在很多时候需要预先创建一个带多个字段PDF模板，然后客户可以在这些字段下填充数据，PDFKit.NET可以帮助客户在已有的PDF模板文件里填充数据，当然这些数据可以是从数据读取，也可以是手动填充，下面的事例主要介绍如何从数据库读取出数据并填充到PDF模板里的字段里，具体代码如下：

1 string[] names = {  "Robert", "Stam",
 2                     "Frank", "Rem",
 3                     "Marnix", "van Valen",
 4                     "Marco", "Kesseler" };
 5
 6 //open the template document
 7 using (FileStream templateStream = new FileStream(@"..\..\template.pdf", FileMode.Open, FileAccess.Read,

FileShare.Read))
 8 {
 9     Document templateDoc = new Document(templateStream);
10
11     Page templatePage = templateDoc.Pages[0];
12     TextField firstName = templateDoc.Fields["FirstName"] as TextField;
13     TextField lastName = templateDoc.Fields["LastName"] as TextField;
14
15     //make sure all widgets on this page will be flattened
16     foreach (Widget widget in templatePage.Widgets)
17     {
18         widget.Persistency = WidgetPersistency.Flatten;
19     }
20
21     // create the result document
22     Document outputDocument = new Document();
23
24     for (int i = 0; i < names.Length; i += 2)
25     {
26         //set the field info in the template page.
27         firstName.Value = names[i];
28         lastName.Value = names[i + 1];
29
30         //append the cloned page to the output.
31         outputDocument.Pages.Add(templatePage.Clone());
32     }
33
34     //write result to disk.
35     using (FileStream outFile = new FileStream(@"..\..\appendTemplate.pdf", FileMode.Create, FileAccess.Write))
36     {
37         outputDocument.Write(outFile);
38     }
39 }
