Question

我正在尝试使用SMO（VS 2010，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以及正在运行的MSSQLSERVER服务帐户。但是，ServerInstances集合为空。目标服务器上唯一的实例是默认（MSSQLSERVER），不应该在集合中吗？如何获取它的实例以便我可以检查ServerProtocols集合？这是我正在使用的代码：

    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");
        }

    }
}

我也试过了：

            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);
        }

但是我收到一条错误消息，指出：“不支持子表达式。”任何想法有什么不对？

Answer 1

要在ServerInstances列表中获取结果，您需要显式设置：

host.ConnectionSettings.ProviderArchitecture = ProviderArchitecture.Use64bit;

或

host.ConnectionSettings.ProviderArchitecture = ProviderArchitecture.Use32bit;

Answer 2

所以我从来没有找到答案，但我想出了一个解决方法。

            ManagedComputer host = new ManagedComputer(hostName);

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

这让我得到了我需要的东西，我希望能够枚举ServerProtocols，但这将使我能够验证最低限度。

SMO ManagedComputer.ServiceInstances为空
