Problem with Class name

[tshad]

I am getting the following messages from my compile code:

PageInit.cs(43,71): error CS0246: The type or namespace name 'User' could
not be
found (are you missing a using directive or an assembly reference?)
PageInit.cs(43,76): error CS0117: 'object' does not contain a definition for
'LastPageVisited'

User is an object I have in my session variables that works fine in VB.Net
but there is something missing here.

The Compiler Code is:

C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\csc /t:library PageInit.cs
/r:system.web.dll /r:system.data.dll /r:system.dll
/r:Microsoft.VisualBasic.dll /r:refresh.dll /r:User.dll

The code snippet giving me the problem looks like (the last line is the
offender):
************************************
using System;
using System.Web;
using System.IO;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.SessionState;
using System.Data;
using System.Data.SqlClient;
using System.Collections;
using Microsoft.VisualBasic;
using MyFunctions;

namespace MyFunctions
{
public class PageInit
{
public static void PageSetup(MyFunctions.Page thePage)
{
HttpContext.Current.Session["LastPageVisited"] =
(User)HttpContext.Current.Session["User"].LastPageVisited;
***********************************

My User class looks something like:
********************************
using System;
using System.IO;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
using System.Collections;
using MyFunctions;
using FtsData;

namespace RolesBasedAuthentication
{
[Serializable]
public class User
{
private string lastPageVisited = "";
....
public string LastPageVisited
{
get { return lastPageVisited; }
set { lastPageVisited = value; }
}
....
*************************************

This is the piece that is giving me the problem:

(User)HttpContext.Current.Session["User"].LastPageVisited

Why doesn't it see the User object? It is in the MyFunctions namespace. I
also tried adding the following line just to see:

using Myfunctions;

But that didn't work, either.

Thanks,

Sorry, this is resend of my previous message.

I got an error that said the old one didn't get sent and it obviously did.

Tshad,

The chance that User is abigious in one of the other namespaces that you
have declared as using is high. Did you try it with writting the full path
to that. (Because of this it is not so clever to call a class User by the
way, however, it is not so bad as trying to name a class "string").

The problem here was that I didn't have a "using RolesBasedAuthentication;"
line. I thought it was in the "MyFunction" namespace.

I am still getting this error, even if I change:

HttpContext.Current.Session["LastPageVisited"] =
(User)HttpContext.Current.Session["User"].LastPageVisited;

to

HttpContext.Current.Session["LastPageVisited"] =
(User)(HttpContext.Current.Session["User"]).LastPageVisited;

or

HttpContext.Current.Session["LastPageVisited"] =
(RolesBasedAuthentication.User)(HttpContext.Current.Session["User"]).LastPageVisited;

But the Class User does have a LastPageVisited:

public string LastPageVisited
{
get { return lastPageVisited; }
set { lastPageVisited = value; }
}

Am I casting it wrong??

Thanks,

Tom

I tried that but that wasn't the problem.

Part of it was that I thought the namespace was "MyFunctions" but it wasn't.
It was RolesBasedAuthentication. When I added:

using RolesBasedAuthentication;

That fixed the first problem.

HttpContext.Current.Session["LastPageVisited"] =
(User)(HttpContext.Current.Session["User"]).LastPageVisited;

That's trying to cast the result of LastPageVisited to User. Change it
to:

HttpContext.Current.Session["LastPageVisited"] =
((User)HttpContext.Current.Session["User"]).LastPageVisited;

HttpContext.Current.Session["LastPageVisited"] =
(User)(HttpContext.Current.Session["User"]).LastPageVisited;

That's trying to cast the result of LastPageVisited to User. Change it
to:

HttpContext.Current.Session["LastPageVisited"] =
((User)HttpContext.Current.Session["User"]).LastPageVisited;

That was it.

Took me a little while to see why. I was thinking that I was looking only
at HttpContext.Current.Session["User"]) by doing it my way, but I can see
now why that is not the case.

Thanks,

Tom
