ArrayList from Class with Reflection

Question

I need to use Reflection for this problem. Just a simple code needed written in ASP.net and reflection. Reflection is a must.

Please take a look attached file for more info and example.

I just want to make the code below working. Output does not work as expected! Shows the same result!

Public Class JoinTables
    Public Class userz_N_user_roles
        Public userz As New userz
        Public user_roles As New user_roles   
    End Class
End Class

Public Class userz

    Public Shared id As Nullable(Of Integer) = Nothing
    Public user_name As String
    Public email_email As String
    Public user_pass As String

End Class

Public Class user_roles

    Public id As Nullable(Of Integer) = Nothing
    Public role_name As String
End Class

Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load


    Dim ArrayList_users As New ArrayList
    Dim MyUser1 As New userz
    myuser1.email_email = "1@test.com"
    myuser1.user_name = "myuser1"
    myuser1.user_pass = "mypass1"
    ArrayList_users.Add(MyUser1)



    Dim ArrayList_roles As New ArrayList
    Dim MyUserRoles1 As New user_roles
    MyUserRoles1.id = "1"
    MyUserRoles1.role_name = "Admin"
    ArrayList_roles.Add(MyUserRoles1)




    Dim myuser2 As New userz
    myuser2.email_email = "2@test.com"
    myuser2.user_name = "myuser2"
    myuser2.user_pass = "mypass2"
    ArrayList_users.Add(myuser2)


    Dim MyUserRoles2 As New user_roles
    MyUserRoles2.id = "1"
    MyUserRoles2.role_name = "Admin"
    ArrayList_roles.Add(MyUserRoles2)


    '############ REFLECTION PART ###############
    Dim MyArrayList As New ArrayList 'for Response

    Dim MyJoinTableClass As New JoinTables.userz_N_user_roles
    Dim t As Type = MyJoinTableClass.GetType

    t.InvokeMember("userz", BindingFlags.SetField, Nothing, MyJoinTableClass, New Object() {MyUser1})
    t.InvokeMember("user_roles", BindingFlags.SetField, Nothing, MyJoinTableClass, New Object() {MyUserRoles1})
    'MsgBox(MyUser1.user_name)
    MyArrayList.Add(MyJoinTableClass)

    Dim MyJoinTableClass2 As New JoinTables.userz_N_user_roles
    t = MyJoinTableClass2.GetType
    t.InvokeMember("userz", BindingFlags.SetField, Nothing, MyJoinTableClass, New Object() {myuser2})
    t.InvokeMember("user_roles", BindingFlags.SetField, Nothing, MyJoinTableClass, New Object() {MyUserRoles2})

    MyArrayList.Add(MyJoinTableClass)


    Dim filledJoinCls1 As New JoinTables.userz_N_user_roles
    filledJoinCls1 = MyArrayList(0)
    Dim filledJoinCls1_user1 As New userz
    filledJoinCls1_user1 = filledJoinCls1.userz

    MsgBox(filledJoinCls1_user1.user_name)

    Dim filledJoinCls2 As New JoinTables.userz_N_user_roles
    filledJoinCls2 = MyArrayList(1)
    Dim filledJoinCls2_user2 As New userz
    filledJoinCls2_user2 = filledJoinCls2.userz
    MsgBox(filledJoinCls1_user1.user_name & " - " & filledJoinCls2_user2.user_name)

End Sub

Output does not work as expected! Shows the same result!

If you want to create an array of specific class type, just create an array of that class type and store objects of that class into that array. — INDIA IT TECH, Apr 19 '16 at 11:02

See below,

public class Employee
{
    private long emplNbr;
    private string name;

    public long EmployeeNumber
    {
        get { return emplNbr; }
        set { emplNbr = value; }
    }

    public string EmployeeName
    {
        get { return name; }
        set { name = value; }
    }
}

Creating an Array of Objects

Employee[] StaffMembers = new Employee[2];

Initializing an Array of Objects

StaffMembers[0] = new Employee();
StaffMembers[0].EmployeeNumber = 20204;
StaffMembers[0].EmployeeName = "Harry Fields";

StaffMembers[1] = new Employee();
StaffMembers[1].EmployeeNumber = 92857;
StaffMembers[1].EmployeeName = "Jennifer Almonds";
