我在mvc项目中实现工作单元模式,

public class UnitOfWork : IUnitOfWork
{
    private TransactionScope _transaction;
    private readonly BodoShopEntities _db;

    public UnitOfWork()
    {
        _db = new BodoShopEntities();
    }

    public void Dispose()
    {
        if (_db != null)
        {
            _db.Dispose();
        }
        System.GC.SuppressFinalize(this);
    }

    public void StartTransaction()
    {
        _transaction = new TransactionScope();
    }

    public void Commit()
    {
        _db.SaveChanges();
        _transaction.Complete();
    }

    public DbContext Db
    {
        get { return _db; }
    }
}

还有存储库模式,

public partial interface IRepository<T> where T : class
{
    T GetById(object id);
    void Insert(T entity);
    void Update(T entity);
    void Delete(T entity);
    IQueryable<T> Table { get; }
    T Single(object primaryKey);
    T SingleOrDefault(object primaryKey);
    bool Exists(object primaryKey);
    IUnitOfWork UnitOfWork { get; }
}

在Ninject中我使用InThreadScope作为工作单元,它是否正确?

private static void RegisterServices(IKernel kernel)
{
        kernel.Bind(typeof(IUnitOfWork)).To(typeof(UnitOfWork)).InThreadScope();
}

对于Web应用程序,请使用InRequestScope()。不要忘记同时注册OnePerRequestModule,因此UnitOfWork / db上下文将在请求结束时处理。


InRequestScope()扩展程序目前位于Ninject.Web.Common
