是否有可能整包，并调用它像整数？ [英] Is it possible to wrap integer and call it like integer?

问题描述

我想在的IDictionary<的INT，INT，驱动程序和GT; 少一点关于它的含义晦涩，所以我想也许包裹这将是一个不错的主意。结果会是这样的的IDictionary< finishPosition，驱动方式>

I want to make the int in IDictionary<int, Driver> a little less obscure about its meaning, so I thought maybe wrapping it would be a good idea. The outcome would be something like IDictionary<finishPosition, Driver>.

最好，finishPosition应该分配这样的 finishPosition = 1 。

Preferably, finishPosition should be assignable like this finishPosition = 1.

我不知道这是可能的，以及如何。

I do not know if this is possible and how.

推荐答案

您可以使用结构与隐式转换。

You could use a struct with an implicit conversion.

public struct FinishPosition {
    public readonly int Position;

    public FinishPosition(int position) {
        this.Position = position;
    }

    public static implicit operator FinishPosition(int position) {
        return new FinishPosition(position);
    }
}


// ...

Dictionary<FinishPosition, Driver> dict = new Dictionary<FinishPosition, Driver>();
Driver bob = new Driver();

// The following two lines are effectively equivalent
dict[new FinishPosition(7)] = bob;
dict[7] = bob;

// So are these two
bob = dict[7];
bob = dict[new FinishPosition(7)]
