ASP.NET MVC 中的会话变量

Question

I need to create something like a session variable in .net MVC. I'm using ViewData. First I set it in my Controller Index:

public ActionResult Index(int id)
    {
        ViewData["myID"] = id;
    }

Then, I'll need to use it in another function of the same controller. However, I have to send it to my view. Store the data into a . Then read it again. View:

<input type="hidden" id="myID" name="myID" value='@ViewData["myID"]'  />

Other function of the controller where I get the id:

[HttpPost, ValidateInput(false)]
    public ActionResult Test(FormCollection form)
    {
        var pId = form["myID"];
    }

It works, but looks wrong (I'm new in .net mvc). Is there a way where I can set this id one time in my controller and then read/get it when I need?

Thanks

try this

for set

System.Web.HttpContext.Current.Session["Id"] = 1;

for get

var id=Convert.ToInt32(System.Web.HttpContext.Current.Session["Id"]);
