How to view the w3wp process by C #?

We need to know which w3wp process is running now when we debug my website in the Visual Studio. As we know, we can use this cmd (% WINDIR %/system32/inetsrv/appcmd list WP)To show the result in the windows2008. but, how to view the w3wp process by C #?
I give the method to you, please look this Code:

Static   Void Main ( String [] ARGs)
{
String Str = Cmdlistwp ();
Console. writeline (STR );
Console. writeline ( " Please press any key to exit! " );
Console. Readline ();
}

Private   Static   String Cmdlistwp ()
{
PROCESS p =   New Process ();
P. startinfo. filename =   " Cmd.exe " ; // Set callProgramName
P. startinfo. useshellexecute =   False ; // Disable shell usage
P. startinfo. redirectstandardinput =   True ; // Redirect standard input
P. startinfo. redirectstandardoutput =   True ; // Redirection standard output
P. startinfo. redirectstandarderror =   True ; // Redirect error output
P. startinfo. createnowindow =   True ; // Do not display the Configuration window

String Output;
P. Start ();
Try
{
P. standardinput. writeline ( " % WINDIR %/system32/inetsrv/appcmd list WP " );
P. standardinput. writeline ( " Exit " );
Output = P. standardoutput. readtoend ();
}
Finally
{
P. Close ();
}

String Result =   String . Empty;
If (Output. indexof ( " WP \ "" )! =-1) // whether a website is started
{
// Regular Expression Extraction
// For example: WP "29308" <applicationpool: profile3.csdn.net>
String Pattern =   " WP \ " \ D + \ " . + " ;
List < String > List =   New List < String > ();
RegEx =   New RegEx (pattern );
If (RegEx. ismatch (output ))
{
Matchcollection MC = RegEx. Matches (output );
For ( Int I =   0 ; I < MC. Count; I ++ )
{
List. Add (MC [I]. value );
}
}
Foreach ( String Str In List)
{
Result + = Str +   " \ N " ;
}
}
Return Result;
}

Please take attention to the Code:PROCESS p = new process ();
We can useProcessObject To run the cmd.exe process, and then run the "appcmd list WP" command. after it, We can receive the output string, and analyze the string to get the result of what we want to get.
