The MessageBox.Show method always returns a result, indicating which button a user clicked to dismiss the dialog box. If you choose, you can check the result to see which button the user clicked. The value returned will always be a member of the MessageBoxResult enumeration.
// Not checking result MessageBox.Show("Hi!"); // Always resturns MessageBoxResult.OK, since the dialog only has one button MessageBoxResult res = MessageBox.Show("Hello again");
In the above examples, the result didn’t really matter. But you often want to know which of two or more buttons the user clicked.
MessageBoxResult res = MessageBox.Show("Do you like brussel sprouts?", "Green Food", MessageBoxButton.YesNo); if (res == MessageBoxResult.No) MessageBox.Show("Me neither"); else MessageBox.Show("Wow, you're a cruciferous vegetable lover!");
