C# 生成PDF代码示例二

本文给出使用iTextSharp来生成pdf文档的方法。

面是我根据实际情况编写的代码，包含如下：

1、段落

2、表格

3、字体格式化

运行此代码需要的类库：

itextsharp.dll,itext-hyph-xml.dll,iTextAsian.dll和ICSharpCode.SharpZipLib.dll

itextsharp项目地址：http://sourceforge.net/projects/itextsharp/

示例代码,/Files/hudonglin/PDFMake.rar示例代码也贴在下面了

本代码支持中文字符，下面直接上代码
