The Syncfusion HTML to PDF converter is a .NET library for converting webpages, SVG, MHTML, and HTML to PDF using C#. It is reliable and accurate. The result preserves all graphics, images, texts, fonts, and the layout of the original HTML document or webpage. Using this library, you can convert the MVC view to PDF in C# and VB.NET.
Steps to convert the MVC view to PDF programmatically:
- Create a new ASP.NET MVC application project.
- Install the Syncfusion.HtmlToPdfConverter.QtWebKit.AspNet.Mvc5 NuGet package as a reference to your MVC application from NuGet.org.
- Copy the QtBinaries folder from the HtmlToPdfConverter NuGet package installed location to Bin folder of the project. You can place the QtBinaries other than bin folder, then it is mandatory to set the QtBinaries folder path to the WebKitPath in WebKitConverterSettings explicitly.
- Add new button in Index.cshtml for converting HTML to PDF.
@{ Html.BeginForm("ConvertToPDF", "Home", FormMethod.Post);
{
<h2><input type="submit" value="Convert To PDF"></h2>
}
}
- Include the following namespaces in HomeController.cs file.
// [C# code]
using Syncfusion.HtmlConverter;
using Syncfusion.Pdf;
using System.IO;
using System.Text;
using System.Text.RegularExpressions;
- Include the following code snippet in the HomeController.cs to convert the MVC view to PDF.
public ActionResult ConvertToPDF()
{
//Getting Index view page as HTML
ViewEngineResult viewResult = ViewEngines.Engines.FindView(ControllerContext, "Index", "");
string html = GetHtmlFromView(ControllerContext, viewResult, "Index", "");
string baseUrl = string.Empty;
//Convert the HTML string to PDF using WebKit
HtmlToPdfConverter htmlConverter = new HtmlToPdfConverter(HtmlRenderingEngine.WebKit);
WebKitConverterSettings settings = new WebKitConverterSettings();
//Assign WebKit settings to HTML converter
htmlConverter.ConverterSettings = settings;
//Convert HTML string to PDF
PdfDocument document = htmlConverter.Convert(html, baseUrl);
MemoryStream stream = new MemoryStream();
//Save and close the PDF document
document.Save(stream);
document.Close(true);
return File(stream.ToArray(), "application/pdf", "ViewAsPdf.pdf");
}
private string GetHtmlFromView(ControllerContext context, ViewEngineResult viewResult, string viewName, object model)
{
context.Controller.ViewData.Model = model;
using (StringWriter sw = new StringWriter())
{
//View not found, throw an exception with searched locations
if (viewResult.View == null)
{
var locations = new StringBuilder();
locations.AppendLine();
foreach (string location in viewResult.SearchedLocations)
{
locations.AppendLine(location);
}
throw new InvalidOperationException(string.Format("The view '{0}' or its master was not found, searched locations: {1}", viewName, locations));
}
ViewContext viewContext = new ViewContext(context, viewResult.View, context.Controller.ViewData, context.Controller.TempData, sw);
viewResult.View.Render(viewContext, sw);
string html = sw.GetStringBuilder().ToString();
//Add the BaseURL for the resources used in the MVC view
string baseUrl = string.Format("{0}://{1}", HttpContext.Request.Url.Scheme, HttpContext.Request.Url.Authority);
html = Regex.Replace(html, "<head>", string.Format("<head><base href=\"{0}\" />", baseUrl), RegexOptions.IgnoreCase);
return html;
}
}
