  • .Net MVC3.0数据验证之伙伴类的使用

    
    
    // 使用EF的时候如果修改数据库重新生成EF里的model会被覆盖,写在上面的验证规则也会被覆盖,所以用伙伴类,创建强类型视图指向 UserInfo  model 

    using
    System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel.DataAnnotations; namespace MvcApp.Models {
    public class UserInfoValidate { [Required(ErrorMessage="编号不能为空")] public int ID{ get; set; } [Required(ErrorMessage="用户名不能为空")] public string UserName { get; set; } } [MetadataType(typeof(UserInfoValidate))] public partial class UserInfo { }
    
    
    }
