c# - 从 C# 管理 Windows 集群

Question

我正在尝试在 C# 中启动/停止基于 Windows 的集群，下面是我目前正在使用的代码......当我进入下面的 TakeOffLine 函数时，我从 System.Management 得到一个“未找到”异常.ManagementStatus.NotFound。不确定到底是什么没有被发现？如果有更好的(替代)方法，请告诉我。

谢谢!

using System.Management;
class App
{
    public static void Main()
    {
        string clusterName = "clusterHex";    // cluster alias
        string custerGroupResource = "clusterHex.internal.com"; // Cluster group name

        ConnectionOptions options = new ConnectionOptions();
        options.Authentication = System.Management.AuthenticationLevel.PacketPrivacy;

        // Connect with the mscluster WMI namespace on the cluster named "MyCluster"
        ManagementScope s = new ManagementScope("\\\\" + clusterName +
            "\\root\\mscluster", options);

        ManagementPath p = new ManagementPath("Mscluster_Clustergroup.Name='" + custerGroupResource + "'");

        using (ManagementObject clrg = new ManagementObject(s, p, null))
        {
            // Take clustergroup off line and read its status property when done
            TakeOffLine(clrg);
            clrg.Get();
            Console.WriteLine(clrg["Status"]);
            System.Threading.Thread.Sleep(3000);    // Sleep for a while
            // Bring back online  and get status.
            BringOnLine(clrg);
            clrg.Get();
            Console.WriteLine(clrg["Status"]);

        }
    }
    static void TakeOffLine(ManagementObject resourceGroup)
    {
        ManagementBaseObject outParams =
        resourceGroup.InvokeMethod("Takeoffline", null, null);
    }
    static void BringOnLine(ManagementObject resourceGroup)
    {
        ManagementBaseObject outParams =
        resourceGroup.InvokeMethod("Takeoffline", null, null);
    }
}

看起来您的方法调用中缺少大小写。根据 msdn，您必须使用 TakeOffline

static void TakeOffLine(ManagementObject resourceGroup)
{
    ManagementBaseObject outParams =
    resourceGroup.InvokeMethod("TakeOffline", null, null);
}
