我有一个具有这种设计的WindowsForm项目:
DAL(GenericRepository => UnitOfWork)=> BLL(Service)=> UI
并使用EntityFramWork,Interface,GenericRepository,依赖注入
我在存储库(DAL)中的代码:
public class Repository : RepositoryBase, IDisposable, IRepository where T : class
{
private readonly DbSet dbSet;
private bool disposed = false;
public Repository(GlobalERPEntities dbContext)
{
DBContext = dbContext;
dbSet = DBContext.Set();
}
public virtual IEnumerable GetAll()
{
return dbSet.ToList();
}
}
UnitOfWork(DAL):
public class UnitOfWork : RepositoryBase, IUnitOfWork, IDisposable
{
private Dictionaryobject> repositories;
private bool disposed = false;
public UnitOfWork(GlobalERPEntities dbContext)
{
DBContext = dbContext;
}
public IRepository Repository() where T : class
{
if (repositories == null)
{
repositories = new Dictionaryobject>();
}
if (repositories.Keys.Contains(typeof(T)) == true)
{
return repositories[typeof(T)] as Repository;
}
Repository repo = new Repository(DBContext);
repositories.Add(typeof(T), repo);
return repo;
}
Service(BLL):
public class Service_HR_Person : IService_HR_Person , IDisposable
{
private readonly IUnitOfWork UnitOfWork;
public Service_HR_Person(IUnitOfWork unitOfWork)
{
UnitOfWork = unitOfWork;
}
public virtual IEnumerable GetAll()
{
return UnitOfWork.Repository().GetAll().ToList();
}
MyForm(UI):
using (Service_HR_Person srvPerson = new Service_HR_Person())
{
srvPerson.Delete(base.rowid);
try
{
srvPerson.Save();
MessageManager.Show(Enums.MessageBoxType.InformationTransactionSuccessfully);
}
catch (Exception ex)
{
MessageManager.Show(ErrorManager.ProccessException(ex), Enums.MessageBoxType.Error);
}
}
我不应该在UI层中使用DAL层,并且BLL在DAL和UI之间 但是我在ui中有错误
using (Service_HR_Person srvPerson = new Service_HR_Person())
“ new Service_HR_Person()”说需要在()中使用参数单元作为单位工作量,但我们不应该在UI中使用unitofwork
我阅读了一些使用IOC,ninject,bootstraper和...的文章和示例,但是我无法编写真实的代码
如何使用Ninject或IOC?
请帮我提供代码
谢谢

将新项目添加到名称为“ Configure”的解决方案中
将NuGet中的castle.windsor添加到所有项目中
向该项目添加名称为“ Bootstrapper”的类,并编写此代码
public static WindsorContainer Container = null;
public static void WireUp()
{
Container = new WindsorContainer();
Container.Register(Component.For<GlobalERPEntities>());
Container.Register(Component.For<IUnitOfWork>().ImplementedBy<UnitOfWork>());
Container.Register(Component.For<IService_HR_Person>().ImplementedBy<Service_HR_Person>());
}
并在用户界面中编辑代码
using (Service_HR_Person srvPerson = Bootstrapper.Container.Resolve<Service_HR_Person>())
{
srvPerson.Delete(base.rowid);
try
{
srvPerson.Save();
RemoveRow();
MessageManager.Show(Enums.MessageBoxType.InformationTransactionSuccessfully);
}
catch (Exception ex)
{
MessageManager.Show(ErrorManager.ProccessException(ex), Enums.MessageBoxType.Error);
}
}
此行
using (Service_HR_Person srvPerson = Bootstrapper.Container.Resolve<Service_HR_Person>())
并使用此代码编辑Program.cs
static void Main(string[] argss)
{
Bootstrapper.WireUp();
这是核心工作
