C# Program to Kill a Thread

Create a thread first and start it −

// new thread
Thread thread = new Thread(c.display);
thread.Start();

Now display the thread and set a stop function to stop the working of the thread −

public void display() {
   while (!flag) {
      Console.WriteLine("It's Working");
      Thread.Sleep(2000);
   }
}
public void Stop() {
   flag = true;
   }
}

   static void Main(string[] args){
      MyClass c = new MyClass();      
      // new thread      
      Thread thread = new Thread(c.display);      
      thread.Start();      
      Console.WriteLine("Press any key to exit!");      
      Console.ReadKey();      
      c.Stop();      
       thread.Join();    
   }
}
public class MyClass {    
   private bool flag = false;    
   public void display() {      
      while (!flag) {        
         Console.WriteLine("It's Working");    
         Thread.Sleep(2000);      
       }    .
   }    .
   public void Stop() {      
      flag = true;    
   }
}

Output

It's Working
