C# - How do I find the process id of a separate program?

I need the process ID for a program that is already running on the computer. How would I go about doing this? (The process isn't started from Process.Start())

Use GetProcessesByName or just GetProcesses with a bit of LINQ, depending on how you intend to identify the program.

using System;
using System.Diagnostics;
using System.ComponentModel;


void Example()
{
        // Get all processes running on the local computer.
        var localProcesses = Process.GetProcesses();

        //Get all processes with a name that contain "Foo" in the title
        var fooProcess = localProcesses.Where(p => p.MainWindowTitle.Contains("Foo"));

        // Get all instances of Notepad running on the local computer.
        var notepad = Process.GetProcessesByName("notepad").Single();
}

Once you have the Process object, you can get its ID with the Id property.

var id = process.Id;
