.net MVC中后台传前台的多种传值方式

标签：多个参数 tun http action 用户密码 gif png out head PS：一个Home控制器里两个Action方法Index和Temp 分别对应两个视图； Index页面用于显示单个参数传值 Temp页面用于显示多个参数参数 (项目命名空间：MVC多种传值方式) 两个类： Student : public int stuId { get; set; } public string stuName { get; set; } public int stuAge { get; set; } public char stuSex { get; set; } public string stuEmail { get; set; } User : public int uId { get; set; } public string uName { get; set; } public string uPwd { get; set; } 后台Index方法(后台传递单个参数的几种方法)： Index页面: 后台Temp方法（传递多个参数的几种方法）： Temp页面： .net MVC中后台传前台的多种传值方式 标签：多个参数 tun http action 用户密码 gif png out head 原文地址：https://www.cnblogs.com/licm/p/12382116.html
