如何更改在ASP.NET MVC INT模型验证的ErrorMessage？ [英] How to change the ErrorMessage for int model validation in ASP.NET MVC?

问题描述

我有这样定义的属性的模型：

I have a model with a property defined like this:

    [Required(ErrorMessage="Please enter how many Stream Entries are displayed per page.")]
    [Range(0,250, ErrorMessage="Please enter a number between 0 and 250.")]
    [Column]
    public int StreamEntriesPerPage { get; set; }

这工作，除非用户输入类似100Q。然后会显示一个比较难看的错误，说：值'100Q'是无效的StreamEntriesPerPage。

This works unless the user enters something like "100q". Then a rather ugly error is displayed that says "The value '100q' is not valid for StreamEntriesPerPage."

有没有我可以用它来覆盖默认的错误消息，当输入不是一个int属性？

Is there an attribute I can use to override the default error message when input is not an int?

推荐答案

是的，你可以使用数据注解扩展时，标记您的属性作为以下内容：

Yes, you can use Data annotations extensions, mark your property as the following:

[Required(ErrorMessage = "Please enter how many Stream Entries are displayed per page.")]
[Range(0, 250, ErrorMessage = "Please enter a number between 0 and 250.")]
[Column]
[DataAnnotationsExtensions.Integer(ErrorMessage = "Please enter a valid number.")]
public int StreamEntriesPerPage { get; set; }
