How to get the current ProcessID?

Question

What's the simplest way to obtain the current process ID from within your own application, using the .NET Framework?

Answer 1

Get a reference to the current process and use System.Diagnostics's Process.Id property:

int nProcessID = Process.GetCurrentProcess().Id; 

Answer 2

Process.GetCurrentProcess().Id 

Or, since the Process class is IDisposable, and the Process ID isn't going to change while your application's running, you could have a helper class with a static property:

public static int ProcessId {     get      {         if (_processId == null)         {             using(var thisProcess = System.Diagnostics.Process.GetCurrentProcess())             {                 _processId = thisProcess.Id;             }         }         return _processId.Value;     } } private static int? _processId;
