Nếu bạn cần bất kỳ thông tin khác xin vui lòng cho tôi biết, nhờ

Answer 1

Bạn có một không cần thiết { trong PostalCode nhắn RequiredAttribute 's lỗi của bạn:

[Required(ErrorMessage = "Please enter {Postal Code")] 

xóa nó và nó sẽ hoạt động.

Bạn có ngoại lệ vì khung sử dụng ErrorMessage làm format string và với một khung không được đính kèm { điều này không hợp lệ.
