当导致错误时，我收到以下消息。

此错误标记第602行，即该部分代码“pdfDoc.Open（）”的行

我猜不知道某些东西没有妥善处理。

如果有人有一个很棒的想法：D

Answer 1

由于您未在代码中创建新实例，因此您似乎可以重复使用Document pdfDoc对象。这不起作用，iText Document对象只是一次性的。

因此，添加

pdfDoc = New Document

前

Dim pdfWrite As PdfWriter = PdfWriter.GetInstance(pdfDoc, New FileStream("\\verkoop\offerte v2\Offerte " & offertenummer2 & "-" & offertenummer & " " & TextBox2.Text & ".pdf", FileMode.Create))

VB.net itextsharp创建第二个PDF会导致错误
