iTextSharp +OnEndPage
我正在尝试重写 OnEndPage 事件，但收到错误消息，指出没有找到合适的方法来重写
public override void OnEndPage(PdfWriter wri, Document doc)
{
PdfPTable table = new PdfPTable(1);
table.TotalWidth = doc.PageSize.Width - doc.LeftMargin - doc.RightMargin;
PdfPTable table2 = new PdfPTable(2);
PdfPCell cell2 = new PdfPCell(new Phrase("Test Top"));
cell2.Colspan = 2;
table2.AddCell(cell2);
cell2 = new PdfPCell(new Phrase("\nTitle", new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 16, iTextSharp.text.Font.BOLD | iTextSharp.text.Font.UNDERLINE)));
cell2.HorizontalAlignment = Element.ALIGN_CENTER;
cell2.Colspan = 2;
table2.AddCell(cell2);
PdfPCell cell = new PdfPCell(table2);
table.AddCell(cell);
table.WriteSelectedRows(0, -1, doc.LeftMargin, doc.PageSize.Height - 37, wri.DirectContent);
}
Is 轻轻地坐落在两个按钮调用之间...我做错了什么吗？如果是的话，如果可能的话，是否可以提供包含整个 PDR/标头生成的完整源代码的示例？我没找到他们，我开始发疯了，哈哈，
谢谢你的帮助
I'm trying to override the OnEndPage event but I get the error message that there is no suitable method found to override
public override void OnEndPage(PdfWriter wri, Document doc)
{
PdfPTable table = new PdfPTable(1);
table.TotalWidth = doc.PageSize.Width - doc.LeftMargin - doc.RightMargin;
PdfPTable table2 = new PdfPTable(2);
PdfPCell cell2 = new PdfPCell(new Phrase("Test Top"));
cell2.Colspan = 2;
table2.AddCell(cell2);
cell2 = new PdfPCell(new Phrase("\nTitle", new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 16, iTextSharp.text.Font.BOLD | iTextSharp.text.Font.UNDERLINE)));
cell2.HorizontalAlignment = Element.ALIGN_CENTER;
cell2.Colspan = 2;
table2.AddCell(cell2);
PdfPCell cell = new PdfPCell(table2);
table.AddCell(cell);
table.WriteSelectedRows(0, -1, doc.LeftMargin, doc.PageSize.Height - 37, wri.DirectContent);
}
Is gently nestled between two button calls... Am I doing something wrong? If I am, and if possible, can a example with full source for the entire PDR/Header generation be provided? I've had no luck finding them and I'm starting to go mad, haha
Thanks for any help

创建一个继承自 PdfPageEventHelper 的类，覆盖 OnStartPage 和 OnEndPage 并将该类的实例分配给 PdfWriter 实例的 PageEvent。
希望这有帮助
Create a class that inherits from PdfPageEventHelper override the OnStartPage and OnEndPage and assign the instance of that class to the PageEvent of PdfWriter instance.
Hope this helps
