When applied to a class definition, ensures that a private class returns a valid name from the GetRuntimeClassName function..
[Platform::Metadata::RuntimeClassName] name name
The name of an existing public type that is visible in the Windows Runtime.
Use this attribute on private ref classes to specify a custom runtime type name and/or when the existing name does not meet the requirements. Specify as a name a public interface that the class implements.
The following example shows how to use the attribute. In this example, the runtime type name of HellowWorldImpl is Test::Native::MyComponent::IHelloWorld
namespace Test
{
namespace Native
{
namespace MyComponent
{
public interface class IHelloWorld
{
Platform::String^ SayHello();
};
private ref class HelloWorldImpl sealed :[Platform::Metadata::RuntimeClassName] IHelloWorld
{
public:
HelloWorldImpl();
virtual Platform::String^ SayHello();
};
Platform::String^ HelloWorldImpl::SayHello()
{
return L"Hello World!";
}
}
}
}
