Suggest correction in code to render report

I was suggested the following code to programmatically render SSRS report in PDF format. I tried it but it is not working.

Can any body suggest what might be required? Thanks

Dim format As String = "PDF"
    Dim fileName As String = "C:\Output.pdf"
     Dim reportPath As String = "/[Report Folder]/Invoice"

    ' Prepare Render arguments
    Dim historyID As String = Nothing
    Dim deviceInfo As String = Nothing
    Dim extension As String = Nothing
    Dim encoding As String
    Dim mimeType As String = "application/pdf"
    Dim warnings() As Microsoft.Reporting.WinForms.Warning = Nothing
    Dim streamIDs() As String = Nothing
    Dim results() As Byte

    ReportViewer1.LocalReport.Render(format, deviceInfo, mimeType, encoding, fileName, streamIDs, warnings)


    ' Open a file stream and write out the report
    Dim stream As FileStream = File.OpenWrite(fileName)
    stream.Write(results, 0, results.Length)
    stream.Close()

It doesn't work because you never assign anything to the results variable so the FileStream will never get anything written to it. You need to assign the result of the Render method to results:

results = ReportViewer1.LocalReport.Render(format, deviceInfo, mimeType, encoding, fileName, streamIDs, warnings)
