RetryCancel MessageBox

Im using System.Windows.MessageBox.Show() to display a dialog to the user. One overload lets me set the buttons that appear using the System.Windows.MessageBoxButton enum. However, it seems to lack a RetryCancel option that my googling suggests it should 开发者_JS百科have.

• Am I missing something?
• How do I display a RetryCancel messagebox?

You aren't missing anything. There's a RetryCancel value:

MessageBox.Show("text", "caption", MessageBoxButtons.RetryCancel);

Remark: Do not mistake with WPF's MessageBoxButton enumeration which doesn't have such value.

System.Windows is WPF. System.Windows.Forms is WinForms.
