Ninject绑定在不同的控制器上

I am trying to Bind two concrete classes to one interface. What command should I use in Ninject to do that? What I am trying to do is to Bind two concrete classes to one interface base on the controller Name. Is that possible? I suppose that in ninject you use the .When to give the conditional but there is no tutorial out there where they show you how to use the .When for ninject.

我试图将两个具体类绑定到一个接口。我应该在Ninject中使用什么命令来做到这一点?我要做的是将两个具体类绑定到控制器名称上的一个接口。那可能吗?我想在ninject中你使用.When来给出条件,但没有教程在那里他们向你展示如何使用.When for ninject。

Here are few examples. Check out Ninject source project and its Tests subproject for various samples of usage, that's the best documentation for it, especially since docs haven't been updated for v2 yet.

这里有几个例子。查看Ninject源项目及其测试子项目的各种使用样本,这是最好的文档,特别是因为尚未针对v2更新文档。

// usage of WhenClassHas attribute
Bind<IRepository>().To<XmlDefaultRepository>().WhenClassHas<PageAttribute>().WithConstructorArgument("contentType", ContentType.Page);
// usage of WhenInjectedInto
Bind<IRepository>().To<XmlDefaultRepository>().WhenInjectedInto(typeof(ServicesController));
Bind<IRepository>().To<XmlDefaultRepository>().WhenInjectedInto(typeof(PageController)).WithConstructorArgument("contentType", ContentType.Page);
Bind<IRepository>().To<XmlDefaultRepository>().WhenInjectedInto(typeof(WidgetZoneController)).WithConstructorArgument("contentType", ContentType.WidgetZone);
// you can also do this
Bind<IRepository>().To<PageRepository>().WhenInjectedInto(typeof(PageController)).WithConstructorArgument("contentType", ContentType.Page);
Bind<IRepository>().To<WidgetZoneRepository>().WhenInjectedInto(typeof(WidgetZoneController)).WithConstructorArgument("contentType", ContentType.WidgetZone);
// or this if you don't need any parameters to your constructor
Bind<IRepository>().To<PageRepository>().WhenInjectedInto(typeof(PageController));
Bind<IRepository>().To<WidgetZoneRepository>().WhenInjectedInto(typeof(WidgetZoneController));
// usage of ToMethod()  
Bind<HttpContextBase>().ToMethod(context => new HttpContextWrapper(HttpContext.Current));
