【问题描述】：

我在将特定的现有网络适配器连接到现有交换机时遇到了相当大的困难。我可以通过在线发布的几个示例创建一个新的网络适配器并将其连接到我的虚拟机，但无法进行额外的步骤。以下函数找到我的网络适配器并正确执行，但不会建立连接。非常感谢任何帮助！

**EDIT: Solved, see code below.**

已解决：

    public static void ConnectInterfaceToSwitch(string VmName, string networkInterfaceName, string switchName)
    {
        ManagementScope scope = new ManagementScope(@"root\virtualization\v2");
        ManagementObject mgtSvc = WmiUtilities.GetVirtualMachineManagementService(scope);
        ManagementObject ethernetSwitch = NetworkingUtilities.FindEthernetSwitch(switchName, scope);
        ManagementObject virtualMachine = WmiUtilities.GetVirtualMachine(VmName, scope);
        ManagementObject virtualMachineSettings = WmiUtilities.GetVirtualMachineSettings(virtualMachine);
        ManagementObjectCollection portsSettings = virtualMachineSettings.GetRelated("Msvm_SyntheticEthernetPortSettingData", "Msvm_VirtualSystemSettingDataComponent", null, null, null, null, false, null);
        {                
            foreach (ManagementObject portSettings in portsSettings)
            {
                if (portSettings["ElementName"].Equals(networkInterfaceName))
                {
                    Console.WriteLine("Adapter found: " + networkInterfaceName);
                    ManagementObjectCollection connections = portSettings.GetRelated("Msvm_EthernetPortAllocationSettingData");
                    foreach (ManagementObject connection in connections)
                    {
                        connection["HostResource"] = new string[] { ethernetSwitch.Path.Path };
                        connection["EnabledState"] = 2; // 2 means "Enabled"    
                        ManagementBaseObject inParams = mgtSvc.GetMethodParameters("ModifyResourceSettings");
                        inParams["ResourceSettings"] = new string[] { connection.GetText(TextFormat.WmiDtd20) };

                        ManagementBaseObject outParams = mgtSvc.InvokeMethod("ModifyResourceSettings", inParams, null);
                        WmiUtilities.ValidateOutput(outParams, scope);

                        Console.WriteLine(string.Format(CultureInfo.CurrentCulture, "Connected VM '{0}' to switch '{1}'.", VmName, switchName));
                    }
                }
            }
        }
    }
