我们需要获取包含特定PdfTextField的Pdf页面,我们该怎么做?
代码:
PdfDocument document = PdfReader.Open("C:\\filex.pdf", PdfDocumentOpenMode.Modify);
// Get the root object of all interactive form fields
PdfAcroForm form = document.AcroForm;
// Get all form fields of the whole document
PdfAcroField.PdfAcroFieldCollection fields = form.Fields;
PdfTextField textfield1= (PdfTextField)fields["textfield1"];
//how to get the correct page reference respect the especified field?
PdfPage page = textfield1.Owner.Pages[???];
答案 0 :(得分:0)
最后我们解决了它创建这个功能:
protected int PaginaCampo(string campofirma, PdfDocument document)
{
for (int i = 0; i < document.Pages.Count; i++)
{
PdfAnnotations anotations = document.Pages[i].Annotations;
for (int j = 0; j < anotations.Count; j++)
{
if (anotations[j].Title != campofirma) continue;
return i;
}
}
return -1;
}
不是最好的解决方案,但它有效...如果有人添加更好的解决方案,我们会给他/她正确的答案
