很简单,我想写一些事情日志.

protected override void OnStop()
    {
        // TODO: Add code here to perform any tear-down necessary to stop your service.
        if (!System.Diagnostics.EventLog.SourceExists("IvrService"))
        {
            System.Diagnostics.EventLog.CreateEventSource(
                "IvrService","IvrServiceLog");
        }
        EventLog eventLog1 = new System.Diagnostics.EventLog();
        eventLog1.Source = "IvrService";
        eventLog1.Log = "IvrServiceLog";
        try
        {
            eventLog1.WriteEntry("Successfully "+State.Stopped.ToString());
            IvrApplication.StopImmediate();
        }
        catch (Exception ex)
        {
           // eventLog1.WriteEntry(ex.Message);
        }
    }

例外是：

Failed to stop service. System.ArgumentException: The source 'IvrService' is not   registered in log 'IvrServiceLog'. (It is registered in log 'Application'.) " The Source   and Log properties must be matched,or you may set Log to the empty string,and it will automatically be matched to the Source property.
   at System.Diagnostics.EventLogInternal.VerifyAndCreateSource(String sourceName,String currentMachineName)
   at System.Diagnostics.EventLogInternal.WriteEntry(String message,EventLogEntryType type,Int32 eventID,Int16 category,Byte[] rawData)
   at System.Diagnostics.EventLog.WriteEntry(String message)

解决方法

错误信息告诉你什么是错误的.您已将事件源IvrService注册到应用程序日志,而不是IvrServiceLog. System.Diagnostics.EventLog.SourceExists验证源是否存在,但不是用于特定日志.

我的猜测是,您最初在应用程序日志中注册了该文件,然后将其更改为写入IvrServiceLog.

要清理您的开发机器,您可以简单地运行以下内容,然后您的代码应该继续工作.

System.Diagnostics.EventLog.DeleteEventSource("IvrService");
