Question

When working with a command line program, via a c# class method.

How do you determine if the commandline program was successfully executed and the operation it has performed is ok or has failed?

Also how do you get the screen commandline output into the c# class method?

Answer 1

You can use the Process class to execute a command line command.

The following code captures the standard output to output, and assigns the processes exit code to exitCode.

using (Process p = new Process())
{
    p.StartInfo.FileName = exeName;
    p.StartInfo.Arguments = args;
    p.StartInfo.UseShellExecute = false;
    p.StartInfo.RedirectStandardOutput = true;
    p.Start();
    string output = p.StandardOutput.ReadToEnd();
    p.WaitForExit();
    int exitCode = p.ExitCode;
}
