Run CMD Commands Using C#

Sometimes, when working with a C# project, we may want to run CMD Command using C# and show its output or get output, so in this article, I have mentioned how to Execute Command Prompt(CMD) commands from C# with a console application example.

So here is the simple console application program where we will execute CMD command "ipconfig" using C#.

using System;
using System.Diagnostics;

namespace CMDCommandUsingCsharp
{
    public class Program
    {
        static void Main(string[] args)
        {
            var proc1 = new ProcessStartInfo();

            //cmd command
            var command = "ipconfig";

            // '/c' tells cmd that we want it to execute the command that follows, and then exit.
            System.Diagnostics.ProcessStartInfo procStartInfo = new System.Diagnostics.ProcessStartInfo("cmd", "/c " + command);

            // The following commands are needed to redirect the standard output. 
            //This means that it will be redirected to the Process.StandardOutput StreamReader.
            procStartInfo.RedirectStandardOutput = true;
            procStartInfo.UseShellExecute = false;
            // Do not create the black window.
            procStartInfo.CreateNoWindow = true;
            // Now we create a process, assign its ProcessStartInfo and start it
            System.Diagnostics.Process proc = new System.Diagnostics.Process();
            proc.StartInfo = procStartInfo;
            proc.Start();

            // Get the output into a string
            string result = proc.StandardOutput.ReadToEnd();

            // Display the command output.
            Console.WriteLine(result);

        }
    }
}

I have explained some important parts of the code using Comments.

Output:

In the above code,

• UseShellExecute Gets or sets a value indicating whether to use the operating system shell to start the process.
• RedirectStandardOutput redirects the standard output
• CreateNoWindow true if the process should be started without creating a new window to contain it, otherwise, false.

In the above code, you can also pass parameters with Commands while executing CMD Commands.
