Try this approach using the hiqpdf html to pdf converter, a commercial product:
public class HomeController : Controller
{
public ActionResult Index()
{
ViewBag.Message = "Welcome to ASP.NET MVC!";
Session["MySessionVariable"] = "My Session Variable Value assigned in Index";
return View();
}
public ActionResult About()
{
return View();
}
public string RenderViewAsString(string viewName, object model)
{
// create a string writer to receive the HTML code
StringWriter stringWriter = new StringWriter();
// get the view to render
ViewEngineResult viewResult = ViewEngines.Engines.FindView(ControllerContext, viewName, null);
// create a context to render a view based on a model
ViewContext viewContext = new ViewContext(
ControllerContext,
viewResult.View,
new ViewDataDictionary(model),
new TempDataDictionary(),
stringWriter
);
// render the view to a HTML code
viewResult.View.Render(viewContext, stringWriter);
// return the HTML code
return stringWriter.ToString();
}
[HttpPost]
public ActionResult ConvertThisPageToPdf()
{
// get the HTML code of this view
string htmlToConvert = RenderViewAsString("Index", null);
// the base URL to resolve relative images and css
String thisPageUrl = this.ControllerContext.HttpContext.Request.Url.AbsoluteUri;
String baseUrl = thisPageUrl.Substring(0, thisPageUrl.Length - "Home/ConvertThisPageToPdf".Length);
// instantiate the HiQPdf HTML to PDF converter
HtmlToPdf htmlToPdfConverter = new HtmlToPdf();
// hide the button in the created PDF
htmlToPdfConverter.HiddenHtmlElements = new string[] { "#convertThisPageButtonDiv" };
// render the HTML code as PDF in memory
byte[] pdfBuffer = htmlToPdfConverter.ConvertHtmlToMemory(htmlToConvert, baseUrl);
// send the PDF file to browser
FileResult fileResult = new FileContentResult(pdfBuffer, "application/pdf");
fileResult.FileDownloadName = "ThisMvcViewToPdf.pdf";
return fileResult;
}
[HttpPost]
public ActionResult ConvertAboutPageToPdf()
{
// get the About view HTML code
string htmlToConvert = RenderViewAsString("About", null);
// the base URL to resolve relative images and css
String thisPageUrl = this.ControllerContext.HttpContext.Request.Url.AbsoluteUri;
String baseUrl = thisPageUrl.Substring(0, thisPageUrl.Length - "Home/ConvertAboutPageToPdf".Length);
// instantiate the HiQPdf HTML to PDF converter
HtmlToPdf htmlToPdfConverter = new HtmlToPdf();
// render the HTML code as PDF in memory
byte[] pdfBuffer = htmlToPdfConverter.ConvertHtmlToMemory(htmlToConvert, baseUrl);
// send the PDF file to browser
FileResult fileResult = new FileContentResult(pdfBuffer, "application/pdf");
fileResult.FileDownloadName = "AboutMvcViewToPdf.pdf";
return fileResult;
}
}

只需创建 pdf 服务器端并返回 File 而不是 html 视图。我不知道您使用哪种 pdf 提供程序,但这是 iTextSharp 的解决方案:
