为了使用Aspose.Pdf for.Net在现有的PDF文件中填充表单字段,要使用到Form class。这个类提供了FillField方法允许您填补不同的字段。例如,你可以使用这种方法填写一个文本字段或设置复选框和comob框值。首先,您需要创建一个输入和输出PDF文件参数的Form class类对象,然后调用FillField方法。在那之后,您需要调用Save方法来保存输出PDF文件。

C#

//open document
Aspose.Pdf.Facades.Form pdfForm = new Aspose.Pdf.Facades.Form("input.pdf", "output.pdf");
//Fill the field "Name" with "Mike".
pdfForm.FillField("Name", "Mike");
//Choose the field "Gender" with "Male".
pdfForm.FillField("Gender", "Male");
//Fill the field "Telephone".
pdfForm.FillField("Telephone", "888.277.6734");
//Fill the field "Address".
pdfForm.FillField("Address", "41, Lily Street, Hurstville, NSW, 2220 Australia ");
//Choose the item "GradeTwo" of the Combo field "Grade".
pdfForm.FillField("Grade", "GradeTwo");
//use case for unchecking the checkbox "Lodging".
pdfForm.FillField("Lodging", "Off");
//save updated PDF
pdfForm.Save();
