How To Start And Stop A Continuously Running Background Worker Using A Button

Question

Let's say I have a background worker like this:

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
             while(true)
             {
                  //Kill zombies
             }
        }

How can I make this background worker start and stop using a button on a WinForm?

Maybe you can use a manualresetevent like this, I didn't debug this but worth a shot. If it works you won't be having the thread spin its wheels while it's waiting

ManualResetEvent run = new ManualResetEvent(true);

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e) 
{ 
     while(run.WaitOne()) 
     { 
         //Kill zombies 
     } 
} 

private void War() 
{ 
    run.Set();
} 

private void Peace() 
{ 
    run.Reset();
}
