how to use class attributes

Question

in .net languages a class can have "attributes"... I have one, that has this attribute

[System::Runtime::InteropServices::GuidAttribute("7F7CD0DB-91EF-49dc-9FA9-02D128515DD4")]

... I need this value in my code. How can I access it in the C++/CLI language? MyClass[GuidAttribute]? MyClass:GuidAttribute? [GuidAttribute]MyClass? how is the syntax? ... I've no idea...

Check an idea:

[System::Runtime::InteropServices::GuidAttribute("7F7CD0DB-91EF-49dc-9FA9-02D128515DD4")]
ref class MyClass1
{

};

. . .

using namespace System::Runtime::InteropServices;

auto type = MyClass1::typeid; // or 'obj->GetType( )' if you have an object
auto attribututes = type->GetCustomAttributes( GuidAttribute::typeid, false);

if( attribututes->Length > 0)
{
    auto attribute = (GuidAttribute^)attribututes[0];

    String^ guid = attribute->Value;

    // the Guid attribute was found

}
