How to delete CR LF in a .csv file using Vb.Net

I am working on VS 2012, Vb.Net - .Net framework 4.0

This piece of code, read the .csv file and expected to rewrite the .csv file without Carriage Return.

But now, Carriage Return is created as a new line. I have also attached the screen shot.

Along with the post, i have attached the sample csv file.

 Public Sub Test()
        Try

            Dim reader As StreamReader = New System.IO.StreamReader(File.OpenRead("D:\CSV\Test.csv"))
            Dim listA As New List(Of String)()


            If File.Exists("d:\CSV\TestOut1.csv") Then
                File.Delete("d:\CSV\TestOut1.csv")
            End If

            Dim sw As New StreamWriter("d:\CSV\TestOut1.csv")
            Dim s As String = String.Empty

            While reader.Peek() >= 0
                Dim line As String = reader.ReadLine()
                Dim values As String() = line.Split(";"c)
                listA.Add(values(0))
                s = s + line + Chr(10)
            End While
            reader.Close()
            sw.WriteLine(s)
            sw.Close()
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try

    End Sub

have you tried .replace(vbcrlf, "") on the 'line' or the split array of items?
Dim values As String() = line.Split(";"c).replace(vbCrLf,"")
or
listA.Add(values(0).replace(vbCrLf,""))

search for the ascii character combination of CRLF  (13 and 10) and and don't write a new line

Or simply search for a  line with a length of less than 3 characters and ignore it

Not sure why your doing this - a .csv  file will always be created with the CRLF  at the end.
Every program that I've seen that imports a CSV file uses the CRLF as an end of file and stops writing

Change this line of code

sw.WriteLine(s)

to this

sw.Write(s)

And see if that is what you are looking for.
