public static IBFFPay getInstanceNew(string libname, string nameplaces = "api.Interfaces")
{

Core.Ibffpay = (IBFFPay)Activator.CreateInstance(Type.GetType(string.Format(libname + ","+ nameplaces, new object[0]), false, true));//Type.GetType 完整的类名地址，命名空间
return Core.Ibffpay;
}

Type.GetType  可以获取到对应类的实现 返回到接口
