翻译Ninject到ASP.NET MVC 6 DI [英] Translating Ninject to ASP.NET MVC 6 DI

问题描述

我试图进入新的ASP.NET MVC 6东西，但我有一个非常艰难的时间与他们的新离子系统。我曾尝试在网上找到的资源，但一切我觉得只覆盖绝对是最最低限度使用它。

I am trying to get into the new ASP.NET MVC 6 stuff, but I'm having a very hard time with their new DI system. I have tried to find resources online, but everything I find covers only the absolute most bare minimum to use it.

我是previously使用 Ninject ，和我有几个线的UPS的工作是这样的：

I was previously using Ninject, and I have several wire-ups that work like this:

Bind<IDocumentStore>()
    .ToMethod(c => CreateDocumentStore())
    .InSingletonScope();

private static IDocumentStore CreateDocumentStore() {
    // lots of initialization code, etc.
    return documentStore;
}

但到目前为止，我有困难的时候找到了如何这种行为对微软的新系统的DI翻译的。所有我能找到像这样的例子：

But so far I am having a difficult time finding out how to translate this kind of behaviour to Microsoft's new DI system. All I can find are examples like this:

services.AddTransient<IEmailSender, AuthMessageSender>();
services.AddTransient<ISmsSender, AuthMessageSender>();

和

services.AddMvc();

这里的一切似乎是对目标服务的默认构造函数完全工作。有什么办法来产生，我在这个新的DI系统需要？行为

Where everything seems to work entirely on the default constructor for the target service. Is there any way to produce the behaviour I am needing in this new DI system?

我见过的

services.Configure<TOptions>(options => {});

但我不是是否会做什么，我想，或者如果它被保留用于特定的行为真的很清楚。

But I'm not really clear on whether that will do what I am thinking, or if it is reserved for specific behaviours.

推荐答案

的 AddTransient 方法有不同的重载，其中一个接受一个lambda前pression：

The AddTransient method has various overloads, one of which accepts a lambda expression:

services.AddTransient<IDocumentStore>(s => CreateDocumentStore());

不过看来你是使用Ninject InSingletonScope（） 改良剂所以这可能是比较合适的：

However it seems you are using the Ninject InSingletonScope() modifier so this may be more appropriate:

services.AddSingleton<IEmailSender>(s => CreateDocumentStore());

附加说明：有一些 pre -release文档使用（当然，这是不完整的，可能是不正确的，但可以帮助）

Additional note: There is some pre-release documentation available (of course, it's not complete and may be incorrect but may help)
