VB 2008 - Reading a text file and printing each line (console)?

Question

I am making a console application that needs to be able to print the contents of a text file, one line at a time.
My attempt at this has failed - it prints a single, empty line.
I cannot find anywhere online where I can learn how to do this, so does anybody know?

Answer 1

This is what I did in one of my projects, it's using .NET 4 but should be able to use it with a few minor tweaks.



Private Sub ReadLines(ByVal fileName As String)

Dim str() As String = File.ReadAllLines(fileName)



Using sw As New IO.StreamWriter(fileName)

For Each Line As String In str

sw.WriteLine(Line)

Next

End Using

End Sub

Answer 2

you should apply string manipulation. truthfully, you search for each and each letter in the line for the "|" separator and any be conscious that comes earlier that separator is archives. something like this: dim i as integer, j as integer do even as( i < str.length() and mid(str, i, a million) <> "|" ) i +=a million 'i = i + a million loop textbox1.textual content = mid(str, a million, i) then proceed on... j = i do even as( j < str.length() and mid(str, j, a million) <> "|" ) j += a million loop textbox2.textual content = mid(str, i, j) probable no longer the precise thanks to do it, notwithstanding it quite is the truthfully element i ought to imagine of.

Answer 3

Ignoring the "one line at a time" part of your request, and assuming we're in C# (not that any of the other .NET languages are much different) you could write:



string whole = File.ReadAllText("MyFile.txt");

Console.Write(whole);



Taking into account you're "one line at a time" because you probably did mean it:



string[] lines = File.ReadAllLines("MyFile.txt");

foreach (string line in lines)

{

Console.WriteLine(line);

}
