Update UI from background Thread

Question

This is just a curious question. Which one is the best way to update UI from another thread. First, this one:

private delegate void MyDelegateMethod();
void          


        

Answer 1

The default Action delegate worked 90% of the time:

private void Log(String value)
{
    // Verify that we're on the same thread
    if (textBox1.InvokeRequired)
    {
        // We're not on the same thread - Invoke the UI thread
        textBox1.Invoke(new Action(Log), value);
        return;
    }

    // We're on the same thread - Update UI
    textBox1.Text += value + "\r\n";
}

private void OnSomethingHappened()
{
    Log("Something happened!");
}
