如何在MVC中使用Annotations [英] How do I use Annotations in MVC

问题描述

我在视野中的代码是......



输入您的名字：@ Html.TextBoxFor（f => f.F_Name）



@ Html.ValidationMessageFor（m => m.F_Name）



输入姓氏：@ Html.TextBoxFor（l => ; l.L_Name）



@ Html.ValidationMessageFor（m => m.L_Name）



输入薪资：@ Html.TextBoxFor（s => s.sal）



@ Html.ValidationMessageFor（m => m.sal）



在模型中我写了这些代码行：

my code in view is ...

Enter Your First Name: @Html.TextBoxFor(f => f.F_Name)


@Html.ValidationMessageFor(m=>m.F_Name)

Enter Last Name: @Html.TextBoxFor(l => l.L_Name)


@Html.ValidationMessageFor(m=>m.L_Name)

Enter Salary: @Html.TextBoxFor(s => s.sal)


@Html.ValidationMessageFor(m=>m.sal)

and in model i have written these lines of code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.Web.Mvc;
using ProjectTemplate.Web.Infrastructure;

namespace ProjectTemplate.Web.Models
{
    public class validation
    {
        [Required(ErrorMessage = "The First Name field is required")]
        [Display(Name="Enter Your First Name:")]
         public  string F_Name { get; set; }

        [Required(ErrorMessage = "Last Name field is required")]
         public   string L_Name { get; set; }

        [Range(9000,12000,ErrorMessage="Salary Amount should be between 9k to 12k")]
        [DisplayName("Enter Your First Name:")]
         public int sal { get; set; }


    }
}

推荐答案

您是否检查控制器中的数据是否有效？检查此链接并查看 PersonController 中的创建方法：

祝你好运！

Do you check if the data is valid in your controller? Check this link and have a look at the Create method in PersonController:

Good luck!
