using (ServerManager mgr = new ServerManager())
{
    for (int i = 0; i < mgr.Sites.Count; i++)
   {
        Log.Info("服务器目前存在网站", mgr.Sites.Count.ToString());//这地方直接就出错了，读取不到Sites网站的集合，请问是什么问题，同时要什么操作权限呢，怎么设置 
        foreach (Microsoft.Web.Administration.Binding b in mgr.Sites[i].Bindings)
       {
            temp = b.BindingInformation;
            if (temp.IndexOf('*') < 0)
            {
                temp = "*" + temp;
            }
            if (temp.Equals(bindingInfo))
           {
                return true;
           }
       }
   }
}
