.NET doesn't provide a method to reflect the immediate interface ancestors of a given type, this method accomplishes that.
Raw
GetClosestInterfaces.cs
private IEnumerable<Type> GetClosestInterfaces(Type type)
{
IEnumerable<Type> interfaces = type.GetInterfaces();
var parents = interfaces.Except(
interfaces.SelectMany(x => x.GetInterfaces()).Intersect(interfaces));
return parents;
}
