Running or Executing an EXE file from within application.

We have to first import System.Diagnostics Namespace then use the Process class.
Suppose,we have to launch Notepad,

Using System.Diagnostics;
Process proc = new Process();      
proc.StartInfo.FileName = @"Notepad.exe";   
proc.StartInfo.Arguments = "";   
proc.Start();

After executing above code,Notepad will be opened.
