如何将多个网页转换为一个pdf文档？(How do I convert several web pages into one pdf document?)

public FileResult Download() 
{ 

    var doc = new EO.Pdf.PdfDocument(); 
    EO.Pdf.HtmlToPdf.ConvertUrl("http://www.google.com/", doc); 

    var ms = new MemoryStream();     
    doc.Save(ms); 

    ms.Position = 0; 

    return new FileStreamResult(ms, "application/pdf") 
               { 
                   FileDownloadName = "download.pdf"
               }; 
}
 
 如果可能的话，请您展示如何扩展上面的代码，以便能够将多个网页转换成一个pdf文档？ 
 
 棘手的部分是我们不知道用户可能尝试转换的页面。 
 
 因此，如上面的代码所示，对网页进行硬编码并没有帮助我们。 
 
 任何帮助是极大的赞赏。 
 
//Create a new PdfDocument object
var doc = new EO.Pdf.PdfDocument();

//Convert two ore more different pages into the same PdfDocument

EO.Pdf.HtmlToPdf.ConvertUrl("c:\\1.html", doc);

EO.Pdf.HtmlToPdf.ConvertUrl("c:\\2.html", doc);
 
 最新代码： 
 
public FileResult Download() 
{ 
    var doc = new EO.Pdf.PdfDocument(); 

foreach(var url in passedUrls)  
{ 
EO.Pdf.HtmlToPdf.ConvertUrl(url, doc);   
doc.Save(ms);   
}


    ms.Position = 0; 

    return new FileStreamResult(ms, "application/pdf") 
               { 
                   FileDownloadName = "download.pdf"
               }; 
}
 
 亚当的最新消息（谢谢先生） 
 
public FileResult Download() 
{ 

var documents = new List<EO.Pdf.PdfDocument>(); 
foreach(var url in passedUrls) 
{ 
    var doc = new EO.Pdf.PdfDocument(); 
    EO.Pdf.HtmlToPdf.ConvertUrl(url, doc); 
    documents.Add(doc); 
} 

EO.Pdf.PdfDocument mergedDocument = EO.Pdf.PdfDocument.Merge(documents.ToArray()); 
}
 
 希望其他人发现这些代码很有用。 

public FileResult Download() 
{ 

    var doc = new EO.Pdf.PdfDocument(); 
    EO.Pdf.HtmlToPdf.ConvertUrl("http://www.google.com/", doc); 

    var ms = new MemoryStream();     
    doc.Save(ms); 

    ms.Position = 0; 

    return new FileStreamResult(ms, "application/pdf") 
               { 
                   FileDownloadName = "download.pdf"
               }; 
}
 
Can you please show if possible, how to extend the code above to be able to convert several web pages into one pdf document?
 
The tricky part is that we don't know what pages a user is likely to attempt to convert.
 
So, hardcoding the webpages as the code above shows isn't helping us.
 
Any help is greatly appreciated.
 
//Create a new PdfDocument object
var doc = new EO.Pdf.PdfDocument();

//Convert two ore more different pages into the same PdfDocument

EO.Pdf.HtmlToPdf.ConvertUrl("c:\\1.html", doc);

EO.Pdf.HtmlToPdf.ConvertUrl("c:\\2.html", doc);
 
Latest code:
 
public FileResult Download() 
{ 
    var doc = new EO.Pdf.PdfDocument(); 

foreach(var url in passedUrls)  
{ 
EO.Pdf.HtmlToPdf.ConvertUrl(url, doc);   
doc.Save(ms);   
}


    ms.Position = 0; 

    return new FileStreamResult(ms, "application/pdf") 
               { 
                   FileDownloadName = "download.pdf"
               }; 
}
 
Latest from Adam (thank you sir)
 
public FileResult Download() 
{ 

var documents = new List<EO.Pdf.PdfDocument>(); 
foreach(var url in passedUrls) 
{ 
    var doc = new EO.Pdf.PdfDocument(); 
    EO.Pdf.HtmlToPdf.ConvertUrl(url, doc); 
    documents.Add(doc); 
} 

EO.Pdf.PdfDocument mergedDocument = EO.Pdf.PdfDocument.Merge(documents.ToArray()); 
}
 
Hopefully, others find these codes useful.
