Ninject 在 Winform、 Asp.net MVC中连络EntityFramework的应用

Ninject 在 Winform、 Asp.net MVC中连络EntityFramework的应用( 注入同一个DbContext的应用名人名言:科学是老老实实的东西,它要靠许许多多人民的劳动和智慧积累起来。——李四光 

Ninject 在 Winform、 Asp.net MVC 中连络EntityFramework的应用( 注入同一个DbContext的应用办法)


Demo顶用到了 RepositoryT.dll, RepositoryT.EntityFramework.dll,Ninject.dll,Ninject.Web.MVC.dll, Ninject.Web.Common.dll


 


应用到的自定义类:


//营业相干的类


DataAccessRepository.cs


IDataAccessRepository.cs


//Ninject相干的类


DataAccessNinjectModule.cs


DataAccessKernelBase.cs


 


具体内容:


//营业相干的类


 


IDataAccessRepository.cs



using RepositoryT.Infrastructure;

using System;
using System.Collections.Generic;
using System.Data.Entity.Infrastructure;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace DataAccess
{
public interface IDataAccessRepository<TEntity> : IRepository<TEntity> where TEntity : class
{
DbEntityEntry GetDbEntityEntry(TEntity entity);
}
}

 


DataAccessRepository.cs



using RepositoryT.EntityFramework;

using RepositoryT.Infrastructure;
using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Data.Entity.Infrastructure;
using System.Linq;
using System.Linq.Expressions;
using System.Text;
using System.Threading.Tasks;

namespace DataAccess
{
public class DataAccessRepository<T, TContext> : RepositoryBase<TContext>, IDataAccessRepository<T>
where T : class
where TContext : class, IDbContext, IDisposable
{

private readonly IDbSet<T> _dbset;
public DataAccessRepository(IDataContextFactory<TContext> databaseFactory) :
base(databaseFactory)
{
_dbset = DataContext.Set<T>();
}

public virtual void Add(T entity)
{
_dbset.Add(entity);
}
    

        public DbEntityEntry GetDbEntityEntry(T entity)
        {
            return DataContext.Entry(entity);
        }
}
}

 


//Ninject相干的类


DataAccessNinjectModule.cs



using System;

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Ninject.Modules;
using DataEntities;
using Ninject.Activation;
using Ninject;
using RepositoryT.EntityFramework;
using RepositoryT.Infrastructure;

namespace DataAccess
{
public class DataAccessNinjectModule : NinjectModule
{
public override void Load()
{
var testNinjectEntities = new TestNinjectEntities();
//Kernel.Bind<ILoginRepository>()
// .To<LoginRepository>();

var factory = new DefaultDataContextFactory<TestNinjectEntities>();

Kernel.Bind<IDataAccessRepository<Login>>()
.To<DataAccessRepository<Login, TestNinjectEntities>>()
.InSingletonScope()
.WithConstructorArgument("databaseFactory",
factory);

Kernel.Bind<IUnitOfWork>()
.To<UnitOfWork<TestNinjectEntities>>()
.InSingletonScope()
.WithConstructorArgument("databaseFactory",
factory);

}
}
}

 


DataAccessKernelBase.cs


 


 


//Winform 调用


Program.cs



namespace WindowsFormsApplication

{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);


var kernel = new StandardKernel(new DataAccessNinjectModule());

var form = kernel.Get<Form1>();

Application.Run(form);
}
}
}

Form1 .cs



using DataAccess;

using DataEntities;
using RepositoryT.Infrastructure;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WindowsFormsApplication
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

IDataAccessRepository<Login> _DataAccessRepository;
IUnitOfWork _UnitOfWork;

public Form1(IDataAccessRepository<Login> dataAccessRepository,
IUnitOfWork unitOfWork)
{
_DataAccessRepository = dataAccessRepository;
_UnitOfWork = unitOfWork;


if (_DataAccessRepository != null &&
_UnitOfWork != null)
{
var b = true;
try
{
_DataAccessRepository.Add(new DataEntities.Login()
{
UserName = "Admin",
Password = "123",
});

_UnitOfWork.Commit();
}
catch (Exception)
{
b = false;
}
}
}
}
}

 


ASP.NET MVC中应用:



    [Authorize]

public class AccountController : Controller
{

IDataAccessRepository<Login> _LoginDataAccessRepository;
IUnitOfWork _UnitOfWork;

public AccountController(IDataAccessRepository<Login> loginDataAccessRepository,
IUnitOfWork unitOfWork)
{
_LoginDataAccessRepository = loginDataAccessRepository;
_UnitOfWork = unitOfWork;
}
     public ActionResult Save(LoginModel model, string returnUrl)
        {
            var b = true;
            try
            {
                _LoginDataAccessRepository.Add(new DataEntities.Login()
                {
                    UserName = model.UserName,
                    Password = model.Password,
                });

                _UnitOfWork.Commit();

                
            }
            catch (Exception)
            {
                b = false;
            }
           
            if (b)
            {
                return RedirectToLocal("http://www.ideaam.com");
            }

            // If we got this far, something failed, redisplay form
            ModelState.AddModelError("", "The user name or password provided is incorrect.");
            return View(model);
        }
}
