ASP.NET MVC 2 - 属性验证 [英] ASP.NET MVC 2 - Property validation

问题描述

我是新来的MVC和有关于验证的问题。有没有办法动态设置错误信息？

I'm new to MVC and have a question regarding validation. Is there a way to dynamically set the Error Message?

例如，我怎么能实现以下（忽略硬$ C $ 50的CD，这可能来自于Web.config文件或者具体到当前登录）。

For example, how could I achieve the following (ignore the hardcoded 50, this could come from the Web.config or specific to the current logged).

[MetadataType(typeof(DocumentValidation))]
public partial class Document
{
    public class DocumentValidation
    {
        private const int MaxLength = 50;

        [Required(ErrorMessage = "Document Title is required")]
        [StringLength(MaxLength, ErrorMessage = "Must be under " + MaxLength.ToString() + " characters")]
        public string Title { get; set; }
    }

}

谢谢，

推荐答案

检查出的 IDataErrorInfo的以及这个问题我问了一下 IDataErrorInfo的与DataAnnotations

Check out IDataErrorInfo and this question I asked about IDataErrorInfo vs. DataAnnotations.
