是否有可能实现在C＃中混入？ [英] Is it possible to implement mixins in C#?

问题描述

我听说它可能带扩展方法，但我不能完全弄清楚自己。我想看看是否有可能一个具体的例子。

I've heard that it's possible with extension methods, but I can't quite figure it out myself. I'd like to see a specific example if possible.

谢谢！

推荐答案

这真的取决于你的意思是混入是什么 - 大家似乎有一个稍微不同的想法。那种混入的我的如的看到（但不是在C＃中可用）正在实现通成分简单的：

It really depends on what you mean by "mixin" - everyone seems to have a slightly different idea. The kind of mixin I'd like to see (but which isn't available in C#) is making implementation-through-composition simple:

public class Mixin : ISomeInterface
{
    private SomeImplementation impl implements ISomeInterface;

    public void OneMethod()
    {
        // Specialise just this method
    }
}

，编译器将实现ISomeInterface只是进行代理每一个成员，除非是班上另一个实现implement执行直接。

The compiler would implement ISomeInterface just by proxying every member to "impl" unless there was another implementation in the class directly.

这一切都不是可能的此刻虽然：）

None of this is possible at the moment though :)
