Beispiele

Das folgende Codebeispiel zeigt die Verwendung der SessionChangeDescription Klasse in einer Implementierung von der OnSessionChange Methode in einer Klasse abgeleitet ServiceBase.The following code example shows the use of the SessionChangeDescription class in an implementation of the OnSessionChange method in a class derived from ServiceBase. Dieses Codebeispiel ist Teil eines umfangreicheren Beispiels für die ServiceBase Klasse.This code example is part of a larger example provided for the ServiceBase class.
