How are saving sImputLine? As I see you are overwritting it with each read.
I use:

Help with Code Tags

(Toggle Plain Text)

    Dim ary As String()

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If My.Computer.FileSystem.FileExists("c:\test.txt") Then
            Dim str As String = My.Computer.FileSystem.ReadAllText("c:\test.txt")
            str.Split(ary, vbNewLine)
        End If
    End Sub

Now all your data is in an array.
