#002 Render ReportViewer as PDF

If you want to programatically save a Microsoft.Reporting.WinForms.ReportViewer as a PDF to the filesystem or a database, the Render(...) Method will help you out by returning a byte array of the rendered file content.

Here is the code snippet:

   1:  byte[] fileData = null;

   2:  Warning[] warnings;

   3:  string[] streamids;

   4:  string mimeType;

   5:  string encoding;

   6:  string extension;

   7:   

   8:  fileData = reportViewer.LocalReport.Render(

   9:   "PDF", null, out mimeType, out encoding,

  10:    out extension,

  11:   out streamids, out warnings);
