hiqpdf - asp.net - 如何修改代碼以捕獲div

Question

這是我爲hiqpdf下載的C＃，但我不確定如何修改它，以便它能夠與我的html一起工作？我的asp.net c＃工作表textBoxUrl出現錯誤，但我不知道我應該使用什麼名稱空間來抓住這個或我是否需要替換這個文本？

C＃代碼：

using HiQPdf; 

protected void Print_Button_Click(object sender, EventArgs e) 
{ 

    // create the HTML to PDF converter 
    HtmlToPdf htmlToPdfConverter = new HtmlToPdf(); 

    // select the HTML element to be converted to PDF 
    htmlToPdfConverter.ConvertedHtmlElementSelector = 
            textBoxConvertedHtmlElementSelector.Text; 

    // convert URL to a PDF memory buffer 
    string url = textBoxUrl.Text; 

    byte[] pdfBuffer = htmlToPdfConverter.ConvertUrlToMemory(url); 

    // inform the browser about the binary data format 
    HttpContext.Current.Response.AddHeader("Content-Type",application/pdf"); 

    // let the browser know how to open the PDF document 
    HttpContext.Current.Response.AddHeader("Content-Disposition", 
       String.Format("attachment; filename=ConvertHtmlPart.pdf; 

         size ={ 0} 
    ", 
     pdfBuffer.Length.ToString())); 

    // write the PDF buffer to HTTP response 
    HttpContext.Current.Response.BinaryWrite(pdfBuffer); 

    // call End() method of HTTP response 
    // to stop ASP.NET page processing 
    HttpContext.Current.Response.End(); 

}

的textBoxUrl是TextBox控件。您應該將其替換爲源網址。

例如用於「#page」選擇器的bbc站點。

using HiQPdf; 

protected void Print_Button_Click(object sender, EventArgs e) 
{ 

// create the HTML to PDF converter 
HtmlToPdf htmlToPdfConverter = new HtmlToPdf(); 

// select the HTML element to be converted to PDF 
htmlToPdfConverter.ConvertedHtmlElementSelector = "#page"        

// convert URL to a PDF memory buffer 
string url = "http://www.bbc.com/"; 

byte[] pdfBuffer = htmlToPdfConverter.ConvertUrlToMemory(url); 

// inform the browser about the binary data format 
HttpContext.Current.Response.AddHeader("Content-Type",application/pdf"); 

// let the browser know how to open the PDF document 
HttpContext.Current.Response.AddHeader("Content-Disposition", 
      String.Format("attachment; filename=ConvertHtmlPart.pdf; 

        size ={ 0} 
", 
    pdfBuffer.Length.ToString())); 

// write the PDF buffer to HTTP response 
HttpContext.Current.Response.BinaryWrite(pdfBuffer); 

// call End() method of HTTP response 
// to stop ASP.NET page processing 
HttpContext.Current.Response.End(); 

}
