将 Session 变量从一个 controller 传递到另一个

Question

我为用户登录创建了一个 session：

[HttpPost]
public ActionResult Index(UserLogin lc)
{
    string mainconn = ConfigurationManager.ConnectionStrings["DBConnection"].ConnectionString;
    SqlConnection sqlconn = new SqlConnection(mainconn);
    SqlCommand sqlcomm = new SqlCommand("UserLogin");
    sqlconn.Open();
    sqlcomm.Connection = sqlconn;
    sqlcomm.CommandType = CommandType.StoredProcedure;
    sqlcomm.Parameters.AddWithValue("@Email", lc.Email);
    sqlcomm.Parameters.AddWithValue("@Password", lc.Password);
    SqlDataReader sdr = sqlcomm.ExecuteReader();
    
    if(sdr.Read())
    {
        FormsAuthentication.SetAuthCookie(lc.Email, true);
        Session["Email"] = lc.Email.ToString();
        return RedirectToAction("Welcome");
    }

现在我需要使用存储在另一个 controller 中的 Session 变量。 我该怎么做？

Session Variable works with HTTP Request you'll get the session variable in any controller inherited from BaseController after once you have set the Session variable key value.As Session is a Dictionary Type Object.
