您好我通过使用itextsharp解析html来编写一些pdf并且它工作正常但我想在pdf的每个页面上添加页码。为此,我在其中添加带有虚拟文本的标题(稍后我会将其替换为页数)并编写圆顶内容,但内容不会显示..
try
{
Document oNewDocument = new Document(PageSize.A4, 20f, 20f, 30f, 10f);
PdfWriter.GetInstance(oNewDocument, new FileStream(pdfpath + "/" + sSaleInvoicePdf, FileMode.Create));
string content = "Some HTML Content";
List<IElement> parsedHtmlElements = HTMLWorker.ParseToList(new StringReader(contents), styles);
oNewDocument.AddHeader("text","text");
foreach (var htmlElement in parsedHtmlElements)
{
oNewDocument.Add(htmlElement as IElement);
}
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
finally
{
oNewDocument.Close();
}
我在哪里。此代码生成所有html内容但不生成标题文本.. ??

版本5+您必须使用页面事件执行此操作:
Handling header footer page event, itextsharp 5+
在版本5之前,它的工作方式如下:
Document oNewDocument = new Document(PageSize.A4, 20f, 20f, 30f, 10f);
PdfWriter.GetInstance(oNewDocument, new FileStream(pdfpath + "/" + sSaleInvoicePdf, FileMode.Create));
//Create some text to add to the header
Chunk text= new Chunk("my text");
Phrase phHeader = new Phrase();
phHeader.Add(text);
//Assign the Phrase to PDF Header
HeaderFooter header = new HeaderFooter(phHeader, false);
//Add the header to the document
oNewDocument.Header = header;

HeaderFooter hdr = new HeaderFooter(stringvalue, false);
hdr.Border = Rectangle.NO_BORDER;
hdr.Alignment = Element.ALIGN_LEFT;
doc.Header = hdr;
尝试这个不确定你的版本是否支持这个...尝试一下
