Asp.net mvc 自定义服务器端验证

使用了系统自带的服务器端验证方式，尝试编辑自己的验证方式

1、创建新类TeacherAgeValidation

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;
namespace Mvc_一.Models
{
    public class TeacherAgeValidation:ValidationAttribute
    {
        protected override ValidationResult IsValid(object value, ValidationContext validationContext)
        {
            if (value == null)
            {
                return new ValidationResult("Please input Id");
            }
            else
            {
                if (!value.ToString().Contains("1001"))
                    return new ValidationResult("Id should contain 1001");
            }
            return ValidationResult.Success;
        }
    }
}  

2、在Teacher中添加到TeacherAge前面

 [TeacherAgeValidation]
 public int TeacherAge { get; set; }

3、测试运行
