我如何枚舉在PDF文件中的所有字段iTextSharp的

Question

比方說，我已經加載使用iTextSharp的PDF文件：

PdfStamper p = GetDocument(); 
AcroFields af = ps.AcroFields; 

我如何從af文檔的所有字段名的列表？

Answer 1

AcroFields af = ps.AcroFields; 

     foreach (var field in af.Fields) 
     { 
      Console.WriteLine("{0}, {1}", 
       field.Key, 
       field.Value); 
     } 

Answer 2

foreach (DictionaryEntry entry in af.Fields) { 
    Console.WriteLine(entry.Key +" " +entry.Value); 
} 

Answer 3

這可能只是我，但我沒有得到.value的了。

foreach (var field in af.Fields) 
{ 
    Console.WriteLine(field.Key +" "+ af.GetField(field.Key)); 
} 

Answer 4

PdfReader pdfReader = new PdfReader("c:\\ABC.pdf"); 

string TempFilename = Path.GetTempFileName(); 

AcroFields pdfFormFields = pdfReader.AcroFields; 

foreach (KeyValuePair<string, AcroFields.Item> kvp in pdfFormFields.Fields) 
{ 
     string fieldName = kvp.Key.ToString(); 
     string fieldValue = pdfFormFields.GetField(kvp.Key.ToString()); 
     Console.WriteLine(fieldName + " " + fieldValue); 
} 

pdfReader.Close();
