Removing duplicates from an arraylist

[shaunieb]

I'm pulling my hair out here , i know im dong something really small wrong.

What is the recommended way to remove duplicate items in a arraylist? Im so tired, ive spent hours trying to figure this out

Please any help would be greatly appreciated.

Here's a class you can use:

Public Class myArrayList
    Inherits ArrayList
    Sub EliminateDuplicates()
        Dim i As Integer = 0
        Dim delEntries As ArrayList
        While i <= MyBase.Count - 2
            Dim j As Integer = i + 1
            While j <= MyBase.Count - 1
                If MyBase.Item(i).ToString = MyBase.Item(j).ToString Then
                    MyBase.RemoveAt(j)
                End If
                j = j + 1
            End While
            i = i + 1
        End While
    End Sub

Maybe this world is another planet’s Hell.
