LoadFromHtml error handle

[af2580]

Hi
I have bunch of URLs needed to be printed as PDF, so I'm using spire.
My question is how I can handle error if url indicates download page not typical web page.
if I type this url, download dialog is popped up automatically.
1. is there any way I can just download and save it using loadfromhtml?
2. if there is no way to do it, how I can handle this error?

Hello,

Thanks for your inquiry. When using loadfromhtml, it is not allowed to load a download page. In this case, you could save the attachment like below. Hope it is helpful to you.

Code: Select all

            using (WebClient webClient = new WebClient())
            {
                byte[] data = webClient.DownloadData(download url);
                //byte to file
                FileStream fs = new FileStream(@"f:\test\result.pdf", FileMode.Create, FileAccess.Write);
                fs.Write(data, 0, data.Length);
                fs.Flush();
            }

Hi
I have one more inquiry.
How can we know this url is whether webpage or download page?
is there any return value for loadfromHtml or DownloadData?

Hello,

Thanks for your reply. You could first sort the URLs into two group by regex and then deal with them separately.
