如何在mvc 3中从一个控制器访问一个会话变量到另一个控制器 [英] how to access a session variable from one to another controller in mvc 3
问题描述
以下代码在我的一个控制器中
var model1 = new Book（）;
model1.id = 1;
model1.BookName =Life Life;
model1.Author =Kate Atkinson;
model1.Classification =Fiction;
model1.Price =CND $ 19.95;
Book model2 = new Book（）;
model2.id = 2;
model2.BookName =River of Stars;
model2.Author =Guy Gavriel Kay;
model2.Classification =小说;
model2.Price =CDN $ 32.00;
Book model3 = new Book（）;
model3.id = 3;
model3.BookName =Light;
model3.Author =迈克尔格兰特;
model3.Classification =JUVENILE;
model3.Price = CDN $ 20.99
List< book> list = new List< book>（）;
list.Add（model1）;
list .Add（model2）;
list.Add（model3）;
list.Add（model4）;
list.Add（model5） ;
会话[var] =列表;
返回查看（列表）;
我想访问另一个控制器中的相同列表而不对同一列表进行硬编码。会话变量不起作用......它返回null。我如何实现这一目标？我的语法错了吗？我是mvc 3的新手PLZ给我一个具体的解释
谢谢
following code is in one of my controller
var model1 = new Book();
model1.id = 1;
model1.BookName = "Life After Life";
model1.Author = "Kate Atkinson";
model1.Classification = "Fiction";
model1.Price = "CND $ 19.95";
Book model2 = new Book();
model2.id = 2;
model2.BookName = "River Of Stars";
model2.Author = "Guy Gavriel Kay";
model2.Classification = "Fiction";
model2.Price = "CDN $32.00";
Book model3 = new Book();
model3.id = 3;
model3.BookName = "Light";
model3.Author = "Michael Grant";
model3.Classification = "JUVENILE";
model3.Price = "CDN $20.99"
List<book> list = new List<book>();
list.Add(model1);
list.Add(model2);
list.Add(model3);
list.Add(model4);
list.Add(model5);
Session["var"] = list;
return View(list);
I want to access the same list in another controller without hardcoding the same list. The session varible is not working ...it returns null. Do How do i achieve this? is my syntax is wrong?.. I''m new to mvc 3 plz give me a specific explanation
Thank you
