Sometimes you'll want to run an external program, like bat, exe, or vbs. I find this especially useful for testing and deployment - I'll want to reset IIS or run a VBScript that initializes the environment, or call osql (the command line for SQL Server) to run a database script. Fortunately .Net provides a great way to do this using the System.Diagnostics namespace.
The simplest approach is a static utility method that can take the filename and command line arguments ike so:

This opens up a console window and runs the command. While it works for simple things, such as resetting IIS, there's two additional useful features we may want to do, especially for quick-running processes: (1) Run the process in a hidden window, (2) Wait for the process to exit. We can do both of these with code like the following:
public static void RunHiddenConsole(string strFileName, string strArguments, bool blnWaitForExit) { //run in process without showing dialog window: ProcessStartInfo psi = new ProcessStartInfo(); //psi.CreateNoWindow = true; psi.WindowStyle = ProcessWindowStyle.Hidden; psi.FileName = strFileName; psi.Arguments = strArguments; Process p = System.Diagnostics.Process.Start(psi); if (blnWaitForExit) p.WaitForExit(); } //end of method |
To run the process in a hidden window, we create a ProcessStartInfo object and specify its window style to be Hidden. We can then pass this ProcessStartInfo into the Process.Start method. To wait for the exit, we create a process object from the Process.Start method, and use its WaitForExit method.
Note that this is very context-independent functionality, and is therefore great to put into your own utilities class that you can reuse from project to project.
Exactly What I Needed Got No Joy with SHELL Command.
Awesome little piece of code here! This is exactly what I was looking for
