VB .Net text output help needed

Visual Basic 2005 Express Edition, Windows 2000 Pro.

I'm having some problems with a file output, I need to generate a file of HTML from a loop, with non-loop HTML before and after.
I'm using this code to create the file with looped HTMl and after, but the problem comes with getting some before the loop output.

~~~~~~~~~~~~~~~~~~~~

        Dim strOutputFilePath As String
        Dim strImagePath As String
        Dim intPosition As Integer
        Dim intEnd As Integer

        strOutputFilePath = "C:\Output.html"
        strImagePath = "C:\img\"
        intEnd = lstQuestionList.Items.Count - 1
        intPosition = 0

        Dim OutputArray(intEnd) As String

        While intPosition <= intEnd
            OutputArray(intPosition) = "<p><img src=""" + strImagePath + lstList.Items.Item(intPosition) + ".jpg""></p>"
            intPosition = intPosition + 1
        End While

        System.IO.File.WriteAllLines(strOutputFilePath, OutputArray)
        System.IO.File.AppendAllText(strOutputFilePath, "End of page")

~~~~~~~~~~~~~~~~~


The WriteAllLines function needed to output the array causes anything in the file to be overwritten, and so I can't add any text before this.

Any ideas, experts?

Thanks :D

Oh, and incase you need clarification of the output that code gives, here's an example.

<p><img src="C:\img\1.jpg"></p>
<p><img src="C:\img\2.jpg"></p>
<p><img src="C:\img\3.jpg"></p>
<p><img src="C:\img\4.jpg"></p>
<p><img src="C:\img\5.jpg"></p>
<p><img src="C:\img\6.jpg"></p>
End of page

Perhaps a StreamWriter will work for you:

        Dim sw As New System.IO.StreamWriter(strOutputFilePath)

        While intPosition <= intEnd
            sw.WriteLine("<p><img src=""" + strImagePath + lstList.Items.Item(intPosition) + ".jpg""></p>")

            intPosition = intPosition + 1
            sw.WriteLine()
        End While

        sw.Close()
        sw.Dispose()

            'sw.WriteLine()    <My mistake, remove this line.
        End While

        sw.Close()
        sw.Dispose()

Another approach could be to use a string builder:

        Dim strOutputFilePath As String
        Dim strImagePath As String
        Dim intPosition As Integer
        Dim intEnd As Integer

        Dim sb As New System.Text.StringBuilder()

        strOutputFilePath = "C:\Output.html"
        strImagePath = "C:\img\"
        intEnd = lstQuestionList.Items.Count - 1
        intPosition = 0

        Dim OutputArray(intEnd) As String

        sb.Append("<html><head></head><body>")

        While intPosition <= intEnd
            sb.Append("<p><img src=""" + strImagePath + lstList.Items.Item(intPosition) + ".jpg""></p>" & vbCrLf)

            intPosition = intPosition + 1
        End While

        sb.Append("</body></html>")

        System.IO.File.WriteAllLines(strOutputFilePath, sb.ToString().Split(vbCrLf))
        System.IO.File.AppendAllText(strOutputFilePath, "End of page")

Thanks, VBRocks - The StringBuilder solution worked best, though it formats better for notepad to use Chr(13)'s instead of vbCrLf.

Points awarded, Cheers.
