我正在尝试使用我的数据库中的所有详细信息生成PDF。这非常有效...直到数据库中插入了更多行数据，然后我的行一直运行到页面的末尾，然后突然消失。我一直在寻找互联网上的解决方案，如何让我的行显示在多个页面上，但我没有运气。在PDFSharp的论坛中没有关于这个主题的支持（至少，不是我能找到的），我真的需要这个工作。任何帮助都会受到极大的赞赏！
以下是我生成PDF的代码:(代码有效，直到我有很多行。）
public void PrintPDFDisplayingLogInformation(DataGridView dataPayments)

string lastPaidAmount = null;
string arrears = null;
string month = DateTime.Now.ToString("MM");
string year = DateTime.Now.Year.ToString();
ds = paymentService.RetrieveFullPaymentLogForPDF();

pdf.Info.Title = "Payments This Month";

您正在使用PDFsharp。使用PDFsharp，您负责分页符。再次调用AddPage（）以启动新页面并开始在页面顶部写入行。
另一个答案中链接的Invoice示例适用于MigraDoc。 MigraDoc自动处理分页符。切换到MigraDoc可能是获取跨越多个页面的表的更简单方法。
在PDFsharp论坛上多次询问（和回答）这样的问题。
