c# - Passing an argument to cmd.exe

Question

I am attempting to ping a local computer from my C# program. To accomplish this, I'm using the following code.

System.Diagnostics.ProcessStartInfo proc = new System.Diagnostics.ProcessStartInfo();
proc.FileName = @"C:windowssystem32cmd.exe";
proc.Arguments = @"""ping 10.2.2.125""";
System.Diagnostics.Process.Start(proc);

This opens a command-line window, but ping is not invoked. What is the reason?

Answer 1

You need to include the "/c" argument to tell cmd.exe what you mean it to do:

proc.Arguments = "/c ping 10.2.2.125";

(You could call ping.exe directly of course. There are times when that's appropriate, and times when it's easier to call cmd.)
