This is starting to sound like a new and different question. Perhaps you should create another one? — Rook, Nov 15 '14 at 12:49

To run CMD in administrator privilage, you simply have to run an application in administrator privilage.

But better way to call an program from console will be using Process object (not static method), where you have more options, eg. can read output, etc.

Process p = new Process();
p.StartInfo.CreateNoWindow = true;
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = "date";
p.StartInfo.Arguments = "";
p.Start();

Then to input data to the application you have to use StandardInput field of Process class

p.StandardInput.Write(string yourDate);

And at the end you can gently wait for application to finish it's job.

p.WaitForExit();

To read data from output you have to use this command:

string output = p.StandardOutput.ReadToEnd();

You can also read this line by line (if you have to):

string[] oLines = output.Split(new string[] { "\r\n", "\n" }, StringSplitOptions.None);

Should be p.StandardInput.Write**Line** in this case – Vlad Nov 15 '14 at 11:50 — Vlad, Nov 15 '14 at 11:50
