The MessageBox class provides a static Show method that you can use to display a message in a simple dialog box. The dialog box is modal and provides an OK button.

An overload of the Show method enables you to specify a title bar caption and an optional Cancel button. If you display a Cancel button, you can use the return value of the method to determine the user's response.

The message box may have a slightly different appearance on different platforms. For example, the message box includes an icon when it is displayed on a Macintosh.

The following example code demonstrates how to use this class.


MessageBoxResult result = 
    MessageBox.Show("Would you like to see the simple version?", 
    "MessageBox Example", MessageBoxButton.OKCancel);

if (result == MessageBoxResult.OK)
{
    MessageBox.Show("No caption, one button.");
}
