How to check current state of a thread in C#?

To check the current state of a thread, the code is as follows −

Example

 Live Demo

using System;
using System.Threading;
public class Demo {
   public static void Main(){
      Thread thread = new Thread(new ThreadStart(demo1));
      ThreadPool.QueueUserWorkItem(new WaitCallback(demo2));
      Console.WriteLine("Current state of Thread = "+thread.ThreadState);
      Console.WriteLine("ManagedThreadId = "+thread.ManagedThreadId);
   }
   public static void demo1(){
      Thread.Sleep(2000);
   }
   public static void demo2(object stateInfo){
      Console.WriteLine("Thread belongs to managed thread pool? = "+Thread.CurrentThread.IsThreadPoolThread);
   }
}

Output

This will produce the following output −

Current state of Thread = Unstarted
ManagedThreadId = 3

Example

Let us now see another example −

 Live Demo

using System;
using System.Threading;
public class Demo {
   public static void Main(){
      Thread thread = new Thread(new ThreadStart(demo));
      Console.WriteLine("ManagedThreadId = "+thread.ManagedThreadId);
      Console.WriteLine("Current state of Thread = "+thread.ThreadState);
      thread.Start();
      Console.WriteLine("Current state of Thread = "+thread.ThreadState);
   }
   public static void demo(){
      Console.WriteLine("Thread belongs to managed thread pool? = "+Thread.CurrentThread.IsThreadPoolThread);
   }
}

Output

This will produce the following output −

ManagedThreadId = 3
Current state of Thread = Unstarted
Thread belongs to managed thread pool? = False
Current state of Thread = Running
