest.GetResponse() method
        // throws an exception and all I get is &quot;The remote server returned an error: (500).&quot;
    }

Any help with this would be much appreciated.

How do I specify the argument passed to `orderby` using a value I take as a parameter?

Ex:

    List&lt;Student&gt; existingStudends = new List&lt;Student&gt;{ new Student {...}, new Student {...}}

Currently implementation:

    List&lt;Student&gt; orderbyAddress = existingStudends.OrderBy(c =&gt; c.Address).ToList();

Instead of `c.Address`, how can I take that as a parameter?

Example 

     string param = &quot;City&quot;;
     List&lt;Student&gt; orderbyAddress = existingStudends.OrderByDescending(c =&gt; param).ToList();

Is there a better way to replace strings?

I am surprised that Replace does not take in a character array or string array.  I guess that I could write my own extension but I was curious if there is a better built in way to do the following?  Notice the last Replace is a string not a character.

    myString.Replace(&#39;;&#39;, &#39;\n&#39;).Replace(&#39;,&#39;, &#39;\n&#39;).Replace(&#39;\r&#39;, &#39;\n&#39;).Replace(&#39;\t&#39;, &#39;\n&#39;).Replace(&#39; &#39;, &#39;\n&#39;).Replace(&quot;\n\n&quot;, &quot;\n&quot;);

I&#39;m doing a loop through few input elements of &#39;checkbox&#39; type. After that, I&#39;m adding values and checked attributes to an array. This is my code:

    var stuff = {};
    $(&#39;form input[type=checkbox]&#39;).each(function() {
        stuff[$(this).attr(&#39;value&#39;)] = $(this).attr(&#39;checked&#39;);
    });

This works fine, but I&#39;m just wondering if I can do the exact same thing with .push() method in Jquery?

I&#39;ve tried something like this but it doesn&#39;t work:

    stuff.push( {$(this).attr(&#39;value&#39;):$(this).attr(&#39;checked&#39;)} );

**Edit:**

I was trying to use .push() method on Object, but .push() is actually just a method of Array Object.

I have an array of e-mails (it can be just 1 email, or 100 emails), and I need to send the array with an ajax request (that I know how to do), but I can only send an array that has 10 or less e-mails in it. So if there is an original array of 20 e-mails I will need to split them up into 2 arrays of 10 each. or if there are 15 e-mails in the original array, then 1 array of 10, and another array of 5. I&#39;m using jQuery, what would be the best way to do this?

Check whether a string contains a substring

Lets say I have a string:

    char theString[] = &quot;你们好āa&quot;;

Given that my encoding is utf-8, this string is 12 bytes long (the three hanzi characters are three bytes each, the latin character with the macron is two bytes, and the &#39;a&#39; is one byte:

    strlen(theString) == 12

How can I count the number of characters? How can i do the equivalent of subscripting so that:

    theString[3] == &quot;好&quot;

How can I slice, and cat such strings?

Is there an NOT operator in Regexes?
Like in that string : `&quot;(2001) (asdf) (dasd1123_asd 21.01.2011 zqge)(dzqge) name (20019)&quot;`

I want to delete all `$[0-9a-zA-z _\.\-:]*$` but not the one where it is a year: `(2001)`.

So what the regex should return must be: `(2001) name`.

NOTE: something like `$(?![\d]){4}[0-9a-zA-z _\.\-:]*$` does not work for me (the `(20019)` somehow also matches...)

splitting a string based on multiple char delimiters

I want to split a text with comma `,` not space ` ` in `for foo in list`. Suppose I have a CSV file `CSV_File` with following text inside it:

    ...

I used following code to split it into several words:

    for word in $(cat CSV_File | sed -n 1&#39;p&#39; | tr &#39;,&#39; &#39;\n&#39;)
    do echo $word
    done

It prints:

    Hello
    World
    Questions
    Answers
    bash
    shell
    script


But I want it to split the text by commas not spaces:

How to split a list by comma not space

I was wondering if it was possible to split a file into equal parts (*edit:* = all equal except for the last), without breaking the line? Using the split command in Unix, lines may be broken in half. Is there a way to, say, split up a file in 5 equal parts, but have it still only consist of whole lines (it&#39;s no problem if one of the files is a little larger or smaller)? I know I could just calculate the number of lines, but I have to do this for a lot of files in a bash script. Many thanks!
