Question

How do I execute a command-line program from C# and get back the STD OUT results? Specifically, I want to execute DIFF on two files that are programmatically selected and write the results to a text box.

Answer 1

// Start the child process.  Process p = new Process();  // Redirect the output stream of the child process.  p.StartInfo.UseShellExecute = false;  p.StartInfo.RedirectStandardOutput = true;  p.StartInfo.FileName = 'YOURBATCHFILE.bat';  p.Start();  // Do not wait for the child process to exit before  // reading to the end of its redirected stream.  // p.WaitForExit();  // Read the output stream first and then wait.  string output = p.StandardOutput.ReadToEnd();  p.WaitForExit(); 

Code is from MSDN.
