C#代码实现PDF文档操作类
本文纯干货，贴上PDF文档操作类C#代码，需要添加iTextSharp.dll引用才可以正常通过编译。
废话不多说了，直接给大家贴代码了。
代码如下：
usingSystem.IO;
usingiTextSharp.text;
usingiTextSharp.text.pdf;
namespaceDotNet.Utilities
{
///<summary>

//------------------------------------调用--------------------------------------------
//PDFOperationpdf=newPDFOperation();
//pdf.Open(newFileStream(path,FileMode.Create));
//pdf.SetBaseFont(@"C:\Windows\Fonts\SIMHEI.TTF");
//pdf.AddParagraph("测试文档（生成时间："+DateTime.Now+"）",15,1,20,0,0);
//pdf.Close();
//-------------------------------------------------------------------------------------
