推荐答案

你可以iTextSharp HTMLWorker class将HTML转换为PDF：

You can iTextSharp HTMLWorker class to convert HTML to PDF:

Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=Panel.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
var example_html = @"<p>This is <span class="" headline="" style="">some</span> sample  text<span style="">!!!</span></p>";
StringReader sr = new StringReader(example_html);
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);

pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();

Response.Write(pdfDoc);
Response.End();

一切正常但HTMLWorker已经过时了。因此，您可以使用XMLWorkerHelper获得更多优势：



首先在Nuget控制台中安装类： Install-Package itextsharp.xmlworker

然后使用iTextSharp.tool.xml添加命名空间：;

Everything will work fine but HTMLWorker is obsolete. So instead you can use XMLWorkerHelper to get more advantage:

Firstly install class in Nuget console: Install-Package itextsharp.xmlworker
Then add namespace: using iTextSharp.tool.xml;

Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=Panel.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
var example_html = @"<p>This is <span class="" headline="" style="">some</span> sample  text<span style="">!!!</span></p>";
StringReader sr = new StringReader(example_html);
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
var writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
XMLWorkerHelper.GetInstance().ParseXHtml(writer, pdfDoc, sr);
pdfDoc.Close();

Response.Write(pdfDoc);
Response.End();
