Hello everyone!

I've been trying to compare two text files line by line but I was only able to compare the file lengths. I'm creating a dance mat game and I have a text file of the steps that should be taken to get a perfect score and a text file of the actual steps taken by the user. Each text file contains a time stamp and a binary value indicating which arrow was stepped on. I'm using streamreader and streamwriter to write and read the text files.

Code:
Private Sub Score_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim GameScore As String = "C:\SavedGame.txt"
        If System.IO.File.Exists(GameScore) = True Then
            Dim objReader As New System.IO.StreamReader(GameScore)
            ValueBox.Text = objReader.ReadToEnd

            objReader.Close()

        End If

        Dim intLines As Integer = ValueBox.Lines.Length
        ScoreBox.Text = intLines 

        Dim Survive As String = "C:\I_Will_Survive.txt"
        Dim intLinesSurvive As Integer = PointsPossibleBox.Lines.Length

        PercentageBox.Text = (intLines / intLinesSurvive) * 100

        Dim f1 As New IO.StreamReader(GameScore)
        Dim f2 As New IO.StreamReader(Survive)
        CorrectSteps.Text = f2.ReadToEnd
        Dim LineNum As Integer
        Do While f1.Peek <> -1 And f2.Peek <> -1  'loop while there is stuff in the files
            LineNum += 1
            Dim f1Line As String = f1.ReadLine
            Dim f2line As String = f2.ReadLine
            If LineNum = Survive Then
                If f1Line = f2line Then
                    PercentageBox.Text = (f1Line / f2line)
                End If
            End If
        Loop
    End Sub
Please let me know if how I can modify my code to make it compare the two text files line by line! Thanks!!
