If you mean to replace the content of each line before : then the following code can be used

VB

Dim infos As String() = System.IO.File.ReadAllLines("TextFile.vcf")
Dim modifiedInfos As String() = infos.[Select](Function(ln) _
        If(ln.Contains(":"C), ln.Substring(ln.IndexOf(":"C) + 1), ln)).ToArray()
System.IO.File.WriteAllLines("modTextFile.vcf", modifiedInfos)

'Output for the info given in the question
'VCard
'2.1
''T GROENE HART

You have to read the file and parse its lines in order to extract meaningful (to you) info (have a look at Regex class documentation[^]).

hmm.. thanks for your answer, but I don't understand that "parse".. method.. ma by you can give me an example of it?

Can I do this in another way? ehm something like this:

I want to read the Textfile.. if this file is starting with "BEGIN:VCARD" then go to a new Line, if second line is starting with Version.. Then going tot the 3d line..

Then ehm..N = Name ( The name of the user) so The name must replace "N"
Firstname replace FN

(replace till this line)
Write the information above tot TextBox and go to new line..

END:VCARD (if last line is something like startswith "this"..then reading and writing is done, the vcard will show in textBox..

do you know how to do this?
