Question

的ViewModels

[Display(Name = "Purchase limit")]
[Required]
public Dictionary<int, int> DownloadLimit { get; set; }

查看

@foreach (var downloadLimit in Model.DownloadLimit)
{
    @Html.TextBoxFor(m => m.DownloadLimit[downloadLimit.Key], new { @class = "form-control mb10", @type = "number"})
}

我的字典有密钥，值都是整数。当我将字符串输入到文本框时，显示消息错误：“字段Int32必须是数字”。

我如何将此邮件自定义为“下载限制必须为数字”
如何添加RangeAttribute以验证所有值必须在特定范围内。

RangeAttribute在Dictionary中不起作用。我试过了：

[Range(0,99999999, ErrorMessage = "Download Limit must be a number in range from 0 to 99999999")]
public Dictionary<int, int> DownloadLimit { get; set; }

任何人都可以建议我这样做，我非常喜欢不使用自定义属性的解决方案。

谢谢！

Answer 1

 [Range(typeof(int), "0", "9999", ErrorMessage = "{0} must be a decimal/number between {1} and {2}.")]

或

[Range(typeof(decimal), "0", "9999", ErrorMessage = "{0} must be a decimal/number between {1} and {2}.")]
