        label10.Visible = false;
        pictureBox6.Visible = false;

    }

Yes, you need to hook the OutputDataReceived and ErrorDataReceived events and write functions that'll trigger an append to your textbox on a UI thread. e.g. see [this old question](http://stackoverflow.com/q/1145969/243245) — Rup, May 06 '16 at 10:18
Yea it's Works For me but .. not that what I want ... I need to Read it Step by step in exact mean I need to show what's happening now on CMD and past it on Textbot ... The way I made ,is wait the proc. to end and past the Result in text box ... is that possible to do something like this in C# ? — Abdo Hurbly, May 06 '16 at 10:28

If you hook the events you'll get the data step by step rather than all in one go. — Rup, May 06 '16 at 10:49
I would use a `RichTextBox`, not a `TextBox` because it's multiline by default and you can colorize standard Output and Error Output with different colors. — Clijsters, May 06 '16 at 13:43

Well you already set up everything as needed, the only thing missing is:

string consoleOutput = proc.StandardOutput.ReadToEnd();

Use this, then line will contain whole output

proc.Start();
string line = proc.StandardOutput.ReadToEnd();

or for one line

proc.Start();
string line = proc.StandardOutput.ReadLine();

and if you want output line by line then

while (!proc.StandardOutput.EndOfStream) {
    string line = proc.StandardOutput.ReadLine();
    // do your stuff
}

or you can try this one too, first remove proc.WaitForExit(); because ReadLine will wait until data is available or the stream is closed. When the stream is closed, ReadLine will return null.

string line;
while ((line = proc.StandardOutput.ReadLine())!=null) 
{
    // textbox.text = line or something like that
}
