A basic score-keeping service for games with endpoints for adding, viewing, and deleting scores.

A score-keeping service for games written as an ASP.NET Core Web API, with endpoints for adding, retrieving, and deleting scores.

This project uses a custom abstraction mechanism to simplify access to a MySQL database. To access a database, an interface can be created, and the methods can be annotated with the SqlQuery or SqlUpdate attributes to specify the SQL commands they should execute. The method parameters are automatically mapped to query parameters, and query results are automatically mapped to return values.

Example:

public class HighScore
{
    public string name;
    public int score;
}

public interface HighScoreService
{
    [SqlQuery("select `name`, `score` from `scores` where `game`=@game order by `score` desc limit @max")]
    List<HighScore> GetScores(string game, int max);
}

// `ProxyFactory` generates an implementation of `HighScoreService` at runtime
// which forwards all method calls to `SqlProxyTarget`, which executes the
// appropriate SQL commands based on the `SqlQuery` or `SqlUpdate` attributes
// attached to each interface method.

var proxyTarget = new SqlProxyTarget("MySQL connection string");
var highScoreService = ProxyFactory.Create<HighScoreService>(proxyTarget);
List<HighScore> scores = highScoreService.GetScores("my game", 100);
PrintAllScores(scores);
