功能说明：C#创建一个windows服务，服务启动时D:\mcWindowsService.txt写入数据，服务运行期间每隔两秒写入当前时间。
原理这些就不说了，三语两语说不清楚，直接贴一个实例。不能贴图片！！那个压缩文里面是word文档！！有图有真相
1．建立空白项目
2.添加创建windows服务需要的引用，选择System.ServiceProcess。
3．创建服务类，继承ServiceBase，类的源代码在后面。
4.
添加windows服务的安装类。
（1）在类名或者解决方案中新建视图：
（2）上一步后会出来类的视图，右键选择查看设计器：
（3）在设计视图里面添加安装器（有可能会弹出警告框，如图，不用管）：
服务创建完成！
安装运行就不用说了吧！！
