Avoiding InvokeRequired

Just read a good article to do cross-thread calling in an easy and elegant way.

It is amazing for its simplicity and elegancy:

  1. 1 static class ControlExtensions
  2.  2 {
  3.  3   public static void InvokeOnOwnerThread<T>(this T control, Action<T> invoker) where T : Control
  4.  4   {
  5.  5     if (control.InvokeRequired)
  6.  6       control.Invoke(invoker, control);
  7.  7     else
  8.  8       invoker(control);
  9.  9   }
  10. 10 }

Only 10 lines to make the further calling a single line and extremely easy to read, very beautiful the way I like.

  1. private void UpdateTextBoxFromSomeThread(string message)
  2. {
  3.   textBox1.InvokeOnOwnerThread((txtBox) => txtBox.Text = message);  
  4. }

Would like to give all the credits to its author.
