SMO ManagedComputer.ServiceInstances为空

我正在尝试使用SMO(VS2010,SQL Server 2008)连接到SQL Server并查看服务器协议配置。我可以连接并列出服务和clientprotocols以及运行mssqlserver服务的帐户。但是,serverInstances集合为空。目标服务器上的唯一实例是默认实例(mssqlserver),不应该在集合中吗?如何获取它的实例以便检查serverprotocols集合?下面是我使用的代码:

    class Program
{
    static void Main(string[] args)
    {
        //machine hosting installed sql server instance
        ManagedComputer host = new ManagedComputer("fully-qualified.host.name");


        if (host.ServerInstances.Count != 0)
        {
            //why is this 0? Is it because only the DEFAULT instance exists?
            Console.WriteLine("/////////////// INSTANCES ////////////////");
            foreach (ServerInstance inst in host.ServerInstances)
            {
                Console.WriteLine(inst.Name);
            }
        }

        Console.WriteLine("/////////////// SERVICES ////////////////");
        // enumerate sql services (looking for MSSSQLSERVER)
        foreach (Service svc in host.Services)
        {
            Console.WriteLine(svc.Name);
        }

        Console.WriteLine("/////////////// DETAILS ////////////////");

        // get name of MSSQLSERVER instance from user (pick from list above)
        Service mssqlserver = host.Services["MSSQLSERVER"];

        // print service account: .\{account} == "local account", "LocalSystem", "NetworkService", {domain}\{account} == "domain account"
        Console.WriteLine("Service Account: {0}", mssqlserver.ServiceAccount);

        // get client protocols
        foreach (ClientProtocol cp in host.ClientProtocols)
        {
            Console.WriteLine("{0} {1} ({2})", cp.Order, cp.DisplayName, cp.IsEnabled ? "Enabled" : "Disabled");
        }

    }
}

我也试过:

            Urn u = new Urn("ManagedComputer[@Name='fully-qualified.host.name']/ServerInstance[@Name='MSSQLSERVER']/ServerProtocol[@Name='Tcp']");
        ServerProtocol tcp = host.GetSmoObject(u) as ServerProtocol;
        if (tcp != null)
        {
            Console.WriteLine("{0}", tcp.DisplayName);
        }

但我收到一条错误信息:“不支持子表达式”。有什么问题吗?

要在服务器实例列表中获取结果,需要显式设置:

host.ConnectionSettings.ProviderArchitecture = ProviderArchitecture.Use64bit;

或

host.ConnectionSettings.ProviderArchitecture = ProviderArchitecture.Use32bit;

所以我一直没有找到答案,但我想出了一个解决办法。

            ManagedComputer host = new ManagedComputer(hostName);

        Server server = new Server();
        Console.WriteLine("TcpEnabled: {0}", server.TcpEnabled);

这使我得到了我需要的,我更希望能够枚举服务器协议,但这将允许我验证非常最小。
