Get artist albums by mbid

This can be done using a browse request:

private static async Task BrowseReleaseGroups()
{
    // Britney Spears
    var arid = "45a663b5-b1cb-4a91-bff6-2bef7bbfdd76";

    int limit = 50;

    var groups = await ReleaseGroup.BrowseAsync("artist", arid, limit, 0, "ratings");

    Console.WriteLine("Album");
    Console.WriteLine();

    foreach (var item in groups.Items.Where(g => IsOffical(g)).OrderBy(g => g.FirstReleaseDate))
    {
        Console.WriteLine("     {0} - {1}  {2}  {3}", item.FirstReleaseDate.ToShortDate(),
            item.Id, GetRating(item.Rating, 10), item.Title);
    }

    Console.WriteLine();
    Console.WriteLine("Album + Compilation");
    Console.WriteLine();

    foreach (var item in groups.Items.Where(g => IsCompilation(g)).OrderBy(g => g.FirstReleaseDate))
    {
        Console.WriteLine("     {0} - {1}  {2}  {3}", item.FirstReleaseDate.ToShortDate(),
            item.Id, GetRating(item.Rating, 10), item.Title);
    }

    Console.WriteLine();

    if (groups.Items.Count == limit)
    {
        Console.WriteLine("There are probably more items to browse ...");
    }
}

static bool IsOffical(ReleaseGroup g)
{
    return g.PrimaryType.Equals("album", StringComparison.OrdinalIgnoreCase)
        && g.SecondaryTypes.Count == 0
        && !string.IsNullOrEmpty(g.FirstReleaseDate);
}

static bool IsCompilation(ReleaseGroup g)
{
    return g.PrimaryType.Equals("album", StringComparison.OrdinalIgnoreCase)
        && g.SecondaryTypes.Count > 0
        && g.SecondaryTypes.Contains("Compilation")
        && !string.IsNullOrEmpty(g.FirstReleaseDate);
}

static string GetRating(Rating rating, int length)
{
    string s = "";

    if (!rating.Value.HasValue)
    {
        return s.PadRight(length);
    }

    int stars = (int)(length * (double)rating.Value / 5.0);

    s = s.PadRight(stars, '+');

    return s.PadRight(length, '-');
}

Awesome! This is helpful!
Pity it wont include some sort of popularity factor for each album.

[wo80]

Sure you can!

var groups = await ReleaseGroup.BrowseAsync("artist", arid, limit, 0, "ratings");

I've updated the code above to show the rating.

[ColorTwist]

I tried that, the function returns 'null' :(

[wo80]

EDIT: Sorry, this is a change, I haven't committed yet. In Rating.cs, change

public double Value { get; set; }

to

public double? Value { get; set; }

Please leave this issue open, until it's fixed.

---

The updated code example works well for me. Since the rating value returned by the webservice might be null, the C# equivalent rating.Value is a nullable type (meaning, you have to check, if the value is present).

[ColorTwist]

Sure, i also Verified that nullable type operates correctly.

[ColorTwist]

Verified, fixed that Rating value can be nullable.
