Läsa in textfil med vb.net

Först så skriver vi detta längst upp av allt:
Imports System.IO

Denna rad öppnar textfilen:
Dim ioFile as new StreamReader(“TextFile.txt”)

Dessa rader loopar igenom hela filen:
Dim ioLine as string ‘ Going to hold one line at a time
Dim ioLines as string ‘ Going to hold whole file
ioLine = ioFile.ReadLine
ioLines = ioLine
While not ioLine = “”
ioLine = ioFile.ReadLine
ioLines = ioLines & vbcrlf & ioLine
End While

Detta skriver ut filen i en msgbox:
MsgBox(ioLines)
