iTextSharp 根据模板生成PDF

一下载此软件Adobe Acrobat X Pro 编辑PDF，将控件拖拽到页面，然后使用下面工作方法生成模板。

提示在生成过程中看不到替换值问题，其实就是模板设置字体问题。换个字体就好了

里面有2个方法 处理中文那个很重要，对于我们中文用户来说。其中iTextAsianCmaps.dll是不需要VS里添加引用的。是在代码调用的时候动态添加

关于iTextAsianCmaps.dll,iTextSharp.dll,iTextAsian.dll下载问题在下面链接里面查看操作

关于效果

 

 

 

 

 

代码如下，只是测试需要对同行有些帮助
