Ninject:将某些东西绑定到自身是什么意思? [英] Ninject: What does it mean to bind something to itself?

问题描述

Ninject具有self binding的功能，例如Bind<Samurai>().ToSelf();

Ninject has the functionality of self binding like Bind<Samurai>().ToSelf();

我读到了有关此内容的信息，但我没有得到任何重视或如何发挥作用.任何评论表示赞赏.

I read about this but I don't get the importance or how this can be useful. Any comments are appreciated.

推荐答案

如果Ninject找到需要创建的对象，并且它的构造函数带有Samurai参数，则它不知道如何实例化它.

If Ninject finds a object that needs to be created and it has a constructor that has a Samurai parameter it does not know how to instantiate it.

但是当您使用Bind<Samurai>().ToSelf();时，Ninject知道需要创建一个Samurai才能传递给Samurai参数.

But when you use Bind<Samurai>().ToSelf(); then Ninject knows that a Samurai needs to be created to pass to the Samurai parameter.

如果没有该绑定，则ninject不知道要传递什么，例如，可能存在SamuraiSubClass类型.但是通过明确地说，当Ninject找到需要为其创建Samurai的Samurai参数时，Ninject确切地知道该怎么做.

If that binding was not there then ninject didn't know what to pass, for example there might have been a SamuraiSubClass type. But by explicitly saying that when Ninject finds a Samurai parameter that it needs to create a Samurai for that parameter then Ninject knows exactly what to do.
