Array Sort Algorithm to find duplicate values

[cmdolcet69]

i need to find a way to look through my _ReadingArrayLi st3 and see if any number stored in the inarrayindex are duplicated. I need to first collect all the data and place it into the array, once the array is filled i call my sort SortArray() Sub that will look at every arrayindex in the _ReadingArrayLi st3, at this time after that i can;t seem to find out how to compare values in the array. Below is the code i have been working on.

Thanks

Public Sub SortArraylist()
 
        For Each intarrayindex In _ReadingArrayList3
            If _ReadingArrayList3.Then Then
 
            Else
            End If
        Next
    End Sub

As someone said up the line, use a collection. As in:

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim myAry() As Integer = {3, 6, 4, 7, 5, 5, 3, 8, 9, 1, 3}
        Dim myCollection As New Collection
        For x As Integer = 0 To UBound(myAry)
            Try
                myCollection.Add(myAry(x), myAry(x))
            Catch
            End Try
        Next
        ReDim myAry(myCollection.Count)
        For x As Integer = 1 To myCollection.Count
            myAry(x) = myCollection.Item(x)
        Next
    End Sub
