如何使用BeginInvoke for button.PerformClick（）从另一个线程 - 跨线程调用

Question

I have a method:

 private void RecordButton_Click(object sender, EventArgs e) {

  }

and in the other method which was called by other thread:

 private void raiseAlarm() {
                RecordButton.PerformClick();//EXCEPTION HERE
        }

I get an exception that indicates the PerformClick() is invoked in the other thread therefore I should make a cross thread call. What should I write instead to PerformClick() ?

Answer 1

here how you can by pass this exception

private void raiseAlarm()
        {
            if (this.InvokeRequired)
            {

                Action action = raiseAlarm;  
                this.Invoke( action); 
            }
            else
            {

               RecordButton.PerformClick();
            }

        }

or you can use BeginInvoke which executes the specified delegate asynchronously on the thread that the control's underlying handle was created on.

  private void raiseAlarm()
        {

            this.BeginInvoke(new Action(raiseAlarm)); 



        }
