推荐答案

更改代码以处理错误情况：

Change your code to handle the error case as:

protected void Page_Load(object sender, EventArgs e)
{
   if(Session["UserName"] != null)
     lblUser.Text = Session["UserName"].ToString();
   else
     Response.Redirect("SessionTimeoutMessagePage.aspx");
}

你的问题可能是会话超时。

在这种情况下你应该恢复你的会话参数和在任何情况下，如果会话参数存在，或者会话存在，你最好使用会话参数检查。



会话[ mySessParam] == null

如果以上是 True ，则表明会话已经结束（或者代码中的某个地方）已经删除了参数。



注意： 您可以配置会话超时 web.config文件超过默认的20分钟。

Your problem is probably that the session timed out.
In this case you should revive your session parameters and in any case you''d better use a check for the session parameter if it exists, or if the session exists.

Session["mySessParam"] == null
If the above is True, it indicates that the session has ended (or that somewhere in your code you''ve removed the parameter).

NOTE: you can configure the session timeout in your web.config file to be more than the default 20 mins.

正如Edo Tzumer所说问题似乎是会话timeoutout。你可以从web.config维护你的会话时间。



类似的事情可以通过配置< b> IIS 上的会话状态设置，您可以在其中简单地输入会话超时时间或为您的应用选择更合适的会话模式。

As stated by Edo Tzumer your problem seems to be of session time-out.You can maintain your session time out from web.config.

Similar thing can be done more easily by configuring the session state settings on your IIS where you can simply put in the session time out time or select the more appropriate session mode for your application.
