HttpContext.Current.Response.AddHeader("Content-Length", bb.Length.ToString());
HttpContext.Current.Response.ContentType = "application/pdf";
HttpContext.Current.Response.BinaryWrite(bb);
bb是一个字节数组. 对于发送文件
bb is a bytes array. And this is working fine regarding the "sending the file
对用户"部分.
我面临的问题是字节的创建

推荐答案
看看这是否有助于创建字节数组，我正在使用html解析器将我的xml文档转换为pdf-
See if this helps in creating the byte array, i am using html parser to convert my xml document to pdf -
// Using iTextSharp to construct a PDF document
// Create a document-object
Document document = new Document(PageSize.A4);
// Create a writer that listens to the document
// and directs a XML-stream to a MemoryStream
using (MemoryStream ms = new MemoryStream())
{
PdfWriter.GetInstance(document, ms);
document.Open();
System.Xml.XmlTextReader _xmlr;
if (String.IsNullOrEmpty(errorMsg))
_xmlr = new System.Xml.XmlTextReader(new StringReader(GetTransferedData(content)));
else
_xmlr = new System.Xml.XmlTextReader(new StringReader(@"<html><body>Error Message:" + errorMsg + "</body></html>"));
iTextSharp.text.html.HtmlParser.Parse(document, _xmlr);
document.Close();
ms.Flush();
byte[] data = ms.ToArray();
Response.Clear();
Response.ClearHeaders();
Response.ClearContent();
Response.Buffer = true;
Response.ContentType = "application/pdf";
Response.BinaryWrite(data);
Response.End();
ms.Close();
}
