我可以为MVC中的所有操作结果创建一个会话 [英] Can I have one session for all action result in MVC

问题描述

我正在研究MVC并创建了一个会话来检查登录。我创建了一个会话，并且在索引操作上已经应用了身份验证。



只是想要对索引的所有操作结果做同样的事情。我可以为单个会话检查创建一个代码，说Session [LoginUserName]并检查多个ActionResults的值。



我尝试过：



尝试使用单个actionresult创建会话检查

I Was working on MVC and created a session just to check for Login. I have created a session and on Index action have applied the authentication.

Just Wanted the do same thing with all the action results with Index. Can I create a single code for single session check say "Session[LoginUserName]" and check the value for multiple ActionResults.

What I have tried:

推荐答案

You need to call them either in the constructor or in a method of your controller.

Furthermore those variables should have been set somewhere or their vaues will stay null.

According to your example you will need to set your Session["SessionClass"] key somewhere before calling it in the constructor:

public ActionResult Details()
{
  Session["SessionClass"] = new MyClass() { // Set your class properties };

  return View((MyClass)Session["SessionClass"]);
}
Now we will unbox that saved value from the session:

public HomeController()
{
  MyClass test = (MyClass)Session["SessionClass"];

  // Do stuff with `test` now
}
This should work fine within your controller.
