我已經(jīng)使用存儲(chǔ)庫(kù)模式創(chuàng)建了我的數(shù)據(jù)提供程序。首先，我設(shè)計(jì)了一個(gè)基礎(chǔ)存儲(chǔ)庫(kù)接口，如下所示：internal interface IGenericRepository<T, in TResourceIdentifier>{    Task<IEnumerable<T>> GetManyAsync();    Task<T> GetAsync(TResourceIdentifier id);    Task PutAsync(T model);    Task<T> PostAsync(T model);    Task DeleteAsync(TResourceIdentifier id);}然后我實(shí)現(xiàn)了它：public class GenericRepository<T, TResourceIdentifier> : IDisposable, IGenericRepository<T, TResourceIdentifier>     where T : class{    private bool _disposed;    protected HttpClientHelper<T, TResourceIdentifier> Client;    protected GenericRepository(string addressSuffix)    {        Client = new HttpClientHelper<T, TResourceIdentifier>(Properties.Settings.Url, addressSuffix);    }    public async Task<IEnumerable<T>> GetManyAsync()    {        return await Client.GetManyAsync();    }    // All other CRUD methods and dispose    public void Dispose()    {        Dispose(true);        GC.SuppressFinalize(this);    }    private void Dispose(bool disposing)    {        if(_disposed || !disposing) return;        if(Client != null)        {            var mc = Client;            Client = null;            mc.Dispose();        }        _disposed = true;    }}然后我為每個(gè)實(shí)體創(chuàng)建了自定義存儲(chǔ)庫(kù)接口。例如：internal interface IOrderRepository : IGenericRepository<Order, int>{    Task<IEnumerable<Order>> GetOrderBySomeConditionAsync(string condition );}最后，我實(shí)現(xiàn)了自定義存儲(chǔ)庫(kù)：public class OrderRepository : GenericRepository<Order, int>, IOrderRepository{    public OrderRepository(string addressSuffix) : base(addressSuffix)    {    }    public async Task<IEnumerable<Order>> GetOrderBySomeConditionAsync(string condition)    {        //get all the orders (GetManyAsync()) and then returns the ones meeting the condition    }}請(qǐng)注意，HttpClientHelper使用HttpClient，需要手動(dòng)處置。我創(chuàng)建了一個(gè) MVC Web 應(yīng)用程序，并在類(lèi)級(jí)別定義了存儲(chǔ)庫(kù)，如下所示：IOrderRepository _orderRepository = new OrderRepository();這會(huì)影響 Dispose，但卻是反模式。我在實(shí)現(xiàn)中缺少什么，即每次調(diào)用時(shí)都沒(méi)有釋放該實(shí)例？
