ENTER键的虚拟键代码是什么

我已经通过windows WMI实现了一个远程hyper-v管理类，但ENTER键的键代码是什么

该方法是"；按键"；并且该类是Hyper-V WMI类中的Msvm_ Keyboard

示例代码在Msvm_Keyboard类的PressKey方法中

上面示例中ENTER键的第二个参数是什么

根据虚拟密钥代码表；0"；或"；0x0D"；但这两种都不被这个样品所接受！

样本代码：

class PressKeyClass
{
    static ManagementObject GetComputerKeyboard(ManagementObject vm)
    {
        ManagementObjectCollection keyboardCollection = vm.GetRelated
        (
            "Msvm_Keyboard",
            "Msvm_SystemDevice",
            null,
            null,
            "PartComponent",
            "GroupComponent",
            false,
            null
        );
        ManagementObject keyboard = null;
        foreach (ManagementObject instance in keyboardCollection)
        {
            keyboard = instance;
            break;
        }
        return keyboard;
    }
    static void PressKey(string vmName, int keyCode)
    {
        ManagementScope scope = new ManagementScope(@"root'virtualization", null);
        ManagementObject vm = Utility.GetTargetComputer(vmName, scope);
        ManagementObject keyboard = GetComputerKeyboard(vm);
        ManagementBaseObject inParams = keyboard.GetMethodParameters("PressKey");
        inParams["keyCode"] = keyCode;
        ManagementBaseObject outParams = keyboard.InvokeMethod("PressKey", inParams, null);
        if ((UInt16)outParams["ReturnValue"] == ReturnCode.Completed)
        {
            string.Format("Key {0} was pressed on {1}", keyCode, vm["ElementName"]);
        }
        else
        {
            string.Format("Unable to press key {0}' on {1}", keyCode, vm["ElementName"]);
        }
        inParams.Dispose();
        outParams.Dispose();
        keyboard.Dispose();
        vm.Dispose();
    }
    static void Main(string[] args)
    {
        if (args != null && args.Length != 2)
        {
            Console.WriteLine("Usage: PressKey vmName keyCode");
            return;
        }
        string vmName = args[0];
        int keyCode = int.Parse(args[1]);
        PressKey(args[0], keyCode);
    }
}

ENTER键的虚拟键代码是什么

我发现了问题。输入键的代码"0x0D"是正确的，但Microsoft示例代码中存在错误。按第40行中Msvm_Keyboard类
的键方法：

if ((UInt16)outParams["ReturnValue"] == ReturnCode.Completed)

上面的铸造是不正确的，然后我认为虚拟钥匙代码是不正确。
