利用Adobe LiveCycle ES2创建PDF模板，并用C#替换模板中的Acrobat 控件的值

     近段时间，客户有个需求就是有几种60多页的PDF文档，之前的做法是用Word结合Excel的方式，很多东西都是靠人工眼力校对，效率和准确度都得不到保证，故采取编程的方式帮助用户提高效率，具体的实现过程如下：

 

准备工作：安装Acrobat，具体可以上Adobe的官网上下载

 

Step1：安装Acrobat X，这里安装是10版本，现在应该有更新的版本了

      

 

Step2：打开Adobe LiveCycle ES2:

 

Step3:打开或新建一个文档，插入一个TextBox：

 

Step4 ：依次选择Custom，设置Border：none；背景为Solid

 

 

最后一步比较重要，每一个TextBox的Name一定要设置得不一样

 

下面的一段代码是用C#代码替换我们设置的TextBox里面的文本：

 

 1   using ( var existingFileStream =  new FileStream(fileNameExisting, FileMode.Open))
 2          using ( var newFileStream =  new FileStream(fileNameNew, FileMode.Create))
 3         {
 4 
 5              //  Open existing PDF  
 6               var pdfReader =  new PdfReader(existingFileStream);
 7 
 8              //  PdfStamper, which will create  
 9              PdfStamper stamper =  new PdfStamper(pdfReader, newFileStream);
10              var form = stamper.AcroFields;
11              var fieldKeys = form.Fields.Keys;
12              string strFieldValue =  string.Empty;
13              // int i = 0;
14               if (fileNameExisting.Contains( " SetupPackage_16_ANZV2.pdf ") || fileNameExisting.Contains( " SetupPackage_16_ANZV2_03.pdf ") || fileNameExisting.Contains( " SetupPackage_16_ANZV2_04.pdf ") || fileNameExisting.Contains( " SetupPackage_16Company_ANZV2 ") || fileNameExisting.Contains( " SetupPackage_10_ATOTrusteeDeclaration.pdf "))
15             {
16                  string imgRightPath =HttpContext.Current.Server.MapPath( " ~/nnfunds/template/img/imgRight.jpg ");
17                  string imgSignaturePath = HttpContext.Current.Server.MapPath( " ~/nnfunds/template/img/imgSignature.jpg ");
18                  string imgDatePath = HttpContext.Current.Server.MapPath( " ~/nnfunds/template/img/imgDate.jpg "); // imgDate
19                   foreach ( string fieldKey  in fieldKeys)
20                 {
21                      if (fieldKey.Contains( " imgRight ") || fieldKey.Contains( " imgSignature ") || fieldKey.Contains( " imgDate "))
22                     {
23                         iTextSharp.text.Image instanceImg = iTextSharp.text.Image.GetInstance(imgRightPath);
