Question

我的模型看起来像

public class MPariData : IValidatableObject
{
    public int moneyObtain { get; set; }
    public string IBAN { get; set; }

    public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
    {
        var fields = new[] { "IBAN" };

        if (moneyObtain == 2)
        {
            yield return new ValidationResult("Required field" ,fields);
        }
    }
}

如果需要moneyObtains == 2，IBAN字段，我想要。我的观点如下：

<div class="col-lg-10">
    @Html.TextBoxFor(model => model.IBAN, new { @class = "form-control" })
    @Html.ValidationMessageFor(model => model.IBAN)
</div>

但没有成功。我的验证消息没有出现，而且我的控制器ModelState始终有效。

有什么想法吗？

我试过这个，它有效：对于模型：

    public int moneyObtain { get; set; }
    public string IBAN { get; set; }

   public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
    {
        List<ValidationResult> result = new List<ValidationResult>();

        if (moneyObtain == 2)
        {
            result.Add(new ValidationResult("Required field", new string[] { "IBAN" }));  
            return result;
        }

...

对于视图： ....

 <tr>
      <td>@Html.LabelFor(m => m.moneyObtain)</td>
      <td>@Html.EditorFor(m => m.moneyObtain)</td>
      <td>@Html.ValidationMessageFor(m => m.moneyObtain)</td>
 </tr>
 <tr>
      <td>@Html.LabelFor(m => m.IBAN)</td>
      <td>@Html.EditorFor(m => m.IBAN)</td>
      <td>@Html.ValidationMessageFor(m => m.IBAN)</td>
 </tr>

...

IValidatableObject的MVC Validate函数不起作用
