Thread.CurrentThread Property in C#

The Thread.CurrentThread propertyin C# is used to get the currently running thread.

Syntax

The syntax is as follows -

public static System.Threading.Thread CurrentThread { get; }

Example

Let us now see an example -

using System;
using System.Threading;
public class Demo {
   public static void Main() {
      Thread thread = new Thread(new ThreadStart(demo1));
      ThreadPool.QueueUserWorkItem(new WaitCallback(demo2));
      thread = Thread.CurrentThread;
      thread.Name ="Demo Thread";
      Console.WriteLine("Current running Thread = "+thread.Name);
      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 running Thread = Demo Thread
Current state of Thread = Running
ManagedThreadId = 20
Thread belongs to managed thread pool? = True

Example

Let us now see another example -

using System;
using System.Threading;
public class Demo {
   public static void Main() {
      Thread thread = new Thread(new ThreadStart(demo1));
      ThreadPool.QueueUserWorkItem(new WaitCallback(demo2));
      thread = Thread.CurrentThread;
      thread.Name ="Demo Thread";
      Console.WriteLine("Current running Thread = "+thread.Name);
      Console.WriteLine("Current state of Thread = "+thread.ThreadState);
      Console.WriteLine("ManagedThreadId = "+thread.ManagedThreadId);
      Console.WriteLine("Thread Id: {0}", Thread.CurrentThread.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 running Thread = Demo Thread
Current state of Thread = Running
ManagedThreadId = 29
Thread Id: 29
Thread belongs to managed thread pool? = True
