Asp.Mvc 2.0用户登录实例讲解---(2)用户登录与注销(5)

        [HttpPost]
        public ActionResult Login(Models.Login model)
        {
            if (new Models.SqlHelper().UserLogin(model))
            {
                //如果用户名存在，转向主页
                FormsService.SignIn(model.UserName,model.RememberMe);
                return RedirectToAction("index");
            }
            else
            {
                //登录失败，转向登录页面
                ViewData["msg"] = "登录失败";
                return View(model);
            }

       
        }

第二个Login方法前面有HTTPPOST属性，所以只能接受POST请求

4.SQLHELPER中添加判断用户名和密码的方法
[csharp]  /// <summary>  
        /// 判断用户登录是否成功  
        /// </summary>  
        /// <param name="model"></param>  
        /// <returns></returns>  
        public bool UserLogin(Login model) 
        { 
            strUserExist = string.Format(strUserExist, model.UserName, model.UserPwd);
