示例

下面的代码示例演示如何在 派生自 ServiceBase的Reason类中 方法的OnSessionChange实现中使用 属性。 此代码示例是为 ServiceBase 类提供的一个更大示例的一部分。

        // Handle a session change notice
        protected override void OnSessionChange(SessionChangeDescription changeDescription)
        {
#if LOGEVENTS
            EventLog.WriteEntry("SimpleService.OnSessionChange", DateTime.Now.ToLongTimeString() +
                " - Session change notice received: " +
                changeDescription.Reason.ToString() + "  Session ID: " +
                changeDescription.SessionId.ToString());
#endif

    ' Handle a session change notice
    Protected Overrides Sub OnSessionChange(ByVal changeDescription As SessionChangeDescription)
#If LOGEVENTS Then
        System.Diagnostics.EventLog.WriteEntry("SimpleService.OnSessionChange", DateTime.Now.ToLongTimeString() + " - Session change notice received: " + changeDescription.Reason.ToString() + "  Session ID: " + changeDescription.SessionId.ToString())
#End If
