Thanx Roman I tried giving command line arguments in Project->Proprties->Configuration Properties->Debugging. It works fine. If every time I want to give a different value I have to set the value there only. thnx again.

Can anyone tell me is there any difference between the usual DOS Command Prompt and the Visual Studio.NET Command Prompt provided with the Visual studio.NET?:confused: Can I run a C# Console application which takes Command line arugent from the Visul Studio itself without using the Command Prompt?:doh: Thanx.....:-O
