run external command c# in csharp

To run an external command in C#, you can use the Process class to start a new process and execute the command. Here is an example code:

main.cs
using System.Diagnostics;

ProcessStartInfo processInfo = new ProcessStartInfo("cmd.exe", "/c dir");
processInfo.CreateNoWindow = true;
processInfo.UseShellExecute = false;

Process process = new Process();
process.StartInfo = processInfo;
process.Start();

10 lines

In this example, we are using the ProcessStartInfo class to specify the command we want to run (cmd.exe) with some arguments (/c dir) in this case. Then we create a new Process instance and set the StartInfo property to the ProcessStartInfo instance we just created. Finally, we call the Start method to start the new process.

Note that you can configure the ProcessStartInfo instance to set additional properties such as the working directory, standard input/output/error, etc.
