Error : a 'for each' statement cannot operate on an expression of type "MyKinect::ActionKeys []"

im very new in c# and c++. i wana convert C# codes into c++ but i got this error on "for each (auto key in keys)"line. do u mind tell me wat i did wrong. Many Thanx.

C# code :

Public InputResule GetKey(ActionKeys[] keys)
    {
        InputResule ir = new InputResule();

        foreach (var key in keys)
        {
            var data = mActionList.FirstOrDefault(p => p.Key == key);
            if (data.Value != MovementType.None)
            {
                ir = CheckMovement(data.Value);
            }
        }
        return ir;
    }

C++ Code :

InputResule KinectInput::GetKey(ActionKeys keys[])
{
    InputResule ir = InputResule();

for each (auto key in keys)
    {
        auto data = mActionList.find(key->first);
        {
            return p->Key == key;
        };
        if (data->Value != MovementType::None)
        {
            ir = CheckMovement(data->Value);
        }
    }
    return ir;
}
