因为对.net了解不是太深入，所以只能做出这样的水平：

找到要查找的反射属性信息：
    PropertyInfo^ getPropertyInfo(Type^ t, String^ pName) {
        PropertyInfo^ pInfo;
        while (t != nullptr) {
            pInfo = t->GetProperty(pName, BindingFlags::DeclaredOnly | BindingFlags::Public | BindingFlags::Instance);
            if (pInfo != nullptr)
            {
                return pInfo;
            }
            t = t->BaseType;
        }
        return nullptr;
    }

从一个Component开始查找，然后查找其子Component是否有名为compName的控件，有则返回，无则返回nullptr
    // get a component by it's name, the component is in comp
    Component^ getComponentByName(String^ compName, Component^ comp) {
        if (nullptr == comp)
        {
            return comp;
        }

        // if this component is the right one, then return it
        Type^ t = comp->GetType();
        PropertyInfo^ pInfo = t->GetProperty("Name");
        if (pInfo != nullptr && compName->Equals(dynamic_cast<String^>(pInfo->GetValue(comp, nullptr))))
        {
            return comp;
        }

        // search this component's children Controls
        Component^ retComp;
        pInfo = getPropertyInfo(t, "Controls");
        if (pInfo != nullptr)
        {
            System::Collections::IList^ list = safe_cast<System::Collections::IList^>(pInfo->GetValue(comp, nullptr));
            if (list != nullptr)
            {
                for (int i = 0; i < list->Count; i++)
                {
                    if (nullptr != (retComp = getComponentByName(compName, safe_cast<Component^>(list[i]))))
                    {
                        return retComp;
                    }
                }
            }
        }

        // search this component's children Items
        pInfo = getPropertyInfo(t, "Items");
        if (pInfo != nullptr)
        {
            System::Collections::IList^ list = safe_cast<System::Collections::IList^>(pInfo->GetValue(comp, nullptr));
            if (list != nullptr)
            {
                for (int i = 0; i < list->Count; i++)
                {
                    if (nullptr != (retComp = getComponentByName(compName, safe_cast<Component^>(list[i]))))
                    {
                        return retComp;
                    }
                }
            }
        }

        return nullptr;
    }
