C# 远程服务器 创建、修改、删除 应用程序池 网站

首先 C# 操作 站点 需要 引用Microsoft.Web.Administration.dll 文件，创建站点我们一般需要 远程服务的IP，网站名称、端口、物理路径；这里默认网站名称和应用程序池名称一致。

应用程序池默认不启动，应为刚创建站点是没有对应真实的物理文件，修改 队列长度、启动模式、回收时间、最大工作进程， 以及日志路径。修改的时候如果修改站点物理路径的话，我们需要把文件 从旧得目录拷贝到新的目录下，删除站点就比较简单了。

但是站点应用程序池的停止 和启动就比较难搞了，不是调用stop后就马上能停止的，我们需要一个检测状态的机制以及重试机制，如果没有停止 就等待一段时间，因为只有应用程序池完全停止后我们在可以拷贝文件到应用程序目录下；启动也是一样的需要一个 等待 和重试的机制。相关code如下：
