我正在使用 iTextSharp 生成 PDF。我有一个 HTMl 页面，我正在阅读 HTML 页面然后生成 PDF。但问题是页面的一半是 PDF，而页面的另一半正在用完 PDF 页面.我的意思是页面的一半以 PDF 格式显示。而页面的一半以 PDF 格式剪切。
我的代码在加载事件中是这样的..
string fileContents;
string FilePath = Server.MapPath("print-withoutlogin.html");
StreamReader mstrFileStreamReader = new StreamReader(FilePath);
try
{
fileContents = mstrFileStreamReader.ReadToEnd();
byte[] result = createPDF(fileContents.ToString()).GetBuffer();
Response.Clear();
Response.AddHeader("Content-Length", result.Length.ToString());
Response.ContentType = "application/pdf";
Response.AddHeader("Accept-Ranges", "bytes");
Response.Buffer = true;
Response.AddHeader("Expires", "0");
Response.AddHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0");
Response.AddHeader("Pragma", "public");
Response.AddHeader("content-Transfer-Encoding", "binary");
Response.AddHeader("Content-Disposition", "attachment; filename=kartik.pdf");
Response.BinaryWrite(result);
Response.Flush();
Response.End();
}
catch (Exception ex)
{
throw ex;
}
finally
{
mstrFileStreamReader.Close();
}
和
private MemoryStream createPDF(string html)
{
MemoryStream msOutput = new MemoryStream();
TextReader reader = new StringReader(html);
Document document = new Document(PageSize.A4, 0, 0, 50, 50);
PdfWriter writer = PdfWriter.GetInstance(document, msOutput);
HTMLWorker worker = new HTMLWorker(document);
//worker.SetStyleSheet(styles);
// step 4: we open document and start the worker on the document
document.Open();
worker.StartDocument();
// step 5: parse the html into the document
worker.Parse(reader);
// step 6: close the document and the worker
worker.EndDocument();
worker.Close();
document.Close();
return msOutput;
}
