Sort a List of Custom Classes

[NinjaNic]

Hey everyone!

I need help sorting a list, containing a custom class. I want the list to be sorted alphabetically using the .ToString() function but it crashes on runtime. (My example code is below.)

Can somebody please teach me how to use Comparers?

Thanks a lot!

Public Class Form1
 
    Dim Websites As New List(Of URL)
 
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
 
        With Websites
            .Add(New URL("VB Forums", "www.vbforums.com", True))
            .Add(New URL("W3 Schools", "www.w3schools.com", False))
            .Add(New URL("Google", "www.google.com", True))
            .Add(New URL("Amazon", "www.amazon.com", False))
        End With
 
        ' I need to sort the list 'Websites' by alphabetical order.
        ' Using List.Sort crashes the program.
        Websites.Sort()
 
        For Each url In Websites
            ListBox1.Items.Add(url.ToString)
        Next
