选定的单选按钮在 iText.Html2pdf 中不起作用

如何解决选定的单选按钮在 iText.Html2pdf 中不起作用

我正在尝试将以下 HTML 转换为 pdf，它有一个预选的单选按钮，并检查了属性。但它在 iTextSharp 中抛出错误。

<div style='color:#003399;font-style:italic;position:absolute;left:280px;top:170px;'>
<input type='radio' /><label> RD1 </label><br />
<input type='radio' checked /><label> RD2 </label> <br />
<input type='radio' /><label> RD3 </label><br />
</div>

我的 C# 代码是：

 public void createPdf()
        {
            string html = @"C:\Users\rahul\OneDrive\Desktop\new.html";
            HtmlConverter.ConvertToPdf(new FileStream(html,FileMode.Open,FileAccess.Read,FileShare.Read),new FileStream(DEST,FileMode.Create));
           
        } 

我得到的例外是：

iText.Html2pdf.Exceptions.TagWorkerInitializationException: 'Could not instantiate TagWorker-class iText.Html2pdf.Attach.Impl.Tags.InputTagWorker for tag input.'

当radio标签上的checked属性被移除后，它就可以正常工作了...
