Asp.Net MVC如何获取视图生成PDF [英] Asp.Net MVC how to get view to generate PDF

问题描述

我想调用一个控制器上的操作。有控制器从模型中获取数据。该视图然后运行，并生成一个PDF文件。我发现的唯一的例子是娄<一的一篇文章中href=\"http://whereslou.com/2009/04/12/returning-pdfs-from-an-aspnet-mvc-action\">http://whereslou.com/2009/04/12/returning-pdfs-from-an-aspnet-mvc-action.他的code是非常优雅。该视图使用iTextSharp的生成PDF。唯一不足的是他的榜样使用星火视图引擎。有没有办法做的标准的微软视图引擎类似的事情？

I would like to call an action on a controller. Have the controller get the data from the model. The view then runs and generates a PDF. The only example I have found is in an article by Lou http://whereslou.com/2009/04/12/returning-pdfs-from-an-aspnet-mvc-action. His code is very elegant. The view is using ITextSharp to generate the PDF. The only downside is his example uses the Spark View Engine. Is there a way to do a similar thing with the standard Microsoft view engine?

推荐答案

我用iTextSharp的生成在MVC动态PDF文件。所有你需要做的就是把你的PDF到一个流对象，然后你的ActionResult返回FileStreamResult。我还设置了内容部署，以便用户可以下载它。

I use iTextSharp to generate dynamic PDF's in MVC. All you need to do is put your PDF into a Stream object and then your ActionResult return a FileStreamResult. I also set the content-disposition so the user can download it.

public FileStreamResult PDFGenerator()
{
    Stream fileStream = GeneratePDF();

    HttpContext.Response.AddHeader("content-disposition", 
    "attachment; filename=form.pdf");

    return new FileStreamResult(fileStream, "application/pdf");
}

我也有code，让我带一个模板PDF，写文本和图像等它（如果你想这样做）。

I also have code that enables me to take a template PDF, write text and images to it etc (if you wanted to do that).

• 注：必须将流位置设置为0

private Stream GeneratePDF()
{
    //create your pdf and put it into the stream... pdf variable below
    //comes from a class I use to write content to PDF files

    MemoryStream ms = new MemoryStream();

    byte[] byteInfo = pdf.Output();
    ms.Write(byteInfo, 0, byteInfo.Length);
    ms.Position = 0;

    return ms;
}
