)

 

But When I am Trying to use This Session in Another Action Mehtod Then I am Getting Null value . i have allready Rnd on this topic but I am find nothing in google

if (Session["Game"] != null)
{
test = true;
}
PlayGame = (Players)Session["Game"];

Please give me a suggestion for That How to fix this issue

 

Here is My Code:-

 

1. > Code Where I am Creating Session

public ActionResult EnterGame(Players Players)
{
if (!(string.IsNullOrEmpty(Players.FirstPlayer) && string.IsNullOrEmpty(Players.SecondPlayer)))
{
Players Game = new Players();
Players.DefaultPlayer = Players.FirstPlayer;
Game = Players;
Session["Game"] = Game;
bool test;
if (Session["Game"] != null)
{
test = true;
}
return View("PlayGame", Game);
}
else
{
ModelState.AddModelError(string.Empty, "Both Players Name,s Are Required");
return View("Index", Players);
}
}

###### Code Where I am use Session to initilize The Session Data

public ActionResult PlayGame(int index) {
Players PlayGame = new Players();
bool test;
if (Session["Game"] != null)
{
test = true;
}
PlayGame = (Players)Session["Game"];
PlayGame Game = new PlayGame();
Game.Play(index, PlayGame);
if (Game.IsWon == true)
{
var Result = new { Message = Game.Message, IsWon = Game.IsWon, AssignedValue = Game.AssignedValue };
return Json(Result, JsonRequestBehavior.AllowGet);
}
else
{
var Result = new { Message = Game.Message, DefaultPlayer = PlayGame.DefaultPlayer, AssignedValue = Game.AssignedValue };
return Json(Result, JsonRequestBehavior.AllowGet);
}
}
