How to List Today's Horse Races

var credentials = new Credentials("USERNAME", "PASSWORD", "APP_KEY");

using var client = new BetfairApiClient(credentials);

var filter = new ApiMarketFilter()
    .WithMarketTypes(MarketType.Win)
    .WithCountries(Country.UnitedKingdom, Country.Ireland)
    .WithEventTypes(EventType.HorseRacing)
    .FromMarketStart(DateTimeOffset.UtcNow)
    .ToMarketStart(DateTimeOffset.UtcNow.AddDays(1));

var query = new MarketCatalogueQuery()
    .Include(MarketProjection.Event)
    .Include(MarketProjection.MarketStartTime)
    .Include(MarketProjection.MarketDescription)
    .Include(MarketProjection.RunnerDescription)
    .OrderBy(MarketSort.FirstToStart)
    .Take(200);

var marketCatalogues = await client.MarketCatalogue(filter, query);

Or use the helper extension.

var filter = new ApiMarketFilter()
    .TodaysCard();

var query = new MarketCatalogueQuery()
    .Include(MarketProjection.Event)
    .Include(MarketProjection.MarketStartTime)
    .Include(MarketProjection.MarketDescription)
    .Include(MarketProjection.RunnerDescription)
    .OrderBy(MarketSort.FirstToStart)
    .Take(200);

var marketCatalogues = await client.MarketCatalogue(filter, query);
