Here is a Example. Say we want to manage session after checking user validation, so for this demo only I am hard coding checking valid user. On account Login
这是一个例子。假设我们想在检查用户验证后管理会话，所以对于这个演示，我只是硬编码检查有效用户。在帐户登录
public ActionResult Login(LoginModel model)
{
if(model.UserName=="xyz" && model.Password=="xyz")
{
Session["uname"] = model.UserName;
Session.Timeout = 10;
return RedirectToAction("Index");
}
}
On Index Page
在索引页上
public ActionResult Index()
{
if(Session["uname"]==null)
{
return Redirect("~/Account/Login");
}
else
{
return Content("Welcome " + Session["uname"]);
}
}
On SignOut Button
在退出按钮上
Session.Remove("uname");
return Redirect("~/Account/Login");
