Go4Expert - Arraylist searching troubles

I’m having some trouble with my array list. I’m using my array list to store numbers in it. Adding stuff to it works fine. But searching the array list to see if it already contains a number is proving more difficult. Here’s what I’ve got:

Code:

Public Sub TestNum()

        Dim p As String

        Dim q As String = frm_EnterInfo.TextBox1.Text

        For Each p In c_TestArrayClass.NumArray



            If p = q Then



                frm_enterInfo.Label3.Text = "Found in Array"

                Exit For

            Else



                frm_enterInfo.Label3.Text = "Not Found"



            End If

        Next

   

    End Sub

I get this error when I run it "Conversion from type 'EnterInfoClass' to type 'String' is not valid" and it points to this part:

Code:

For Each p In c_TestArrayClass.NumArray

Could anyone help me?
