How on Earth this can be related to WPF?

And what did you try? What you show is pretty unrelated to the problem, as well as WPF. You are not even trying to analyze the result it ReadAllText...

Solution 1

Without your if operator, assign the result of ReadAllText to some string variable and parse it to get what you need. Start with System.String.Split:

Here is the code that i used..

VB

Dim fileAs String = Application.StartupPath & "\file.txt"

      If System.IO.File.Exists(file.txt) = True Then
          Dim objReader As New System.IO.StreamReader(file.txt)
          file= objReader.ReadToEnd

         ' Or you can use objReader.ReadLine '
      Else
          MsgBox("File does not exists")
          Exit Sub
      End If
