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

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;
