why the Interfaces property of INamedTypeSymbol，return all the interfaces result witch is same as AllInterfaces property

[MarvelTiter]

the code maybe like this，IWrapHello interface's INamedTypeSymbol

public interface IHello
{
}

public interface IHello<T>: IHello
{
}

public interface IWrapHello: IHello<int>
{
}

// IWrapHello 
INamedTypeSymbol symbol ;
// symbol.Interfaces == symbol.AllInterfaces  why?

Interface inheritance does not work like class inheritance. Interfaces directly implement all interfaces that were inherited from any base interfaces.

if I need to recursively handle interface inheritance, are there other way to achieve this?

Why do you need to do that?
