统一容器可以将自身的引用作为构造函数参数传递吗? [英] Can a unity container pass a reference of itself as a constructor parameter?

问题描述

有没有办法让统一容器将自身传递给对象?

Is there a way for a unity container to pass itself to an object?

即:

public class Something {

     public Something(IUnityContainer container) {
           ...
     }
}

推荐答案

简短的回答是肯定的.

当您使用 Resolve 方法时，这应该会自动传递.

This should be passed automatically when you use the Resolve methods.

例如:

IUnityContainer container = new UnityContainer();
var something = container.Resolve<Something>();

此外，如果您想研究它，这与 Prism(在 CodePlex 上)使用的技术相同.

Additionally, this is the same technique that Prism (on CodePlex) uses if you want to look into that.

更新添加的测试:

[TestClass]
public class Spike
{
    [TestMethod]
    public void unityTest()
    {
        var container = new UnityContainer();
        var something= container.Resolve<Something>();
        Assert.AreSame(container, something.Container);
        // This passes. Success.
    }
}

public class Something
{
    public Something(IUnityContainer container)
    {
        Container = container;
    }

    public IUnityContainer Container { get; set; }
}
