public sealed class MessageBox

The MessageBox type exposes the following members.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodStatic memberShow(String)Displays a message box that contains the specified text and an OK button.
Public methodStatic memberShow(String, String, MessageBoxButton)Displays a message box that contains the specified text, title bar caption, and response buttons.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The MessageBox class provides a static Show method that you can use to display a message in a simple dialog box. The dialog box is modal and provides an OK button.

An overload of the Show method enables you to specify a title bar caption and an optional Cancel button. If you display a Cancel button, you can use the return value of the method to determine the user's response.

The following example code demonstrates how to use this class.

MessageBoxResult result = 
    MessageBox.Show("Would you like to see the simple version?", 
    "MessageBox Example", MessageBoxButton.OKCancel);

if (result == MessageBoxResult.OK)
    MessageBox.Show("No caption, one button.");

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
