將 aspx 轉換為 pdf
[英]Converting aspx to pdf
問題描述
我已經使用 ItextSharp 從 aspx 頁面生成 pdf 文件。
但它在 obj.Parse(se) 中給了我一個錯誤，其中 se 是字符串讀取器，它采用以下路徑：-
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
我被這個問題困住了。
請幫助並給出建議。
謝謝你

這是一個對我有用的例子。 有一些代碼，但它顯示了您可以利用 css 之類的方法。 希望能幫助到你。
private void ExportToPDF()
{
string s = "<table><td><tr>First<b>row</b></tr></td></table>";
Document document = new Document(PageSize.LETTER, 30, 30, 60, 35);
MemoryStream msReport = new MemoryStream();
string strHTMLpath = Server.MapPath("../myHTML.html");
string strPDFpath = Server.MapPath("../myPDF.pdf");
try
{
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
StreamWriter strWriter = new StreamWriter(strHTMLpath, false, Encoding.UTF8);
strWriter.Write(s.ToString());
strWriter.Close();
strWriter.Dispose();
iTextSharp.text.html.simpleparser.StyleSheet styles = new iTextSharp.text.html.simpleparser.StyleSheet();
styles.LoadTagStyle("ol", "leading", "16,0");
PdfWriter.GetInstance(document, new FileStream(strPDFpath, FileMode.Create));
document.Add(new Header(iTextSharp.text.html.Markup.HTML_ATTR_STYLESHEET, "Style.css"));
document.Open();
ArrayList objects;
styles.LoadTagStyle("li", "face", "garamond");
styles.LoadTagStyle("span", "size", "8px");
styles.LoadTagStyle("body", "font-family", "times new roman");
styles.LoadTagStyle("body", "font-size", "10px");
document.NewPage();
objects = iTextSharp.text.html.simpleparser.
HTMLWorker.ParseToList(new StreamReader(strHTMLpath, Encoding.Default), styles);
for (int k = 0; k < objects.Count; k++)
{
document.Add((IElement)objects[k]);
}
}
catch (Exception ex)
{
throw ex;
}
finally
{
document.Close();
Response.Write(strPDFpath);
Response.ClearContent();
Response.ClearHeaders();
Response.AddHeader("Content-Disposition", "attachment; filename=myFileName.pdf");
Response.ContentType = "application/octet-stream";
Response.WriteFile(strPDFpath);
Response.Flush();
Response.Close();
File.Delete(strPDFpath);
}
}
aspx頁面保存為pdf
