asp.net-mvc – 地址字段的自定义ASP.NET MVC验证摘要

public class Address
{
    public string Street { get; set; }
    public string City { get; set; }
    public string Zip { get; set; }
}

public class Order
{
    [Required]
    public string FirstName { get; set; }

    [Required]
    public string LastName { get; set; }

    [AddressRequired("Your shipping address is incomplete")]
    public Address ShipTo { get; set; }

    [AddressRequired("Your billing address is incomplete")]
    public Address BillTo { get; set; }

    // you could do this if you still need 1:1 mapping for model binding
    public string ShippingCity
    {
        get { return ShipTo.City; }
        set { ShipTo.City = value; }
    }
}

验证属性看起来像这样：

public class AddressRequiredAttribute : ValidationAttribute
{
    ...

    public override bool IsValid(object value)
    {
        var address = value as Address;

        if (address != null)
        {
            ...
        }
    }
}
