Repository

用來處理資料庫內某 model 的資料查詢、更新、新增、刪除。

  • IQueryRepository<TEntity>:用於唯讀的查詢,可直接從 IUnitOfWorkQueryRepository<TEntity>() 的方法中取得某 model 的 IQueryRepository 物件。

/* IQueryRepository<TEntity> 介面 */

public interface IQueryRepository<TEntity> : IDisposable where TEntity : class
{
	/// <summary>
	/// 取得某一筆資料
	/// </summary>
	/// <param name="predicate">The predicate.</param>
	/// <returns></returns>
	TEntity Get(Expression<Func<TEntity, bool>> predicate);

	/// <summary>
	/// 取得全部資料來做查詢
	/// </summary>
	/// <returns></returns>
	IQueryable<TEntity> GetAll();
}

  • IRepository<TEntity>:除了查詢外,可以做到 model 的更新、新增及刪除,必須自定義處理 model 的類別以供其他程式呼叫。

/* IRepository<TEntity> 介面 */
public interface IRepository<TEntity> : IQueryRepository<TEntity> where TEntity : class
{
	TEntity Create(TEntity instance);

	/// <summary>
	/// 依照  PrimaryKey 更新欄位
	/// </summary>
	/// <typeparam name="TProperty">The type of the property.</typeparam>
	/// <param name="keyValues">The key values.</param>
	/// <param name="property">The property.</param>
	/// <param name="value">The value.</param>
	void Update<TProperty>(object[] keyValues, Expression<Func<TEntity, TProperty>> property, TProperty value);

	/// <summary>
	/// 依MODEL的值更新
	/// </summary>
	/// <param name="instance">The instance.</param>
	/// <param name="keyValues"></param>
	void Update(TEntity instance, params object[] keyValues);


	/// <summary>
	/// Deletes the specified instance.
	/// </summary>
	/// <param name="instance">The instance.</param>
	/// <param name="keyValues">The key values.</param>
	/// <returns></returns>
	void Delete(TEntity instance, params object[] keyValues);
}

  • GenericRepository<TEntity>:此類別實作 IRepository<TEntity> 的基本增改刪功能,供其他自定 Repository 繼承。

如想要變更 Budget 這個 model,需宣告 IBudgetRepository 這個介面,並繼承 IRepository<Budget>。及宣告 BudgetRepository 並繼承GenericRepository<Budget>,並實作。


public interface IBudgetRepository : IRepository<Budget>
{

}

public class BudgetRepository : GenericRepository<Budget>, IBudgetRepository
{
	public BudgetRepository(IToolMngFactory factory) : base(factory)
	{
	}
}

UnitOfWork

UnitOfWork 內為處理 DB 資料的實體及其 factory

  • IUnitOfWork:用來處理取得 Repository 或 QueryRepository、Save Changes、Begin Transaction 行為。
  • IUnitOfWorkFactory:用來產生 IUnitOfWork 實體的工廠介面。
