online waiting~~ about Session Questions

楼主flycatcq（飞天猫）2004-05-02 17:19:40 在 .NET技术 / ASP.NET 提问

like this:
one .aspx
Session["Number_YN"] = intRandom; //input Session

other .aspx
string RintNum = Session["Number_YN"].ToString();
if(tbCodeNumber_Login.Text != RintNum)
{
lblUserLoginErr.Text = "password Err。";
return;
}
else
{
lblUserLoginErr.Text = "Done";
}

Questions:

1、Can not Load Session So Can not to compare

2、It's Session configuration problem I think.But my configuration it's all right.Web.config like this:
<sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes" cookieless="true" timeout="20" />
Global.asax like this:
protected void Session_Start(Object sender, EventArgs e)
{
Session["Number_YN"] = "";
}

3、forgive me used English representation the problem.because nohave chinese input.

thanks! 问题点数：50、回复次数：17Top

现在没有环境，不知道那有问题，不过正常Session应该可以使用，你是否添加了命名空间
using System.Web.SessionState;

要是还不行，可以试试Cache("")Top
