[RESOLVED] Read/compare particular line from textfile

Hi,

I have a 2 textfiles with a few lines of text.

e.g. textfile1

pos1:1
pos2:10
pos3:1
pos4:0

e.g. textfile2

pos1:1
pos2:9
pos3:1
pos4:0

I need to open both files and compare the lines without knowing which line is different. (mgsbox (pos2.value)<< something like this)

Anyone?

Just open the first one, put in array, open the second and go through each line and compare each line with the same position in the array...

Sample..

VB.NET Code:

Dim arrFirst() As String = IO.File.ReadAllLines("PATH")
        Dim reader As New IO.StreamReader("PATH")
        Dim i As Integer = 0
 
        While True
            Dim line As String = reader.ReadLine
            If line Is Nothing Then Exit Sub
            If arrFirst(i) <> line Then
                MsgBox("Not equal")
                Exit While
            End If
            MsgBox("Equal")
            i += 1
        End While

Thanks mickey, but it seems that I have to correct my question. I do need to know which line is different. Sorry for the misunderstanding.

Instead of the MsgBox that says not equal you can save the line value to a string, or if are several different lines you can add them to an arraylist...

[EDIT] - The number of the line or the value?

If it's the number it will be the value of i+1.
If it's the line string it will be the line string
