Specifies constants defining the default button on a MessageBox.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
| Member name | Description | |

| Button1 | The first button on the message box is the default button. | |
| Button2 | The second button on the message box is the default button. | |
| Button3 | The third button on the message box is the default button. |
This enumeration is used by the MessageBox class.
The following code example demonstrates how to display a MessageBox with the options supported by this overload of Show. After verifying that a string variable, ServerName, is empty, the example displays a MessageBox with a question box icon, offering the user the option to cancel the operation. The example uses the RightAlign member of the MessageBoxOptions enumeration to align the text to the right edge of the dialog box. If the Show method's return value evaluates to Yes, the form that displayed the MessageBox is closed.
