Question

I hope I can explain my problem in a way that it s clear for everyone. We need your suggestions on this.

We have an Enum Type which has more than 15 constants defined. We receive a report from a web service and translate its one column into this Enum type. And based on what we receive from that web service, we run specific functions using Dictionary

Why am I asking for ideas? Let s say 3 of these Enum contants meet specific functions in our Dictionary but the rest use the same function. So, is there a way to add them into our Dictionary in a better way rather than adding them one by one? I also want to keep this structure because when it s time, we might have specific functions in the future for the ones that I described as "the rest".

在这里更清楚的是,我们又努力做到:

Enum:

public enum Reason{
    ReasonA,
    ReasonB,
    ReasonC,
    ReasonD,
    ReasonE,
    ReasonF,
    ReasonG,
    ReasonH,
    ReasonI,
    ReasonJ,
    ReasonK
}

界定我们的理论:

public Dictionary<Reason, Action<CustomClassObj, string>> ReasonHandlers = new Dictionary<Reason, Action<CustomClassObj, string>>{
    { Reason.ReasonA, HandleReasonA },
    { Reason.ReasonB, HandleReasonB },
    { Reason.ReasonC, HandleReasonC },
    { Reason.ReasonD, HandleReasonGeneral },
    { Reason.ReasonE, HandleReasonGeneral },
    { Reason.ReasonF, HandleReasonGeneral },
    { Reason.ReasonG, HandleReasonGeneral },
    { Reason.ReasonH, HandleReasonGeneral },
    { Reason.ReasonI, HandleReasonGeneral },
    { Reason.ReasonJ, HandleReasonGeneral },
    { Reason.ReasonK, HandleReasonGeneral }
};

因此,基本上我所说的话是,是否有办法添加Reason, Function pair more intelligently? 因为正如你在理赔之后可以看到的那样,所有其他理由都使用同样的功能。

感谢你的建议。

你可以尝试像这样的东西,只把习俗理智手放在独裁者身上,然后回到将军身上。

public Dictionary<Reason, Action<CustomClassObj, string>> ReasonHandlers = new Dictionary<Reason, Action<CustomClassObj, string>>{
    { Reason.ReasonA, HandleReasonA },
    { Reason.ReasonB, HandleReasonB },
    { Reason.ReasonC, HandleReasonC }};


public Action<CustomClassObj, string> ReasonHandlerLookup (Reason reason) {
    Action<CustomClassObj, string> result = null;
    ReasonHandlers.TryGetValue(reason, out result);
    return result ?? HandleReasonGeneral;
}
