我想使用给定代码生成多个发票和单个发票。当用户在此函数GenInvoice(int clientId, string InvoiceNum, bool SinglePage) SinglePage= true中传递值时，代码将在分页后在同一文档中打印多个发票。
问题
当我在我的函数中发送多个发票号时，此函数生成并且singlepage为true，然后此函数不会在同一文档中生成多个pdf。我将值传递给函数
GenInvoice(1362, "85561,85231",true);
我的代码低于
public void GenInvoice(int clientId, string InvoiceNum, bool SinglePage)

string[] arg = InvoiceNum.Split(',');
InOnePdf = SinglePage;

答案 0 :(得分：2)
在iTextSharp中，您只有一个文档和多个页面。所以删除doc.Close（）;在Newpage（）之后;把它放在循环外面。
doc.NewPage();
doc.Close(); // remove this: it will stop any further writing
您也只在循环的第一次迭代中创建一个新表。我不确定为什么。我以为你想要为每张发票买一张新桌子。
table = new PdfPTable(8); // move outside of the if (TotalCount == 1)
同时删除Try / Catch以允许显示任何错误。
// this stuff should be outside of the loop too
PdfWriter wri = PdfWriter.GetInstance(doc, new FileStream(pdfFilePath, FileMode.Create));
doc.Open();
