Answer 1

您可以将答案存储在DialogResult对象中.然后你可以分析这样的答案:

       DialogResult result = MessageBox.Show("this item is already in the system, do you want to add it anyway ?", "Question",MessageBoxButtons.YesNoCancel);

       if (result == DialogResult.Yes) {
           //your code here
       } else if (result == DialogResult.Cancel) {
           //your code here
       } else if (result == DialogResult.No) {
          // your code here
       }

来自http://msdn.microsoft.com/en-us/library/0x49kd7z.aspx:

        result = MessageBox.Show(message, caption, buttons);
        if (result == System.Windows.Forms.DialogResult.Yes)
        {
            // Closes the parent form.
            this.Close();
        }
