C# 远程服务器 安装、卸载 Windows 服务，读取远程注册表，关闭杀掉远程进程

这里安装windows服务我们用sc命令，这里需要远程服务器IP，服务名称、显示名称、描述以及执行文件，安装后需要验证服务是否安装成功，验证方法可以直接调用ServiceController来查询服务，也可以通过远程注册表来查找服务的执行文件；那么卸载文件我们也就用SC命令了，卸载后需要检测是否卸载成功，修改显示名称和描述也用sc命令。至于停止和启动Windows服务我们可以用sc命令也可以用ServiceController的API，当停止失败的时候我们会强制杀掉远程进程，在卸载windows 服务我们需要关闭windows服务窗口，不然无法删除服务（服务被标记为已删除状态）。注意安装和卸载Windows服务是通过sc命令来执行的，把sc命令发送到服务器上，服务器需要一段执行时间，所以在远程注册表不一定马上体现安装和卸载的效果，这里我们需要有一个重试的机制。远程服务需要引用System.ServiceProcess，关闭远程进程需要引用 System.Management.dll 。先关code如下：
