问题描述

我尝试从3天开始制作一份pdf文档,我将不胜感激。

I try from 3 day to find way to make one pdf document, and I will appreciate any help.

我有几个表格字段可以访问并填写否问题。在这个字段下面我想放置动态创建的表。此表可以足够长,可以在多个页面上。这是我的问题。我不能将这个表添加到同一页面上,并在其下方使用表单fiels。我找到合并pdf文件的示例。现在我有这种情况。

I have few form fields which access and fill with no problem. Below of this fields I want to place dynamically created table. This table can be long enough to be on more than one page. And here is my problem. I can`t add this table on the same page with form fiels just below them. I find example which merge pdf files. And now I have this scenario.


  1. 制作一个包含填写表格字段的pdf

  2. 制作pdf pdfTable总是只有一个页面,但内容更长

  3. 制作从前两个合并的pdf。在第一页填写表单字段,在第二页是我的pdfTable。

我只想要从表格字段和表格开始第一页并继续下一页。

I just want to have form fields and table which starts from first page and continue on some next pages.

我发布的代码有点乱,但是......

推荐答案

您的代码确实是一团糟。我会复制/粘贴它,但请理解我不是C#开发人员。我只知道Java,我从内到外知道iText(我是它的原始开发人员)。

Your code is indeed a mess. I'll copy/paste it but please understand that I'm not a C# developer. I only know Java and I know iText inside-out (I'm its original developer).

你在第一部分犯的重大错误代码,正在引入文档。没有必要这样做。请阅读我的书的并查看。

The major mistake you made in the first part of your code, is introducing Document. There's no need for that. Please read chapter 6 of my book and take a look at the C# examples.

您在第二部分中犯的主要错误是使用 ColumnText 意味着您想要控制布局,但不知道如何处理该控件。如果您使用 ColumnText ,则需要询问列是否已消耗所有内容。如果没有,您需要自己创建一个新页面。我在本书的中对此进行了解释。

The major mistake you made in the second part is using ColumnText meaning you want to take control over the layout, but not knowing how to deal with that control. If you use ColumnText, you need to ask the column if all content was consumed. If not, you need to create a new page yourself. This is all explained in chapter 3 of my book.

第三部分看起来还不错(据我所知C#)。

The third part looks OK (as far as I understand C#).

我写了我的书,以便人们可以从一开始就编写正确的代码来节省时间。我没有写我的书,所以我必须在StackOverflow上复制/粘贴它们; - )

I wrote my books so that people can save time by writing correct code from the start. I didn't write my books so that I have to copy/paste them on StackOverflow ;-)
