ASP.NET：是否可以保持复杂的对象，如表＆LT;＆GT;是会话？ [英] ASP.NET: Is it possible to keep complex object such as list<> is the session?

问题描述

ASP.NET：是否有可能保持复杂的对象，如列表＆LT;对象＆gt; 是会话？如果是的话，该怎么办呢？我试图保持会话列表，但我被告知，我不能在列表转换为字符串。

ASP.NET: Is it possible to keep complex object such as List<object> is the session? If yes, how to do so? I'm trying to keep a list in the session, but I'm being told that I cannot convert that List to a string.

[Serializable]
public class Client
{
        public string ClientType { get; set; }
        public string ClientName { get; set; }
        public string SubClientName { get; set; }
        public string Project { get; set; }
        public string Service { get; set; }
        public string Activity { get; set; }
}
List<Client> ListOfClients;
protected void Page_Load(object sender, EventArgs e)
{
     if(!IsPostBack)
     {
        ListOfClients = new List<Client> { new Client()}; 
        Session["ListOfClients"] = ListOfClients;//This is where the error occurs
                                                 //Cannot convert List<Client> to string... 
     }  
}

有许多操作来执行，但这个想法是让无论是在客户端的会话列表中。

There are many operations to execute, but the idea is to keep whatever is in the list of clients in the session.

感谢您的帮助。

推荐答案

是的，你可以存储任何序列化对象成一个会话变量。例如：

Yes, you can store any serializable object into a session variable. For example:

List<string> list;

Session["list"] = list;

然后返回值：

List<string> list = (List<string>)Session["list"];
