c# - 如何优化并使其更具可读性

Question

大家好，我有一个关于如何使它更干净、可重用和可读的问题。我有一些数据模型(遗物)，这具有稀有性和水平。根据级别和稀有性，必须对其进行分组，以便稍后将其应用于某些数学计算。出于这个原因，我需要解析我所有的遗物并检查等级和稀有度并存储在一个 var 计数器中。

public double TotalGlobalBonus
{
    get
    {
        float commonRarityMultiplier = 20;
        float rareRarityMultiplier = 120;
        float epicRarityMultiplier = 320;
        float legendaryRarityMultiplier = 540;

        int rarityCommonLevel1 = 0;
        int rarityCommonLevel2 = 0;
        int rarityCommonLevel3 = 0;
        int rarityCommonLevel4 = 0;
        int rarityCommonLevel5 = 0;

        int rarityRareLevel1 = 0;
        int rarityRareLevel2 = 0;
        int rarityRareLevel3 = 0;
        int rarityRareLevel4 = 0;
        int rarityRareLevel5 = 0;

        int rarityEpicLevel1 = 0;
        int rarityEpicLevel2 = 0;
        int rarityEpicLevel3 = 0;
        int rarityEpicLevel4 = 0;
        int rarityEpicLevel5 = 0;

        int rarityLegendaryLevel1 = 0;
        int rarityLegendaryLevel2 = 0;
        int rarityLegendaryLevel3 = 0;
        int rarityLegendaryLevel4 = 0;
        int rarityLegendaryLevel5 = 0;

        double rare = (rareRarityMultiplier / 100) * (rarityRareLevel1 * 1 + rarityRareLevel2 * 5 +

                                                        rarityRareLevel5 * 40);
        double epic = (epicRarityMultiplier / 100) * (rarityEpicLevel1 * 1 + rarityEpicLevel2 * 5 +
                                                      rarityEpicLevel3 * 10 + rarityEpicLevel4 * 20 +
                                                      rarityEpicLevel5 * 40);
        double legendary = (legendaryRarityMultiplier / 100) * (rarityLegendaryLevel1 * 1 + rarityLegendaryLevel2 * 5 +
                                                                rarityLegendaryLevel3 * 10 + rarityLegendaryLevel4 * 20 +
                                                                rarityLegendaryLevel5 * 40);

        double final = common + rare + epic + legendary;

        return final;
    }
}

这是一个非常长的属性，并且会随着层数的增加而增长，所以这不是精确可扩展的

您需要将所有这些值放在 Dictionary 中具有 RarityType 类型的键和 int[] 类型的值。

var rarity = new Dictionary<RarityType, int[]>();
rarity[RarityType.COMMON] = new int[6];
rarity[RarityType.RARE] = new int[6];
rarity[RarityType.EPIC] = new int[6];
rarity[RarityType.LEGENDARY] = new int[6];

foreach (RelicModel relic in this.equipedRelics)
{
    rarity[relic.rarity][relic.Level]++;
}

每个数组的第一个元素，即索引 = 0 的元素，将不被使用。
