Question

我一直在研究为我的Web App设置会话变量以存储登录用户信息的方法。我已经取得了很大的进步，作为一个新手，但我很难过为什么设置变量将设置所有这些而不仅仅是指定的变量。有人可以指出我的错误吗？谢谢!!

    }

我认为您没有正确设置会话密钥。在你的静态类中，你有一个属性设置器，它基本上是会话Session [“”] =所有成员的一些值。您不需要将密钥设置为.net 3.5中私有成员的名称，甚至不需要私有成员。您也可以填充整个会话对象，而不用担心每个成员。

然后只需访问属性的当前实例化器，如

MySession.Current.UserName="guest";


public class MySession
{
    private const string _SessionName = "__MY_SESSION__";
    //--------------------------------------------------------------------------------------------
    private MySession(){}
    //--------------------------------------------------------------------------------------------
    public static MySession Current
    {
        get
        {
            MySession session =
                (MySession)HttpContext.Current.Session[_SessionName];
            if (session == null)
            {
                session = new MySession();
                session.Property1 = new Property1();
                session.Property2 = new Property2();
                session.UserName = "";
                HttpContext.Current.Session[_SessionName] = session;
            }
            return session;
        }
    }
    public string UserName { get; set; }
    public Property1 Property1 { get; set; }
    public Property2 Property2 { get; set; }
}

在类中设置会话变量是设置所有这些，而不仅仅是一个
