How do I get the PrivilegedProcessorTime and UserProcessorTime for the current thread

I found several examples of how to get the PrivilegedProcessorTime and UserProcessorTime for a process and for all threads, but how do I get the PrivilegedProcessorTime and UserProcessorTime for the current managed thread.

private void button1_Click(object sender, EventArgs e)
{
    ThreadPool.QueueUserWorkItem(new WaitCallback(WorkCore));
}

static void WorkCore(Object stateInfo)
{
    // Code to get and do work
    // Code to get and log PrivilegedProcessorTime and UserProcessorTime
}

From stackoverflow

• I got this to work but AppDomain.GetCurrentThreadId has been deprecated

  static void WorkCore(Object stateInfo) 
  { 
      // Code to get and do work 
      // Code to get and log PrivilegedProcessorTime and UserProcessorTime
      ProcessThreadCollection m_Threads = Process.GetCurrentProcess().Threads;
      foreach(ProcessThread t in m_Threads)
      {
         if (t.Id == AppDomain.GetCurrentThreadId())
         {
            sw.WriteLine("User Time " + t.UserProcessorTime.ToString(@"d\:hh\:mm\:ss"));
            sw.WriteLine("Kernel Time " + t.PrivilegedProcessorTime.TotalSeconds.ToString("F0") + " sec");
         }
      }
  }
