C# How to Get Output from CMD (Command = “Defrag c: /U”) Before Proccess Ends.

I'm calling Defrag.exe from my c# application. I want to get output of defragmentation proccess when it's updated.

I want this output(in red rectangle) to be printed in my application.(When 11% progress percentage updated it should also be printed.) :



I'm using this code:

Process selectedProc = new Process();
selectedProc.StartInfo.UseShellExecute = false;
selectedProc.StartInfo.RedirectStandardOutput = true;
selectedProc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
selectedProc.StartInfo.CreateNoWindow = true;

selectedProc.OutputDataReceived += (sender, e) =>
{
Debug.WriteLine(e.Data);
};

selectedProc.StartInfo.WorkingDirectory = System.IO.Path.GetPathRoot(Environment.SystemDirectory);
selectedProc.StartInfo.FileName = System.IO.Path.Combine(Environment.SystemDirectory, 'defrag.exe');
selectedProc.StartInfo.Arguments = 'C: /U';
selectedProc.Start();
selectedProc.BeginOutputReadLine();


After sometime i'm closing process with this code:

selectedProc.Kill();


Between process.Start() and process.Kill() i'm not seeing any output printed on debug section in Visual Studio. Not even after defrag process ended. Where is the problem ?
