示例1:
// Initialize a text changed listener.
// An instance of TextPatternRange will become invalid if
// one of the following occurs:
// 1) The text in the provider changes via some user activity.
// 2) ValuePattern.SetValue is used to programatically change
// the value of the text in the provider.
// The only way the client application can detect if the text
// has changed (to ensure that the ranges are still valid),
// is by setting a listener for the TextChanged event of
// the TextPattern. If this event is raised, the client needs
// to update the targetDocumentRange member data to ensure the
// user is working with the updated text.
// Clients must always anticipate the possibility that the text
// can change underneath them.
