}示例2: BindInvokeMember
public override DynamicMetaObject BindInvokeMember(InvokeMemberBinder binder, DynamicMetaObject[] args) {

// ? result
// : TryGetMember(payload, out result)
// ? FallbackInvoke(result)

// Then it calls FallbackInvokeMember with this tree as the
// "error", giving the language the option of using this
// tree or doing .NET binding.
