C# 通过windows服务发送邮件 实例源码下载

【实例简介】通过注册服务，实现自动发送邮件

使用说明：

打开cmd
输入: 系统盘:\Windows\Microsoft.NET\Framework\v2.0.50727
输入:InstallUtil.exe 项目地址(如:InstallUtil.exe E:\Project\WServerSendEmail\WindowsServiceSendEmil\WindowsServiceSendEmil\bin\Debug\WindowsServiceSendEmil.exe)
会提示安装成功;
这时候右击我的电脑-管理-服务和应用程序-服务,在服务里面就可以找到Service1的服务,这个就是我们刚添加进去的.启动服务后就开始运行程序了;
如果你想调式,可以在vs里调式-附加到进程

卸载
打开cmd 
输入 sc delete 服务名称(如Service1)(注意:卸载前先停止服务)
