Hello,
I am creating instances of objects within my website so I can use them. Why is this throwing stackoverflow. Here is a mockup of the partical classes and classes. Error is firing in MSF_Methods class on the "private SessionVariables sv = new SessionVariables()"

website root partial class Default.aspx code behind:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using UserSession;
using MySchoolFeesMethods;
public partial class _Default : System.Web.UI.Page
{
    private SessionVariables sv = new SessionVariables();
    private MSF_Methods MSF = new MSF_Methods();
    protected void Page_Load(object sender, EventArgs e)
    {

    }
}

Open in new window




these four classes are in app_code folder
using System;
using MySchoolFeesStrings;
using MsfSisMethods;
using UserSession;

namespace MySchoolFeesMethods
{
    public class MSF_Methods
    {
        private SessionVariables sv = new SessionVariables(); // Overflow on this line
        private MSF_Strings STG = new MSF_Strings();
        private MSF_SIS SIS = new MSF_SIS();
    }
    // End Namespace Block
}

Open in new window




using System;
using System.Linq;
using UserSession;
using MySchoolFeesMethods;
using MySchoolFeesStrings;


/// <summary>
/// Summary description for MSF_SIS
/// </summary>
/// 
namespace MsfSisMethods
{
    public class MSF_SIS
    {
        private SessionVariables sv = new SessionVariables();
        private MSF_Methods MSF = new MSF_Methods();
        private MSF_Strings STG = new MSF_Strings();
    }
}

Open in new window




using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using UserSession;
using MySchoolFeesMethods;

/// <summary>
/// Summary description for MSF_Strings
/// </summary>
/// 
/// 
namespace MySchoolFeesStrings
{
    public class MSF_Strings
    {
    }
}

Open in new window




using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
using MySchoolFeesMethods;
using System.Collections;
using MySchoolFeesStrings;

namespace UserSession
{

    /// <summary>
    /// Summary description for clsSessionVariables.
    /// </summary>
    public class SessionVariables
    {
    }
}

Is this exactly how your code looks or have you just provided a skeleton?

Is there any code defined in
public class SessionVariables
{
}

This is just a skeleton but it produces the same error. I tried to attach a .zip of the website the code above but zip was rejected by experts-exchange.

You have to remove the bin and obj folders as well as any *.settings files and the project should upload fine. Alternatively, you might try using www.ee-stuff.com to upload the file. It's not hosted by EE, but it is affiliated, in a roundabout way (not officially).

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Your problem is here:

MSF_Methods
public class MSF_Methods
{
    private SessionVariables sv = new SessionVariables();
    private MSF_Strings STG = new MSF_Strings();
    private MSF_SIS SIS = new MSF_SIS();
}

Open in new window


MSF_SIS
public class MSF_SIS
{
    private SessionVariables sv = new SessionVariables();
    private MSF_Methods MSF = new MSF_Methods();
    private MSF_Strings STG = new MSF_Strings();
}

Open in new window


Each class creates an instance of the other. You need to refactor.

Sorry to be dumb. This is the first time I've experienced this. Can you give an example.

I don't have any clue as to what you're trying to achieve with your code. What is your "business" purpose here?

I have a foundational misunderstanding uf classes and namespaces. This helped me understand where the softness in my thinking is. Now I just need to do some reading and researching.

I hope I didn't run you off with my previous comment. It wasn't intended to sound off-putting. I only intended to convey that it would be difficult for me to tell you how to adjust the code without knowing what your goal is. The short answer to your question is to either remove:

private MSF_SIS SIS = new MSF_SIS();
...from MSF_Methods *or* remove:

private MSF_Methods MSF = new MSF_Methods();

...from MSF_SIS, either of which may break your design. It depends on what you are trying to accomplish  = )

Thanks. After doing some reading on organizing classes and namespaces and folders I am seeing that I have some restructuring to do. Thanks for your help! Take care.
