Sample usage

Create discogs client

Oauth authentication

  //Create authentication object using private and public keys: you should fournish real keys here
  var oAuthCompleteInformation = new OAuthCompleteInformation("consumerKey", 
                                  "consumerSecret", "token", "tokenSecret");
  //Create discogs client using the authentication
  var discogsClient = new DiscogsClient(oAuthCompleteInformation);

Token based authentication

  //Create authentication based on Discogs token
  var tokenInformation = new TokenAuthenticationInformation("my-token");
  //Create discogs client using the authentication
  var discogsClient = new DiscogsClient(tokenInformation);

Search The DataBase

Using IObservable:

var discogsSearch = new DiscogsSearch()
{
  artist = "Ornette Coleman",
  release_title = "The Shape Of Jazz To Come"
};
//Retrieve observable result from search
var observable = _DiscogsClient.Search(discogsSearch);

Using IEnumerable:

//Alternatively retreive same result as enumerable 
var enumerable = _DiscogsClient.SearchAsEnumerable(discogsSearch);

Get Release, Master, Artist or Label Information

var release = await _DiscogsClient.GetReleaseAsync(1704673);

var master = await _DiscogsClient.GetMasterAsync(47813);

var artist = await _DiscogsClient.GetArtistAsync(224506);

var label = await _DiscogsClient.GetLabelAsync(125);

Download Image

//Retrieve Release information
var res = await _DiscogsClient.GetMasterAsync(47813);
//Download the first image of the release
await _DiscogsClient.SaveImageAsync(res.images[0], Path.GetTempPath(), "Ornette-TSOAJTC");

OAuth: Authorize new user

//Create authentificator information: you should fournish real keys here
var oAuthConsumerInformation = new OAuthConsumerInformation("consumerKey", "consumerSecret");
//Create Authentifier client
var discogsAuthentifierClient = new DiscogsAuthentifierClient(oAuthConsumerInformation);
//Retreive Token and Token secret 
var oauth = discogsClient.Authorize(s => Task.FromResult(GetToken(s))).Result;

Authorize takes a Func< string, Task< string>> as parameter, receiving the authentication url and returning the corresponding access key. Trivial implementation:

private static string GetToken(string url)
{
  Console.WriteLine("Please authorize the application and enter the final key in the console");
  Process.Start(url);
  return Console.ReadLine();
}
