C＃初始化包含動態數組的字典的字典

Question

如您所見，我正在嘗試初始化包含動態數組的字典。 有人可以給我一種更清潔的方法嗎？ 必須有一種使用for循環執行此操作的方法。

// Sizes: 20X, 40X, W, M, WM, Other
sizesDict.Add(eDate, new dynamic[6] { // Date, Size
    new dynamic[6] { // Data
        /* RangeMax */
        new List<decimal> { r.rateEvalDLoc.rateEvalOLoc.charge.Total },
        /* RangeMin */
        new List<decimal> { r.rateEvalDLoc.rateEvalOLoc.charge.Total },
        /* OriginMax */
        new List<string>  { r.rateEvalDLoc.originLoc.LocationName.ToString() },
        /* OriginMin */
        new List<string>  { r.rateEvalDLoc.originLoc.LocationName.ToString() },
        /* DestinationMax */
        new List<string>  { r.destinationLoc.LocationName.ToString() },
        /* DestinationMin */
        new List<string>  { r.destinationLoc.LocationName.ToString() }
    },
    new dynamic[6] { // Data
        /* RangeMax */
        new List<decimal> { r.rateEvalDLoc.rateEvalOLoc.charge.Total },
        /* RangeMin */
        new List<decimal> { r.rateEvalDLoc.rateEvalOLoc.charge.Total },

        new List<string>  { r.destinationLoc.LocationName.ToString() }
    },
    new dynamic[6] { // Data

        new List<string>  { r.rateEvalDLoc.originLoc.LocationName.ToString() },
        /* OriginMin */
        new List<string>  { r.rateEvalDLoc.originLoc.LocationName.ToString() },

        new List<string>  { r.destinationLoc.LocationName.ToString() }
    }

不知道為什么要使用動力學，但是可以這樣做：

創建一個函數以創建最內部的動態數組之一：

private static dynamic[] GetDataArray(
    decimal rangeMax,
    decimal rangeMin,
    string originMax,
    string originMin,
    string destMax,
    string destMin)
{
    return new dynamic[6] { // Data
        /* RangeMax */
        new List<decimal> { rangeMax },
        /* RangeMin */
        new List<decimal> { rangeMin },
        /* OriginMax */
        new List<string>  { originMax },
        /* OriginMin */
        new List<string>  { originMin },
        /* DestinationMax */
        new List<string>  { destMax },
        /* DestinationMin */
        new List<string>  { destMin }
    };
}

然后調用該函數6次，將每個動態數組添加到最外面的動態數組。 最后，將該數組添加到字典中。

dynamic[] allData = new dynamic[6];
for (int i = 0; i < allData.Length; i++)
{
    allData[i] = GetDataArray(
        r.rateEvalDLoc.rateEvalOLoc.charge.Total,
        r.rateEvalDLoc.rateEvalOLoc.charge.Total,
        r.rateEvalDLoc.originLoc.LocationName.ToString(),
        r.rateEvalDLoc.originLoc.LocationName.ToString(),
        r.destinationLoc.LocationName.ToString(),
        r.destinationLoc.LocationName.ToString());
}

sizesDict.Add(eDate, allData);

如果RangeMax始終等於RangeMin，並且OriginMax == OriginMin，並且DestinationMax == DestinationMin，則可以簡化該函數，使其僅具有3個參數。 同樣，如果所有最里面的動態數組都具有相同的內容，則可以進一步簡化它。
