我有一张卡片清单，我必须为每张卡号创建声明。现在我为每个数字生成单独的pdf文件，每个数字都有不同的页眉页脚参数。现在我想在单个pdf文件中使用所有这些语句。但是如果我在循环中调用pdffooter，它就不起作用了。 如何在每个卡号的pdf中使用不同的页眉和页脚？
protected void ReportGenerate_Click(object sender, EventArgs e)
{

try
{
cResult = oCommonMethod.GetCardNoList(ddl_BRANCH.SelectedValue);
int cnt = 0;
foreach (DataRow dr in cResult.DataTable.Rows)
{
cnt++;
pdfDoc = new Document();
string path = Server.MapPath("PDFs");
Document doc = new iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 10, 10, 270f, 140f);
PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(path + "/Doc" + cnt + ".pdf", FileMode.Create));
...........
dtStatement = oCommonMethod.GetCardStatement(dr["CARDNO"].ToString(), dr["BRCOD"].ToString(), dr["ACNO"].ToString(), dr["ACTCOD"].ToString(), dr["CARD_TYPE"].ToString(), sday);
previous_balance = oCommonMethod.GetPreviousBalance(dr["BRCOD"].ToString(), dr["ACNO"].ToString(), dr["ACTCOD"].ToString(), sday);
//here I call the pdffooter passing argument
writer.PageEvent = new PDFFooter(CARDNO, CREDIT_LIMIT, ACTITLE, ADD1, ADD2, AVAILABLE_LIMIT, AVAILABLE_CASH_LIMIT, STATEMENT_DATE, DUE_DATE, MIN_DUE, outstanding);
doc.Open();
int stmntcnt = dtStatement.Rows.Count;
int flag = 0;
//double sum = 0;
foreach (DataRow dt in dtStatement.Rows)
{
..........
//pdf design between header and footer here
//////
doc.Add(table);
}
}
