MVC3，Ninject和Ninject.MVC3问题 [英] MVC3, Ninject and Ninject.MVC3 problem

问题描述

我刚刚开始使用Ninject与MVC3所以这里是我的问题：
- 我从安装的NuGet 2.2.1.4 Ninject和Ninject.MVC3 2.2.2.0
- 在我的WebUI中（MVC3项目）：

I just start using Ninject with MVC3 so here is my problem: - I installed Ninject 2.2.1.4 and Ninject.MVC3 2.2.2.0 from Nuget - In my WebUI (MVC3 project):

的Global.asax.cs

public class MvcApplication : NinjectHttpApplication
{
    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new HandleErrorAttribute());
    }

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "home", action = "index", id = UrlParameter.Optional } // Parameter defaults
        );

    }

    protected override void OnApplicationStarted()
    {
        base.OnApplicationStarted();

        AreaRegistration.RegisterAllAreas();
        RegisterGlobalFilters(GlobalFilters.Filters);
        RegisterRoutes(RouteTable.Routes);
    }

    protected override IKernel CreateKernel()
    {
        var kernel = new StandardKernel();
        kernel.Load(Assembly.GetExecutingAssembly());
        return kernel;
    }


}

• 在我的域名（类项目），我有我的LINQ to SQL的DataContext，我想从我的web.config加载与连接字符串的背景下，我WebUI中，所以我必须通过构造函数的参数，我也有一些服务，我的域名项目

  • In my Domain (class project), i have my LinQ to SQL datacontext, i want to load the context with the connection string from my Web.Config in my WebUI, so i have to pass the constructor parameter, i also have some services in my Domain project

    public class LotteryDataService
    {
        LinQ.WebDataContext _context;
    
        public LotteryDataService(LinQ.WebDataContext context)
        {
            _context = context;
        }
    
        public IEnumerable<LinQ.LotteryData> Get()
        {
            return _context.LotteryDatas.Take(10);
        }
    }
    

  
  

  如何到DataContext与Ninject与构造函数的参数（这里是连接字符串）？结合

  How to bind the datacontext with Ninject with constructor parameter (here is connection string)?

  推荐答案

  这是你如何通过构造函数的参数。 Ninject将解决指定的构造函数的参数相匹配的构造函数。

  This is how you pass a constructor parameter. Ninject will resolve the constructor that matches the specified constructor arguments.

  public class DataModule : NinjectModule
  {
      public override void Load()
      {
          string connectionString = "...";
          Bind<WebDataContext>().ToSelf()
              .WithConstructorArgument("connection", connectionString);
      }
  }
  

  的第一个参数 .WithConstructorArgument（）应该是构造函数参数的名称。这是 fileOrServerOrConnection 基类，但连接在派生类中。

  The first argument to .WithConstructorArgument() should be the name of the constructor parameter. This is fileOrServerOrConnection in the base class, but connection in derived class.
