Running in IDE or EXE in C# VS 2010

check task manager .. if the process for your exe says

exename.vshost.exe (it is run from your IDE)

if it says just exename.exe (it is run directly using the exe)

but i wan to check inside from application not from task manager.

get the list of all running process using this:
http://www.howtogeek.com/howto/programming/get-a-list-of-running-processes-in-c/

and check for exename.vshost.exe in the list.

but how can i match myapplcation exe with process list.

or is any another way ?

or just check debugger.isattached

The way most people do it is with the following property:

// Sample for the Environment.UserInteractive property
using System;

class Sample 
{
    public static void Main() 
    {
    Console.WriteLine();
    Console.WriteLine("UserInteractive: {0}", Environment.UserInteractive);
    }
}
/*
This example produces the following results:

UserInteractive: True
*/
