asp.net-mvc - 禁用 ASP.NET MVC 验证

Question

我的 asp.net mvc 应用程序中有一个简单的 ViewModel 类。

public class DestinationViewModel
{
     [Display(Name = "Country")]
     [some validation attributes]
     public string CountryName { get; set; }

     [Display(Name = "Destination")]
     [some validation attributes]
     public string DestinationName { get; set; }

     public DateTime? DepartureDate { get; set; }

     public DateTime? ArrivalDate { get; set; }
}

当我将数据传递给控制器时，我的应用程序显示无效出发和到达日期的验证错误。但我不想要这样的行为。有什么方法（属性）可以仅在DepartureDate和ArrivalDate字段上禁用验证？

The MVC data binder will attempt to convert which ever value you put in your input field to it's corresponding ViewModel type. In your scenario, you are passing "21321" which obviously isn't going to work as it's not valid Date/Time.

Either pass a valid DateTime string value or leave it empty (as the field is nullable).

Tip - It's usually a good idea from a users point of view to make date fields readonly and provide a date picker of some sort to avoid issues with manually entering valid date formats.
