.net ASCII 排序一般做为接口 排序用的

    public static Dictionary AsciiDictionary(Dictionary sArray)
    {
        Dictionary asciiDic = new Dictionary();
        string[] arrKeys = sArray.Keys.ToArray();
        Array.Sort(arrKeys, string.CompareOrdinal);
        foreach (var key in arrKeys)
        {
            string value = sArray[key];
            asciiDic.Add(key, value);
        }
        return asciiDic;
    }
