Question

我们刚刚启动了一个新的Web服务器，并且在创建新的应用程序池时遇到了“未注册的类”。我正在使用下面的代码，但我不知道如何区分未注册的内容。任何想法都会很棒。

感谢。

string path = "IIS://" + server + "/W3SVC";
        string app_pools_path = path + "/AppPools";

        /error below.
        var app_pools = new DirectoryEntry(app_pools_path);

        foreach (DirectoryEntry app_pool in app_pools.Children)
        {
//do work
}

错误“Class no registered”错误代码：2147221164

Answer 1

在服务器上打开服务器管理器添加新功能==＆gt; Web服务器（IIS）==＆gt;管理工具==＆gt; IIS 6管理兼容性然后检查IIS6元数据库兼容性。使用原始连接字符串/路径

string path =＆＃34; IIS：//＆＃34; + server +＆＃34; / W3SVC＆＃34 ;; string app_pools_path = path +＆＃34; / AppPools＆＃34;;

请试试这个：

     private void StopAppPool(string app_Pool , string server)
    {
        try
        {

            ConnectionOptions co = new ConnectionOptions();
            co.Username = "DomainName\\UserName";
            co.Password = "UserPassword";
            string appPool = "W3SVC/AppPools/" + app_Pool;
            co.Impersonation = ImpersonationLevel.Impersonate;
            co.Authentication = AuthenticationLevel.PacketPrivacy;
            string objPath = "IISApplicationPool.Name='" + appPool + "'";

            ManagementScope scope = new ManagementScope(@"\\" + server + @"\root\MicrosoftIISv2", co);
            using (ManagementObject mc = new ManagementObject(objPath))
            {
                mc.Scope = scope;

                mc.InvokeMethod("Stop", null, null);
            }
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
            Console.WriteLine(e.StackTrace);
            Console.WriteLine(e.InnerException);
            Console.WriteLine(e.Data);
        }
       //Console.ReadLine();

    }

您应该避免使用DirectoryEntry来操纵IIS 7及更高版本。这是基于IIS ADSI接口的旧API，

IIS 6兼容性可能会帮助你，

最佳解决方案（对于C＃开发人员而言也是强类型且更方便）是Microsoft.Web.Administration，
