Hi Prerana,
I am using a different method as follows. I haven't added any Meta Data to
the photos (as that isn't important to my use case) but I guess there
should be a way to add it. It will be worth you taking a look. My code is
below. I have a question for you as I am also at my wits end! The code
below uses an Access Token that I get from OAuth 2.0 Playground. This
works but I need to set up a refresh token in my own app so that I can get
a new access token when the current one expires. I have tried this for a
few hours and as Picasa hasn't been updated like the other APIs I can't get
it to work! Would you mind posting your code to help me please. Are you
using a service account or a web application account to get the access
token? Your help is appreciated and I hope the code below helps you.
using Google.GData.Photos;
using Google.GData.Client;
using Google.GData.Extensions;
using Google.GData.Extensions.Location;
GAuthSubRequestFactory authFactory = new
GAuthSubRequestFactory("lh2", "my-app");
authFactory.Token = "Token taken from Playground";
PicasaService service = new
PicasaService(authFactory.ApplicationName);
service.RequestFactory = authFactory;
Uri postUri = new
Uri(PicasaQuery.CreatePicasaUri("default", AlbumID));
System.IO.FileInfo fileInfo = new
System.IO.FileInfo(sFilename);
System.IO.FileStream fileStream = fileInfo.OpenRead();
PicasaEntry entry = (PicasaEntry)service.Insert(postUri,
fileStream, "image/jpeg", sFilename);
fileStream.Close();
string rtnURL = entry.Media.Content.Url.ToString();
Thanks in advance!
