Do you mean you have use process class to start "cmd prompt" And want to display some output in it?
If so, there is no need to use RedirectStandardOutput property. This property means the output of an application is written to the
Process.StandardOutput stream.
// Setup the process with the ProcessStartInfo class.
ProcessStartInfo start = new ProcessStartInfo();
start.FileName = @"C:\7za.exe"; // Specify exe name not cmd exe.
start.UseShellExecute = false;
start.RedirectStandardOutput = true;
// Start the process.
using (Process process = Process.Start(start))
// Read in all the text from the process with the StreamReader.
using (StreamReader reader = process.StandardOutput)
string result = reader.ReadToEnd();
Console.Write(result);
Output
This section shows the output of the process.
7-Zip (A) 4.60 beta Copyright (c) 1999-2008 Igor Pavlov 2008-08-19
Usage: 7za <command> [<switches>...] <archive_name> [<file_names>...]
[<@listfiles...>]
So you can start a cmd exe.
Please also take a look at the article from codeproject
How to redirect Standard Input/Output of an application
In summary, the shutdown proces is invoked from my application, and it displays the output from the process in RichTextBox control.
Have a nice day!
