About converting Html content to PDF format

Guest User

Hello Everyone,

Hope everyone is fine.

I have HTML content and want to convert that to pdf format and save it to a local project folder.

I have installed HtmlRender.PdfSharp NuGet library in my project.

I have also tried a few examples but did not work out. Even I did not find any error in that code.

So I am not getting, what I am doing wrong.

I have tried the following code :

protected void buttonClick(Object sender, EventArgs e)
{
Byte[] fileContent=PdfSharpConvert("My HTML Layout");
string fileName = "New.pdf";
string[] stringParts = fileName.Split(new char[] { '.' });
string strType = stringParts[1];
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.AddHeader("content-disposition", "attachment; filename=" + fileName);
//Set the content type as file extension type
Response.ContentType = strType;
//Write the file content
this.Response.BinaryWrite(fileContent);
this.Response.End();
}
public static Byte[] PdfSharpConvert(String html)
{
Byte[] res = null;
using (MemoryStream ms = new MemoryStream())
{
var pdf = TheArtOfDev.HtmlRenderer.PdfSharp.PdfGenerator.GeneratePdf(html, PdfSharp.PageSize.A4);
pdf.Save(ms);
res = ms.ToArray();
}
return res;
}

Please let me know anything can be done to fix these.

Thank you in advance.

You can try using the DocumentConverter from the LEADTOOLS SDK to take the HTML data comprised within a HTML file and convert it to a searchable PDF. You can build on this code in a MVC application:
using (DocumentConverter documentConverter = new DocumentConverter())
{
   var inFile = @"C:\Input\Leadtools.html");
   var outFile = @"C:\Output\output.pdf");
   var jobData = DocumentConverterJobs.CreateJobData(inFile, outFile, DocumentFormat.Pdf);
   jobData.JobName = "conversion job";

   var documentWriter = new DocumentWriter();
   documentConverter.SetDocumentWriterInstance(documentWriter);

   var renderingEngine = new AnnWinFormsRenderingEngine();
   documentConverter.SetAnnRenderingEngineInstance(renderingEngine);

   var job = documentConverter.Jobs.CreateJob(jobData);
   documentConverter.Jobs.RunJob(job);
}

Thank you everyone for your quick responses.

I want to convert that HTML format to pdf and then download or email that pdf to user.
I am requesting that code in MVC technology.
I have tried almost every reply from this thread, but not sure where I am doing a mistake.
The file is not getting downloaded.
So if someone has a Sample project code or Controller-View, Please reply me.

Thank you!
