How to Cancel a Thread?

Question

In case of BackgroundWorker, a cancel can be reported by the e.Cancel - property of the DoWork - event handler.

How can I achieve the same

Answer 1

Generally you do it by the thread's execute being a delegate to a method on an object, with that object exposing a Cancel property, and the long-running operation periodically chercking that property for tru to determine whether to exit.

for example

public class MyLongTunningTask
{
   public MyLongRunninTask() {}
   public volatile bool Cancel {get; set; }

   public void ExecuteLongRunningTask()
   {
     while(!this.Cancel)
     {
         // Do something long running.
        // you may still like to check Cancel periodically and exit gracefully if its true
     }
   }
}

Then elsewhere:

var longRunning = new MyLongTunningTask();
Thread myThread = new Thread(new ThreadStart(longRunning.ExecuteLongRunningTask));

myThread.Start();

// somewhere else
longRunning.Cancel = true;
