我正在尝试通过单击链接按钮的代码导出我的pdf中的数据库表内容我在链接按钮上调用此函数
public void EXportCaseAsText(int caseid)
{
DateTime pubdate = new DateTime();
// System.IO.MemoryStream msReport = new System.IO.MemoryStream();
int pageno = 1, questionno = 1;
int count = BlFactory.CipCaseWorkflowItemBl.LoadWorkflowForCase(caseid).Count;
Font HeaderFont = FontFactory.GetFont(FontFactory.TIMES_ROMAN, 14, Font.BOLD, iTextSharp.text.Color.RED);
Font OptionsFont = FontFactory.GetFont(FontFactory.TIMES_ROMAN, 10, Font.BOLD, iTextSharp.text.Color.BLACK);
Font TrueFont = FontFactory.GetFont(FontFactory.TIMES_ROMAN, 10, Font.UNDERLINE, iTextSharp.text.Color.BLUE);
Font dataFont = FontFactory.GetFont(FontFactory.TIMES_ROMAN, 10, Font.NORMAL, iTextSharp.text.Color.BLACK);
Font datefont = FontFactory.GetFont(FontFactory.TIMES_ROMAN, 14, Font.BOLD, iTextSharp.text.Color.BLUE);
if (count > 0)
{
try
{
Document document = new Document(PageSize.A4);
//PdfWriter.GetInstance(document, new FileStream("D:\\RCMS\\Acr3S.Cmf.Web\\bin\\Debug\\my.pdf", FileMode.Create));
PdfWriter writer = PdfWriter.GetInstance(document, Response.OutputStream);
document.Open();
DateTime pub = getCasePublishedDate(caseid);
if (pub.ToShortDateString().Equals("1/1/0001"))
{
Paragraph paragraph = new Paragraph(new Paragraph("Not yet published",datefont));
paragraph.Alignment = Element.ALIGN_CENTER;
document.Add(paragraph);
}
else
{
string date = DateFormatter.GetFormattedDate(pub);
Paragraph paragraph = new Paragraph(new Paragraph(date, datefont));
paragraph.Alignment = Element.ALIGN_CENTER;
document.Add(paragraph);
}
for (int i = 0; i < count; i++)
{
CipCaseWorkflowItem item = (new NHibernate.DebugHelpers.CollectionProxy<Acr3S.Core.Domain.CipCaseWorkflowItem>

document.Add(par);

ArrayList objects = HTMLWorker.ParseToList(new StringReader(textItem.ContentElement.Text), styles);

}
case "History":

//par.Add(chunk);
document.Add(par);

for (int k = 0; k < objects.Count; ++k)

}
break;
}
case "Discussion":

//par.Add(chunk);
document.Add(par);

}
}
break;
}
}
}
document.Close();
Response.AddHeader("content-disposition", "attachment;filename=" + getCaseName(caseid) + ".pdf");
Response.ContentType = "application/pdf";
Response.End();
}
catch (DocumentException de)
{
Console.Error.WriteLine(de.Message);
}
}
}
问题是某些时候讨论数据没有在pdf中显示某些历史数据没有在pdf中显示有时案例点数据没有以PDF格式显示而所有数据都存在于表中
我不知道为什么会发生这种情况
答案 0 :(得分：1)
替换
document.Add(par);
StyleSheet styles = new StyleSheet();
ArrayList objects = HTMLWorker.ParseToList(new StringReader(textItem.ContentElement.Text), styles);
for (int k = 0; k < objects.Count; ++k)
{
document.Add((IElement)objects[k]);
}
通过
//实施新守则：
document.Add(par);
StyleSheet styles = new StyleSheet();
string tempText = textItem.ContentElement.Text;
tempText = tempText.Replace("\"", """);
ArrayList objects = HTMLWorker.ParseToList(new StringReader(tempText), styles);
for (int k = 0; k < objects.Count; ++k)
{
document.Add((IElement)objects[k]);
}
这样可以正常工作......
