使用保存的會話變量讀取和設置變量

Question

我將用戶名，角色和用戶ID添加到會話中，並且會話保存在SQL Server中。如果用戶在會話尚未過期時關閉並重新打開瀏覽器，那麼如何獲取添加到會話中的先前值？ 例如，會話中添加了以下值。

SessionWrapper.currentRequest.UserName = model.UserName; 
     SessionWrapper.currentRequest.Role = aRole; 
     SessionWrapper.currentRequest.UserId = userId; 

用戶關閉瀏覽器並重新打開它;該會話未過期。如何恢復會話以便這些變量保持不變？

//This is the object that is wrapped in the session

public class CurrentRequest 
    { 
     public int UserId { get; set; } 
     public string Role { get; set; } 
    } 

//The session Wrapper

public class SessionWrapper 
      { 
       public static CurrentRequest currentRequest 
       { 
        get 
        { 
         if (HttpContext.Current.Session["request"] != null) 
         { 
          return (CurrentRequest)HttpContext.Current.Session["request"]; 
         } 
         else 
         { 
          return null; 
         } 
        } 
        set 
        { 
         HttpContext.Current.Session["request"] = value; 
        } 
       } 
      } 

// I am saving the following values in the session

SessionWrapper.currentRequest.UserName = model.UserName; 
    SessionWrapper.currentRequest.Role = aRole; 
    SessionWrapper.currentRequest.UserId = userId; 

The sessionState mode is SQLServer, and I can see data added to the both ASPSTATE tables. here is how I set up the session state in the config file

<sessionState mode="SQLServer" allowCustomSqlDatabase="true" timeout="60" 

cookieless="false" sqlConnectionString="Data Source=(****);Initial Catalog=data1;UserID=****;Password=****;Integrated Security=True" />

我沒有在我的Global.asax文件一個在session_start和Session_End中的方法。我加了一個，問題就消失了。
