Get a List of Running Processes in C#

By Lowell Heddings on November 23rd, 2006

The System.Diagnostics namespace contains functions that allow you to manage processes, threads, eventlogs and performance information.

The System.Diagnostics.Process object gives you access to functionality enabling you to manage system processes. We will use this object to get a list of running processes.

Add this line to your using list:

using System.Diagnostics;

Now you can get a list of the processes with the Process.GetProcesses() method, as seen in this example:

Process[] processlist = Process.GetProcesses();

foreach(Process theprocess in processlist){
Console.WriteLine(“Process: {0} ID: {1}”, theprocess.ProcessName, theprocess.Id);
}

Some interesting properties of the Process object:

p.StartTime (Shows the time the process started)
p.TotalProcessorTime (Shows the amount of CPU time the process has taken)
p.Threads ( gives access to the collection of threads in the process)

The .NET framework really makes things simple!
