how can i read a line from a text file using "while"? In VB.net?

Answer 1

read until you hit the newline (CR and / or LF)

so it would be something like:

while not CR or not LF
read character

Answer 2

Dim YourStreamReader as StreamReader =

File.OpenText("C:\TextFile.txt")

Then call the ReadLine method from WhateverYouCallYourStreamReader, like so:

WhateverYouEtc.ReadLine( ) This returns a String, so your actual statements would look something like:

Dim SomeStringVariable as String
Dim SR as StreamReader = File.OpenText("C:\TextFile.txt")

SomeStringVariable = SR.ReadLine( )

Answer 3

Read until you will not encounter the end of file.
