Window DialogResult Does not contain definition

Hey so I have this code bellow which gives the following errors, Can anyone explain what my problem is please.

Error   2   'System.Nullable<bool>' does not contain a definition
for 'Yes' and no extension   method 'Yes' accepting a first argument of type  
'System.Nullable<bool>' could be found (are you missing a using directive or an assembly 
reference?)



 var dialogResult = MessageBox.Show("Sure", "Some Title", MessageBoxButton.YesNo, MessageBoxImage.Question);
            if (dialogResult == DialogResult.Yes)
            {
                tw.hashtagList(body);
            }
            else if (dialogResult == DialogResult.No)
            {
                var dialogResult2 = MessageBox.Show("Sure", "Some Title", MessageBoxButton.YesNo, MessageBoxImage.Question);
                if (dialogResult2 == DialogResult.Yes)
                {
                    tw.mentionList(body);
                }

            }

It seem to me that you are using WPF.

WPF message box differs from Windows forms one. Here are WPF message box example:

void showMessageBoxButton_Click(object sender, RoutedEventArgs e) {
  // Configure message box 
  string message = "Hello, MessageBox!";
  string caption = "Caption text";
  MessageBoxButton buttons = MessageBoxButton.OKCancel;
  MessageBoxImage icon = MessageBoxImage.Information;
  // Show message box
  MessageBoxResult result = MessageBox.Show(message, caption, buttons, icon);
}

For more information follow the MSDN link: http://msdn.microsoft.com/en-us/library/ms602949.aspx
