Hi All,
after much R&D also, I couldnot find solution to this. Can anybody help on the below issue addressed please? I'm facing performance issue while downloading PDF report using C#

C#

public class nachkPDF:System.Web.UI.Page
{
    private void Page_Load(object sender, System.EventArgs e)
    {
        ZurichNS.Ctl.Nachcalculation model = new ZurichNS.Ctl.Nachcalculation();
        String year = Request.Params["year"];
        long vstGC = -1;
        long mnr = -1;
        try
        {
            vstGC = long.Parse(Request["groupid"]);
        }
        catch
        {
            vstGC = -1;
        }
        try
        {
            mnr = long.Parse(Request["id"]);
        }
        catch
        {
            mnr = -1;
        }
        string path = model.createPDF(year, vstGC, mnr, Request, Session);
        Response.ClearHeaders();
        Response.ContentType="application/pdf";
        Response.AppendHeader("Connection","keep-alive");
        Response.AppendHeader("Content-Disposition"," attachment; filename = " + Session["user_id"] + "_" + year + "_nachk.pdf");
        long lngFileSize;
        byte[] bytBuffer;
        int iReading;
        string sFileName = path;
        System.IO.Stream outStream = Response.OutputStream;
        System.IO.FileStream fStream = new  System.IO.FileStream(sFileName,System.IO.FileMode.OpenOrCreate,System.IO.FileAccess.Read);
        lngFileSize = fStream.Length;
        bytBuffer = new byte[(int)lngFileSize];
        while((iReading=fStream.Read(bytBuffer,0,(int)lngFileSize)) > 0)
        {
            outStream.Write(bytBuffer,0,iReading);
        }
        fStream.Close();
        outStream.Close();
        Response.WriteFile(path);
        Response.End();
    }
    #region Web Form Designer generated code
    override protected void OnInit(EventArgs e)
    {
        //
        // CODEGEN: This call is required by the ASP.NET Web Form Designer.
        //
        InitializeComponent();
        base.OnInit(e);
    }

model.PDF internally calling 3 methods(mergeMaklersData,getAllMaklerdataNach,getOldYearMaklerdata)

ArrayList calcs = mData.mergeMaklersData((ArrayList)mData.getAllMaklerDataNach(y, oldYear.ToString(), vstGC, mnr),
(ArrayList)mData.getOldYearMaklerData(y, vstGC, mnr));

Use your debugger and try to isolate the exact call that takes that much time...

Kornfeld Eliyahu Peter 20-May-15 6:04am

Your code has several parts, like loading file, handling response and creating the PDF...
Isolate the exact part (probably to a single method call) that uses the most time of that 20 minutes...

There are some foreach loops in mergeMaklerData which are taking more time.

Kornfeld Eliyahu Peter 20-May-15 6:36am

Go into mergeMaklerData and try to isolate the exact lines that use the time up...

you mean do i need to optimize the front end or stored procedures????

Try this code:

protected void GetCTReport(string FSID)
    {
        try
        {
            ReportDocument rd = new ReportDocument();
            rd.Load(Page.Server.MapPath("CementingTreatmentReport.rpt"));
            rd.SetParameterValue("@FID", FSID);
            rd.SetDatabaseLogon("DB_9B08BD_automobile_admin", "webclient786");
            Print2Pdf(rd);

        }
        catch (Exception ex)
        {
            Response.Write(ex.Message);
        }

    }

protected void Print2Pdf(ReportDocument rd)
    {
        try
        {

            ReportDocument cryRpt = new ReportDocument();

            cryRpt = rd;

            ExportOptions CrExportOptions;

            DiskFileDestinationOptions CrDiskFileDestinationOptions = new DiskFileDestinationOptions();

            PdfRtfWordFormatOptions CrFormatTypeOptions = new PdfRtfWordFormatOptions();

            string strDate = DateTime.Now.ToShortDateString();

            string Path = "~/ExportedReports/OptReport_NPS.pdf";

            if (Path != null || Path != string.Empty)
            {
                if (System.IO.File.Exists(Path))
                {
                    System.IO.File.Delete(Path);
                }
            }

            CrDiskFileDestinationOptions.DiskFileName = Server.MapPath(Path);

            CrExportOptions = cryRpt.ExportOptions;

            {

                CrExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;

                CrExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;

                CrExportOptions.DestinationOptions = CrDiskFileDestinationOptions;

                CrExportOptions.FormatOptions = CrFormatTypeOptions;

            }

            cryRpt.Export();
            Response.Redirect("SaveFile.ashx", false);//redirecting to GenericHandler
        }
        catch (Exception ex)
        {
            //throw;
            lblmsg.Visible = true;
            lblmsg.Text = ex.Message.ToString();
        }
    }

Create one Generic Handler:

public void ProcessRequest (HttpContext context)
{

        string Path = HttpContext.Current.Server.MapPath("~/ExportedReports/OptReport_NPS.pdf");
        byte[] bytesPDF = System.IO.File.ReadAllBytes(Path);

        if (bytesPDF != null)
        {
            System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;
            response.ClearContent();
            response.Clear();
            string strDate = DateTime.Now.ToShortDateString();
            response.AddHeader("content-disposition", "attachment;filename= OptReport_" + strDate + ".pdf");
            response.ContentType = "application/octectstream";
            response.BinaryWrite(bytesPDF);
            response.End();
        }
}

Hope it would help you.
