You have missed the MessageBoxButtonargument. Try the following:
你错过了MessageBoxButton辩论。请尝试以下操作：
MessageBox.Show("Added successfully", "Alert", MessageBoxButton.OK, MessageBoxImage.Information);
Make sure you are using MessageBoxfrom System.Windowsnamespace, not System.Windows.Forms.
确保您使用的是MessageBoxfromSystem.Windows命名空间，而不是System.Windows.Forms.
