如何在ASP.NET MVC4中显示两个不同的错误消息

Question

我想显示两条不同的错误消息。首先给出Int64值的必需值和秒值。这是我的代码。

    [Display(Name = "Employee")]
    [Required]
    public Int64 EmployeeId { get; set; }

Answer 1

您可以使用RangeAttribute。

[Required(ErrorMessage = "Msg1")]
[Range(10, 1000, 
    ErrorMessage = "Value for {0} must be between {1} and {2}.")]
public object Weight;

Answer 2

您可以在此处使用数据注释扩展：http://dataannotationsextensions.org/

然后按如下方式添加两个注释：

[Required(ErrorMessage = "Employee Id is required")]
[DataAnnotationsExtensions.Integer(ErrorMessage = "Please enter a valid number.")]
public Int64 EmployeeId { get; set; }
