how can i convert a url address like "http://google.com" to pdf?

[tmzl]

I want to convert a link to pdf, but threw exception。"not found Syncfusion.Pdf.PdfDocument Syncfusion.HtmlConverter.HtmlToPdfConverter.Convert(System.String)"

“System.MissingMethodException”类型的未经处理的异常在 mscorlib.dll 中发生 

其他信息: 找不到方法:“Syncfusion.Pdf.PdfDocument Syncfusion.HtmlConverter.HtmlToPdfConverter.Convert(System.String)”。

public void HtmlToFile()
        {
            //Initialize HTML to PDF converter
            Thread t = new Thread(CreateDocument);
            t.SetApartmentState(ApartmentState.STA);
            t.Start();
            t.Join();
        }
 
        public void CreateDocument()
        {
            HtmlToPdfConverter htmlConverter = new HtmlToPdfConverter();
            //Convert HTML to PDF document
 
            PdfDocument document = htmlConverter.Convert("http://www.google.com");
 
            //Save and close the PDF document
 
            document.Save("Output.pdf");
 
            document.Close(true);
        }
