.NET bindings for libdiscid using P/Invoke

.NET bindings for MusicBrainz libdiscid

About

dotnet-discid provides .NET bindings for the MusicBrainz DiscID library libdiscid. It allows calculating DiscIDs (MusicBrainz and freedb) for Audio CDs. Additionally the library can extract the MCN/UPC/EAN and the ISRCs from disc.

Requirements

• .NET or Mono
• libdiscid >= 0.1.0

To utilize all features you will need libdiscid 0.5.0 or later. The libdiscid feature matrix shows which features are available in each version.

Installation

If you are using Visual Studio the easiest way to install and use dotnet-discid is by installing the NuGet package from https://nuget.org/packages/DotNetDiscId/ . The package contains the .NET assembly and the corresponding native DLLs (both 32 and 64 bit). You just have to make sure to set your build configuration to either x86 or x64 instead of AnyCPU.

If you compile the DotNetDiscId.dll yourself and use it in a project make sure you also have the native libdiscid libraries available. Pre-compiled versions of libdiscid for Windows can be downloaded from http://musicbrainz.org/doc/libdiscid . On Windows it is recommended to ship the discid.dll in your project. If you are using Mono on other platforms such as Linux or OSX you can use a system wide installation of libdiscid, e.g. installed using the platform's package manager.

Source and binary releases of dotnet-discid are available at: http://users.musicbrainz.org/~outsidecontext/dotnet-discid/

Usage

In order to use dotnet-discid you have to reference the DotNetDiscId.dll assembly in your project and make sure the native discid library is available (see notes above).

Below is a simple usage example. The dotnet-discid-example project provides a more complete example.

try
{ 
    string device = DiscId.Disc.DefaultDevice;
    using (var disc = DiscId.Disc.Read(device, Features.Mcn | Features.Isrc))
    {
        Console.Out.WriteLine("DiscId         : {0}", disc.Id);
        Console.Out.WriteLine("FreeDB ID      : {0}", disc.FreedbId);
        Console.Out.WriteLine("MCN            : {0}", disc.Mcn);
        Console.Out.WriteLine("First track no.: {0}", disc.FirstTrackNumber);
        Console.Out.WriteLine("Last track no. : {0}", disc.LastTrackNumber);
        Console.Out.WriteLine("Sectors        : {0}", disc.Sectors);
        Console.Out.WriteLine("Submission URL : {0}", disc.SubmissionUrl);
    }
}
catch (DiscIdException ex)
{
    Console.Out.WriteLine("Could not read disc: {0}.", ex.Message);
}
