HI,

I am downloading a files from WSS using the webclient.downloaddata method as below:

WebClient objhelper= new WebClient();

                                           

  objhelper.Credentials = source_credentials;

                                   byte[]   data = objhelper.DownloadData(FileUrl);

i have also specified the credentials. Most strange issue is it is working for some files and randomly throws this issue on objhelper.DownloadData(FileUrl) line.

Please suggest

Hi varinder,

Please try to set UseDefaultCredentials to true. The following code snippet for your reference:

WebClient objhelper= new WebClient();
                                            
objhelper.Credentials = source_credentials;

objhelper.UseDefaultCredentials = true;

byte[] data = objhelper.DownloadData(FileUrl);

If the issue still exists, please use an admin user to download the files from SharePoint.

Best Regards,

Dennis
