Programmatically download a file as a pdf file

You need to read and process your RTF files in C#, unfortunately there is no native .NET way how to convert that content to PDF format so you need to create a PDF file in C# yourself.
For example this is one of the simplest solutions to achieve the required conversion and also export that resulting PDF file to ASP.NET's client:

var document = DocumentModel.Load("Sample.rtf");
document.Save(this.Response, "Sample.pdf");

The code uses this .NET library for Word documents processing.

Hi
This you can do by using this code:
1. Add reference for CrystalDecisions.CrystalReports.Engine.
2. Add assembly in your page like this
        <%@ Register Assembly="CrystalDecisions.Web, Version=10.5.3700.0, Culture=neutral,         PublicKeyToken=692fbea5521e1304"
            Namespace="CrystalDecisions.Web" TagPrefix="CR" %>
3.   Add CrystalReportViewer in you page deign like this
        
4. Create a Crystal Report by using a view e.g. vw_VendorList.

VB.Net Code:

        Dim Rpt As New ReportDocument
        Rpt.Load(Server.MapPath("abc.rpt"))
        Dim ds As New Data.DataSet
        Dim dt As New SqlDataAdapter("Select * from VW_VendorList", ConnString)
        dt.Fill(ds, "VW_VendorList")
        Rpt.SetDataSource(ds)
        CRV.ReportSource = Rpt                Rpt.ExportToHttpResponse(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat,         Response, True, "Vendor List Report")

After running this code, crystal report file will be exported in the form of Pdf.

Hope it will help.

It seems difficult to download the file as PDF automatically. Maybe you can try to convert RTF to PDF after downloading? 

Dear Kamal,

Thank you for your answer.

However, the documents are generated as rtf documents. What I want to do is for them to be converted to pdf when the user clicks download.

Is that possible?

How could I do it?

Thank you.

VB.Net

Dim FileName As String = Path.GetFileName(FullFileName) //Function provides file path
Response.ContentType = "application/octet-stream"
Response.AddHeader("Content-Disposition", "attachment; filename=" & FileName)
Response.WriteFile(FullFileName)
Response.[End]()

C# .NET
string FileName = Path.GetFileName(FullFileName); //Function provides file path Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", "attachment; filename=" + FileName); Response.WriteFile(FullFileName);
Response.End();

Please mark it as Accept, if it helps..
