wkhtmltopdf - convert html code to pdf directly in C#

Question

I know this tool looks up on a url and converts the repsponse to pdf. How do I convert a

 content..  

into a pdf?

Answer 1

I found a way. You can set up another to output the normal html. And use that url as the input value of wkhtml2pdf process.

----------Edit

public byte[] WKHtmlToPdf(string url_input)
    {
        try
        {
            var fileName = " - ";
            var wkhtmlDir = ConfigurationSettings.AppSettings["wkhtmlDir"];
            var wkhtml = ConfigurationSettings.AppSettings["wkhtml"];
            var p = new Process();

            string url = Request.Url.GetLeftPart(UriPartial.Authority) + @"/application/" + url_input;

            p.StartInfo.CreateNoWindow = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.RedirectStandardError = true;
            p.StartInfo.RedirectStandardInput = true;
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.FileName = wkhtml;
            p.StartInfo.WorkingDirectory = wkhtmlDir;

            string switches = "";
            switches += "--print-media-type ";
            switches += "--margin-top 10mm --margin-bottom 10mm --margin-right 10mm --margin-left 10mm ";
            switches += "--page-size Letter ";
            p.StartInfo.Arguments = switches + " " + url + " " + fileName;
            p.Start();

            //read output
            byte[] buffer = new byte[32768];
            byte[] file;
            using (var ms = new MemoryStream())
            {
                while (true)
                {
                    int read = p.StandardOutput.BaseStream.Read(buffer, 0, buffer.Length);

                    if (read <= 0)
                    {
                        break;
                    }
                    ms.Write(buffer, 0, read);
                }
                file = ms.ToArray();
            }

            // wait or exit
            p.WaitForExit(60000);

            // read the exit code, close process
            int returnCode = p.ExitCode;
            p.Close();

            return returnCode == 0 ? file : null;
        }
        catch (Exception ex)
        {

           // set your exceptions here
            return null;
        }
    }

----------web.config key example

The basic idea is passing url to the exe as an argument.

HTH !
