次のコード例の使用を示しています、SessionChangeDescriptionクラスの実装で、OnSessionChangeから派生したクラスのメソッドでServiceBaseします。The following code example shows the use of the SessionChangeDescription class in an implementation of the OnSessionChange method in a class derived from ServiceBase. このコード例が示されている例の一部、ServiceBaseクラス。This code example is part of a larger example provided for the ServiceBase class.
