GetRuntimeClassName function (C++/WinRT)

A member function (of a generated implementation type) that returns a string containing the fully-qualified type name of the Windows Runtime class being implemented.

For an explanation of the implementation type and projected type concepts, see Consume APIs with C++/WinRT and Author APIs with C++/WinRT.

This is a member function of generated implementation types. To retrieve the runtime class name of any arbitrary IInspectable, use winrt::get_class_name. Also see the function that both methods are based on, which is IInspectable::GetRuntimeClassName.

Syntax

winrt::hstring GetRuntimeClassName() const;

Return value

A winrt::hstring containing the fully-qualified type name of the Windows Runtime class implemented by the implementation type.

Example

// MainPage.cpp
void winrt::MyProject::implementation::MainPage::f()
{
 winrt::hstring name = GetRuntimeClassName();
 assert(name == L"MyProject.MainPage");
}

You can implement ICustomPropertyProvider::Type like this.

Windows::UI::Xaml::Interop::TypeName Type()
{
 return Windows::UI::Xaml::Interop::TypeName{ GetRuntimeClassName() };
};

Or you can use the winrt::xaml_typename function template.

Requirements

Minimum supported SDK: Windows SDK version 10.0.17134.0 (Windows 10, version 1803)

Tool: cppwinrt.exe
