Save SSRS Report as pdf using Reporting Services

Question

I've been trying to convert a SSRS Report to PDF and save to
my local drive using the Reporting Web Services. Though I'm able to
generate the corresponding pdf file but the contents of the file are
missing. I've checked that the report I'm trying to convert is not an
empty one. Only the header section is present there within the generated
pdf files. Below is the code I'm using:
protected void GeneratePDFFromReport(object sender, EventArgs e)
RS2005.ReportingService2005 rs;
RE2005.ReportExecutionService rsExec;
// Create a new proxy to the web service
rs = new RS2005.ReportingService2005();
rsExec = new RE2005.ReportExecutionService();
// Authenticate to the Web service using Windows credentials
rs.Credentials = new System.Net.NetworkCredential("username", "password", "domain");
rsExec.Credentials = new System.Net.NetworkCredential("username", "password", "domain");
//rsExec.Credentials = System.Net.CredentialCache.DefaultCredentials;
rs.Url = "http://servername/reportserver/reportservice2005.asmx";
rsExec.Url = "http://servername/reportserver/reportexecution2005.asmx";
string historyID = null;
string deviceInfo = null;
string format = "PDF";
Byte[] results;
string encoding = String.Empty;
string mimeType = "application/pdf";
string extension = String.Empty;
RE2005.Warning[] warnings = null;
string[] streamIDs = null;
// Path of the Report - XLS, PDF etc.
string fileName = @"C:\Report\MemberReport.pdf";
// Name of the report - Please note this is not the RDL file.
string _reportName = @"/ReportFolder/ReportName";
string _historyID = null;
bool _forRendering = false;
RS2005.ParameterValue[] _values = null;
RS2005.DataSourceCredentials[] _credentials = null;
RS2005.ReportParameter[] _parameters = null;
try
_parameters = rs.GetReportParameters(_reportName, _historyID, _forRendering, _values, _credentials);
RE2005.ExecutionInfo ei = rsExec.LoadReport(_reportName, historyID);
results = rsExec.Render(format, deviceInfo, out extension, out encoding, out mimeType, out warnings, out streamIDs);
Guid siteID = SPContext.Current.Site.ID;
GuidwebID = SPContext.Current.Site.OpenWeb().ID;
stringbudgetName = string.Empty;
try
SPSecurity.RunWithElevatedPrivileges(delegate()
using(SPSitesite = newSPSite(siteID))
using(SPWebweb = site.OpenWeb(webID))
web.AllowUnsafeUpdates = true;
web.Files.Add(web.Url + "/Shared Documents/SharepointMemberExpenseReport_" + DateTime.Now.ToShortDateString().Replace('/','-') + ".pdf", results, true);
web.AllowUnsafeUpdates = false;
catch{ }
try
FileStream stream = File.Create(fileName, results.Length);
stream.Write(results, 0, results.Length);
stream.Close();
catch { }
results = null;
catch (Exception ex)
throw ex;
Any help would highly be appreciated. Thanks.

use this code, save the byte array into format of pdf
public static byte[] ExportReportInPDF(ReportViewer ReportViewerCompetency)
Warning[] warnings;
string[] streamids;
string mimeType;
string encoding;
string filenameExtension;
byte[] bytes;
if (ReportViewerCompetency.ProcessingMode == ProcessingMode.Local)
bytes = ReportViewerCompetency.LocalReport.Render("PDF", null, out mimeType,
out encoding, out filenameExtension, out streamids, out warnings);
else
bytes = ReportViewerCompetency.ServerReport.Render("PDF", null, out mimeType,
out encoding, out filenameExtension, out streamids, out warnings);
return bytes;
