推荐答案

您可以编写一个自定义验证属​​性，并用它装点你的模型：

You could write a custom validation attribute and decorate your model with it:

[AttributeUsage(AttributeTargets.Class)]
public class AtLeastOnePhoneAttribute: ValidationAttribute
{
    public override bool IsValid(object value)
    {
        var model = value as SomeViewModel;
        if (model != null)
        {
            return !string.IsNullOrEmpty(model.Phone1) ||
                   !string.IsNullOrEmpty(model.Phone2);
        }
        return false;
    }
}

和则：

[AtLeastOnePhone(ErrorMessage = "Please enter at least one of the two phones")]
public class SomeViewModel
{
    public string Phone1 { get; set; }
    public string Phone2 { get; set; }
}

有关更高级的验证场景你可能看看 FluentValidation.NET 或的万全

For more advanced validation scenarios you may take a look at FluentValidation.NET or Foolproof.
