System.FileNotFound exception

Question

So I am trying to automatically launch mmc compmgmt.msc with the only switch it seems to have (/computer:\). It works just fine from a local run box, but not by utilizing Process.Start. Here is the offending line:

Process.Start("mmc c:\\windows\\system32\\compmgmt.msc /computer:\\\\" + computerNameTextBox.Text.ToString());

Any ideas? I've tried using @ as well, with the same results, so it doesn't seem to be an escape character issue...it's something else...

PLEASE NOTE: stack overflow modified the escape characters in the above text string. They are properly there

Not on point, but isn't `computerNameTextBox.Text.ToString()` redundant? Could be just `computerNameTextBox.Text`, right? — DonBoitnott, Jan 21 '14 at 18:09

The command and arguments must be passed as separate parameters. Use this overload.

I facepalmed so hard ha ha ha. Thank you, my good sir. When SO allows it, I will accept this as an answer. Been grinding this code for a good solid 36 hours, kinda getting tunnel vision. – Christopher D Albert Jan 21 '14 at 18:08

You have to use separate parameters, this will not work at all. Process.Start has an overload to do this.

You use the Process.Start() method incorrectly. It should look like this

var startInfo = new ProcessStartInfo("mmc");
startInfo.Arguments = "c:\\windows\\system32\\compmgmt.msc /computer:\\\\" 
                       + computerNameTextBox.Text.ToString();
Process.Start(startInfo);

For more information, look at this SO question.
