Answer 1

The C# code below can be used in a MVC application to convert the current view to PDF and produce a PDF in a buffer that can be saved on server or sent to browser for download. The code is using evopdf library for .net to perform the HTML to PDF conversion:

[HttpPost]
public ActionResult ConvertCurrentPageToPdf(FormCollection collection)
{
    object model = null;
    ViewDataDictionary viewData = new ViewDataDictionary(model);

    // The string writer where to render the HTML code of the view
    StringWriter stringWriter = new StringWriter();

    // Render the Index view in a HTML string
    ViewEngineResult viewResult = ViewEngines.Engines.FindView(ControllerContext, "Index", null);
    ViewContext viewContext = new ViewContext(
            ControllerContext,
            viewResult.View,
            viewData,
            new TempDataDictionary(),
            stringWriter
            );
    viewResult.View.Render(viewContext, stringWriter);

    // Get the view HTML string
    string htmlToConvert = stringWriter.ToString();

    // Get the base URL
    String currentPageUrl = this.ControllerContext.HttpContext.Request.Url.AbsoluteUri;
    String baseUrl = currentPageUrl.Substring(0, currentPageUrl.Length - "Convert_Current_Page/ConvertCurrentPageToPdf".Length);

    // Create a HTML to PDF converter object with default settings
    HtmlToPdfConverter htmlToPdfConverter = new HtmlToPdfConverter();

    // Convert the HTML string to a PDF document in a memory buffer
    byte[] outPdfBuffer = htmlToPdfConverter.ConvertHtml(htmlToConvert, baseUrl);

    // Send the PDF file to browser
    FileResult fileResult = new FileContentResult(outPdfBuffer, "application/pdf");
    fileResult.FileDownloadName = "Convert_Current_Page.pdf";

    return fileResult;
}
