VB.net write to text file WITHOUT CrLf

I have to send a file to our EDI van, the record length is set to 80 characters, and there CANNOT be a CrLf after each line.

I am using VB.net (2008), using StreamWriter.  

Sample code:
        Dim addInfo2 As New System.IO.StreamWriter((yFileNameOut), True)
        Do While indEof = False
            If (yPosition_int + yLength_int) <= yStringLength_int Then
                yStringOut = yStringBuild.Substring(yPosition_int, yLength_int)
                yPosition_int = yPosition_int + 80 + yIndex_int
                yIndex_int = 0
                indEof = True
                If yPosition_int < yStringLength_int Then
                    yLength_int = yStringLength_int - yPosition_int
                    yStringOut = yStringBuild.Substring(yPosition_int, yLength_int)
                End If
            End If

            If yPosition_int > yStringLength_int Then
                indEof = True
            End If

By using WriteLine I get CrLf after each line to text file.  If I use Write instead, text file contains one long character string.

So question is how to write to text file (using VB.net), writing numerous lines, without CrLf at end of each line.

What would you want to use instead of vbCrlf? A whitespace? In that case replace vbCrlf with a whitespace

I say use Write instead of WriteLine (because WriteLine automatically adds vbCrlf, and attach " " at the end of each written line:

addInfo2.Write(yStringOut & " ")

>>writing numerous lines, without CrLf at end of each line.
Major problem there - the crlf denotes and end of line/start new line.

Just what is wrong with using write instead?  The app using this file (implied in your question) expects 80 char long records and barfs with the extra 2 chars you put in by using WriteLine.
