Start a command line including arguments from C#

Question

I need to start a complete command line like "app.exe /arg1:1 /arg2:true" from my C# app.

Process.Start and ProcessStartInfo needs to have the filename and arguments property set. Is there a way to mimic a true shell-like execute (like the one when you press WIN+R)?

What deficiencies are you finding with using Process.Start? — Oded

How about a batch file starting the process and using Process.Start to start the batch file? — CodingBarfield

The command line is coming from a configuration file and is provided as a whole. I just want to mimic the WIN+R functionality. I think even VBScript has a way to do what I need... — Stefan Koell

Yes, you can launch cmd.exe with the full command-line you want to send as the arguments.

info.FileName = "cmd.exe"; info.Arguments = "app.exe /arg1:1 /arg2:true";

You'll probably need the /c switch to tell cmd.exe to execute app.exe.

I also thought about this solution but I don't like that the command window appears.

ProcessStartInfo.UseShellExecute makes Process.Start behave exactly like the Shell: http://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.useshellexecute.aspx

I'm aware of this property but this still requires me to pass in the command and the arguments separately.

I've found the solution I've been looking for: Executing another program from C#, do I need to parse the "command line" from registry myself?

Thanks again for your help!
