asp.net – 反复调用AddImageUrl(url)来汇编pdf文档

就像是：

int pageCount = 0;
     int theId = theDoc.AddImageUrl("https://stackoverflow.com/search?q=abcpdf+footer+page+x+out+of+",true,true);
     //assemble document
     while (theDoc.Chainable(theId))
     {
        theDoc.Page = theDoc.AddPage();
        theId = theDoc.AddImageToChain(theId);
     }
     pageCount = theDoc.PageCount;
     Console.WriteLine("1 document page count:" + pageCount);
     //Flatten document
     for (int i = 1; i <= pageCount; i++)
     {
        theDoc.PageNumber = i;
        theDoc.Flatten();
     }

     //now try again
     theId = theDoc.AddImageUrl("https://stackoverflow.com/questions/1980890/pdf-report-generation",true);
     //assemble document
     while (theDoc.Chainable(theId))
     {
        theDoc.Page = theDoc.AddPage();
        theId = theDoc.AddImageToChain(theId);
     }
     Console.WriteLine("2 document page count:" + theDoc.PageCount);
     //Flatten document
     for (int i = pageCount + 1; i <= theDoc.PageCount; i++)
     {
        theDoc.PageNumber = i;
        theDoc.Flatten();
     }
     pageCount = theDoc.PageCount;

编辑：
似乎基于’猎人’解决方案工作的代码：

static void Main(string[] args)
  {
     Test2();
  }

  static void Test2()
  {

     Doc theDoc = new Doc();
     // Set minimum number of items a page of HTML should contain. 
     theDoc.HtmlOptions.ContentCount = 10;// Otherwise the page will be assumed to be invalid.
     theDoc.HtmlOptions.RetryCount = 10; // Try to obtain html page 10 times
     theDoc.HtmlOptions.Timeout = 180000;// The page must be obtained in less then 10 seconds

     theDoc.Rect.Inset(0,10);  // set up document
     theDoc.Rect.Position(5,15);
     theDoc.Rect.Width = 602;
     theDoc.Rect.Height = 767;
     theDoc.HtmlOptions.PageCacheEnabled = false;

     IList<string> urls = new List<string>();
     urls.Add("https://stackoverflow.com/search?q=abcpdf+footer+page+x+out+of+");
     urls.Add("https://stackoverflow.com/questions/1980890/pdf-report-generation");
     urls.Add("http://yahoo.com");
     urls.Add("https://stackoverflow.com/questions/4338364/recursively-call-addimageurlurl-to-assemble-pdf-document");

     foreach (string url in urls)
        AddImage(ref theDoc,url);

     //Flatten document
     for (int i = 1; i <= theDoc.PageCount; i++)
     {
        theDoc.PageNumber = i;
        theDoc.Flatten();
     }

     theDoc.Save("batchReport.pdf");
     theDoc.Clear();
     Console.Read();

  }


  static void AddImage(ref Doc theDoc,string url)
  {
     int theId = theDoc.AddImageUrl(url,true);
     while (theDoc.Chainable(theId))
     {
        theDoc.Page = theDoc.AddPage();
        theId = theDoc.AddImageToChain(theId); // is this right?
     }
     Console.WriteLine(string.Format("document page count: {0}",theDoc.PageCount.ToString()));
  }

编辑2：遗憾的是,生成pdf文档时多次调用AddImageUrl似乎不起作用…
