在 Windows 服务程序中记录事件 [英] Logging Events in a Windows Service Program

问题描述

我创建了一个 Windows 服务程序，我希望我的错误严格写入 Windows eventLog.所以我按照代码项目文章中的这些步骤操作:

但是当我启动或停止服务时，我没有看到我在事件查看器窗口中创建的事件日志中写入的任何自定义日志消息.另外我如何指定消息是由于错误还是只是信息?

解决方案

首先，MSDN 是你的朋友.请务必查看链接，因为有一些潜在的问题值得了解.

本质上，您创建了一个 EventLog 对象:

this.ServiceName = "MyService";this.EventLog = new System.Diagnostics.EventLog();this.EventLog.Source = this.ServiceName;this.EventLog.Log = "应用程序";

您还需要创建一个源，如果上述源不存在:

((ISupportInitialize)(this.EventLog)).BeginInit();如果 (!EventLog.SourceExists(this.EventLog.Source)){EventLog.CreateEventSource(this.EventLog.Source, this.EventLog.Log);}((ISupportInitialize)(this.EventLog)).EndInit();

然后简单地使用它:

this.EventLog.WriteEntry("我的事件日志消息.", EventLogEntryType.Information);

其实很简单.

I have created a Windows service program and I want my error to strictly be written to the Windows eventLog. So I followed these steps from code project article:

http://www.codeproject.com/KB/dotnet/simplewindowsservice.aspx

But I don't see any of the custom log messages I wrote in the event logs created in the event viewer window when I start or stop the service. Also how do I specify whether the message was due to an error or is just info?

解决方案

First, MSDN is your friend. Make sure you check out the link, as there are some potential gotchas worth knowing.

Essentially, you create an EventLog object:

this.ServiceName = "MyService";
this.EventLog = new System.Diagnostics.EventLog();
this.EventLog.Source = this.ServiceName;
this.EventLog.Log = "Application";

You also need to create a source, if the above source doesn't exist:

((ISupportInitialize)(this.EventLog)).BeginInit();
if (!EventLog.SourceExists(this.EventLog.Source))
{
    EventLog.CreateEventSource(this.EventLog.Source, this.EventLog.Log);
}
((ISupportInitialize)(this.EventLog)).EndInit();

and then simply use it:

this.EventLog.WriteEntry("My Eventlog message.", EventLogEntryType.Information);

it's actually pretty simple.
