[C#]通用守护进程服务
摘要
很多情况下，都会使用windows服务做一些任务，但总会有一些异常，导致服务停止。这个时候，开发人员又不能立马解决问题，所以做一个守护者服务还是很有必要的。当检测到服务停止了，重启一下服务，等开发人员到位了，再排查错误日志。
代码
app.config
<?xml version="1.0" encoding="utf-8" ?><configuration> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /> </startup> <appSettings> <!--要守护的服务的服务名称--> <add key="toWatchServiceName" value=http://www.mamicode.com/""/> <!--守护服务的名称--> <add key="serviceName" value=http://www.mamicode.com/"邮件提醒服务守护服务"/> <!--每1分钟检查一次 以秒为单位--> <add key="timerInterval" value=http://www.mamicode.com/"60"/> </appSettings></configuration>
