我有它的单选按钮和文本框,但似乎无法让复选框工作.
在这种情况下,我还确认了复选框名称,“Q7b”在acrobat文档中是正确的,可以使用以下代码在表单上找到它

private string getfieldnames(AcroFields fields)
{
    StringBuilder sb = new StringBuilder();

    foreach (string key in fields.Fields.Keys)
    {

        sb.Append(key + Environment.NewLine);
    }
    return sb.ToString();

}

我正在使用的代码更新复选框在下面

using (MemoryStream pdfFlat = new MemoryStream())
{

    PdfReader pdfReader = new PdfReader(strPath);
    PdfStamper pdfStamp = new PdfStamper(pdfReader,pdfFlat);
    AcroFields fields = pdfStamp.AcroFields;

    //textfields
    fields.SetField("Initiating_Doctor","Doctor A");
    fields.SetField("Speciality","Surgeon");

    //Radiobuttons
    fields.SetField("PRELIM_Q1","Yes");
    fields.SetField("PRELIM_Q2","No");
    fields.SetField("PRELIM_Q3","No");
    fields.SetField("PRELIM_Q4","No");

    //checkBox - Set the checkBox to checked but this does not work.
    fields.SetField("Q7b","Yes");

    pdfReader.Close();
    pdfStamp.FormFlattening = true;
    pdfStamp.FreeTextFlattening = true;
    pdfStamp.Writer.CloseStream = false;
    pdfStamp.Close();
}

任何帮助将不胜感激.
