团结 - ResolveAll与条件名称 [英] Unity - ResolveAll by name with condition

问题描述

我不知道是否有可能通过在他们被注册的名称一些条件来解决统一所有的依赖关系。

I was wondering if it is possible to resolve all dependancies in Unity by some condition on the name that they were registered.

例如：
Resloving注册的所有接口所在的名字注册了ProcessA启动。

For example: Resloving all interfaces registered where the name registered starts with "ProcessA".

和如果没有办法做到这一点，那么也许我可以如何扩展统一，让这一点。

And if there is no way to do this then perhaps how can i extend Unity to allow this.

推荐答案

您应该能够使用注册来做到这一点，我会建议扩展方法而不是扩展统一直接：

You should be able to use Registrations to do this and I would recommend an extension method rather than extending Unity directly:

var matches = c.Resolve<IMyService>(name => name.StartsWith("ProcessA"));

使用这个扩展方法：

Using this extension method:

public static class MyUnityExtensions
{
    public static IEnumerable<T> Resolve<T>(this IUnityContainer c, Func<string, bool> match)
    {
        var matches = c.Registrations.Where(r => match(r.Name));

        foreach (var registration in matches)
        {
            yield return c.Resolve<T>(registration.Name);
        }
    }

}
