Data Annotaions(Model 验证）

Model验证

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Threading.Tasks;

namespace WebApplication3.Models
{
    public class Movie
    {
        public int Id { get; set; }

        [Required]
        [StringLength(100)]
        public string Title { get; set; }

        [DataType(DataType.Date)]
        public DateTime ReleaseDate { get; set; }

        [Required]
        [StringLength(1000)]
        public string Description { get; set; }

        [Range(0,999.99)]
        public decimal  Price { get; set; }


    }
}
  • [CreditCard]
  • [Compare]
  • [EmailAddress]
  • [Phone]
  • [Range]
  • [RegularExpression]
  • [Required]
  • [StringLength]
  • [Url]
  • [Display]
  • [DataType(DateType=)]

防止跨站请求伪造验证

使用[ValidateAntiForgeryToken]

  public class HomeController : Controller
    {
        [HttpPost]
        [ValidateAntiForgeryToken]
        public IActionResult Index(int id)
        {

            StudentsViewModel svm = new StudentsViewModel();
            var s= svm.GetStudentById(id);
            if(s==null)
}
}

界面显示验证问题

显示单个错误信息

  <span asp-validation-for="@Model.FirstName"></span>

验证信息提示汇总

  <div asp-validation-summary="All"></div>
