问题：无法使用Msvm_VirtualEthernetSwitchManagementService和AddFeatureSettings方法将VLAN分配给Hyper-V虚拟机。
有人可以指出我在做什么错吗？
我还注意到，如果我使用WMI类创建vNIC，则不会获得Msvm_EthernetPortAllocationSettingData的实例，但是如果手动分配vNIC，则会被创建。.我也难以通过WMI创建Msvm_EthernetPortAllocationSettingData。
从下面的代码中，我得到4096的ReturnValue，这意味着该方法已执行..但未分配任何VLAN。
ManagementPath syntheticAdapterSettingDataC = new ManagementPath("Msvm_EthernetSwitchPortVlanSettingData");
String syntheticVlanAdapterId = String.Format("{0}\\C\\952C5004-4465-451C-8CB8-FA9AB382B773\\{1}", adapter.GetPropertyValue("InstanceID"), Guid.NewGuid());
ManagementClass syntheticAdapterClassC =
new ManagementClass(scope, syntheticAdapterSettingDataC, objectOptions)
{
["AccessVlanId"] = 55,
["Caption"] = "Ethernet Switch Port VLAN Settings",
["Description"] = "Represents the vlan setting data.",
["ElementName"] = "Ethernet Switch Port VLAN Settings",
["InstanceID"] = syntheticVlanAdapterId,
["NativeVlanId"] = 0,
["OperationMode"] = 1,
["PrimaryVlanId"] = 0,
["PruneVlanIdArray"] = null,
["PvlanMode"] = 0,
["SecondaryVlanId"] = 0,
["SecondaryVlanIdArray"] = null,
["TrunkVlanIdArray"] = null,
};
var syntheticAdapterC = syntheticAdapterClassC.CreateInstance();
ManagementPath VirtualEthernetSwitchManagementServicePath= new ManagementPath("Msvm_VirtualEthernetSwitchManagementService");
ManagementClass VirtualEthernetSwitchManagementServiceClass = new ManagementClass(scope, VirtualEthernetSwitchManagementServicePath, objectOptions);
ManagementBaseObject inParams = VirtualEthernetSwitchManagementServiceClass.GetMethodParameters("AddFeatureSettings");
string queryFeature = string.Format("select * from Msvm_FeatureSettingData Where InstanceID = 'Microsoft:Definition\\\\952C5004-4465-451C-8CB8-FA9AB382B773\\\\Default'");
ManagementObjectSearcher searcherFeature = new ManagementObjectSearcher(scope, new ObjectQuery(queryFeature));
ManagementObjectCollection features = searcherFeature.Get();
ManagementObject feature = null;
foreach (ManagementObject instance in features)
{
feature = instance;
break;
}
string[] syntheticAdapterSettingsC = new string[1];
syntheticAdapterSettingsC[0] = syntheticAdapterC.GetText(TextFormat.CimDtd20);
inParams["AffectedConfiguration"] = feature.GetText(TextFormat.CimDtd20);
inParams["FeatureSettings"] = syntheticAdapterSettingsC;
ManagementObject service = null;
foreach (ManagementObject instance in VirtualEthernetSwitchManagementServiceClass.GetInstances())
{
service = instance;
}
ManagementBaseObject vlanOut = service.InvokeMethod("AddFeatureSettings", inParams, null);

经过实验，我找到了答案。您需要执行的操作是使用“ Msvm_VirtualSystemManagementService ”类使用“ AddResourceSettings”方法创建（ Msvm_EthernetPortAllocationSettingData ）实例（如果已经拥有，则指向一个实例）。
要使用“ AddResourceSettings”方法，您需要定义：
现在您可以分配VLAN了。您将需要使用 Msvm_VirtualSystemManagementService 类和“ AddFeatureSettings”方法来创建 Msvm_EthernetSwitchPortVlanSettingData 的实例。
要使用“ AddFeatureSettings”方法，您需要定义：
就是这样。
干杯！

ya ..知道它有点旧，但是让其他尝试实现此目标的人省去了头痛。以下代码将网络适配器分配给VM并设置VLAN。请记住，我的“ _dataFields”是具有虚拟机数据的结构，因此您在这里只需更改几下即可。
添加新的网络适配器并设置VLAN

将交换机分配给VM的原始代码来自https://github.com/microsoft/Windows-classic-samples/blob/1d363ff4bd17d8e20415b92e2ee989d615cc0d91/Samples/Hyper-V/Networking/cs/ConnectVmToSwitch.cs，我刚刚对其进行了扩展以支持VLAN的使用。我没有任何参数在通话中，因为所有数据都在结构中。

从VM上的网络适配器删除VLAN

using (ManagementObjectCollection findConnections = NetworkUtils.FindConnections(virtualMachine, _dataFields._scope))
{
if (findConnections.Count > 0)
{
foreach (ManagementObject connection in findConnections)
{
// Get network adapter on virtual machine
using (ManagementObjectCollection vmSwitches = connection.GetRelated("Msvm_SyntheticEthernetPortSettingData"))
{
if (vmSwitches.Count > 0)
{
foreach (ManagementObject vmSwitch in vmSwitches)
{
if (vmSwitch["ElementName"].ToString() == _dataFields.NetworkAdapterName)
{
// Get vlan settings data from network adapter
using (ManagementObjectCollection vmSwitcheVLANs = connection.GetRelated("Msvm_EthernetSwitchPortVlanSettingData"))
{
if (vmSwitcheVLANs.Count > 0)
{
// Get first objecz
using (ManagementObject vlanData = WmiUtils.GetFirstObjectFromCollection(vmSwitcheVLANs))
{
using (ManagementBaseObject inParams = managementService.GetMethodParameters("RemoveFeatureSettings"))
{
// Remove it
inParams["FeatureSettings"] = new string[] { vlanData.Path.Path };
using (ManagementBaseObject outParams = managementService.InvokeMethod("RemoveFeatureSettings", inParams, null))
{
WmiUtils.ValidateOutput(outParams, _dataFields._scope);
}
}
}
}
}
}
}
}
}
}
}
}
}
请记住，我不使用通用的网络适配器名称，而是在创建VM时使用个性化的适配器名称。这样，我可以在需要时轻松获取适配器数据。
想要为适配器添加个性化名称的用户可以编辑AddSyntheticAdapter（ManagementObject virtualMachine，ManagementScope范围）函数，并在adapterToAdd [“ ElementName”]对象中包含其他名称。
希望这可以帮助勇敢地通过WMI发展的灵魂！ ：）
