无聊在写一个插入排序

        public static int[] crSort(int[] arrayInt)
        {
            if (arrayInt.Length < 2)
            {
                return arrayInt;
            }
            for (int i = 0; i < arrayInt.Length - 1; i++)
            {
                var value = arrayInt[i];
                for (var j = i + 1; j < arrayInt.Length; j++)
                {
                    if (value > arrayInt[j])
                    {
                        var tempValue = arrayInt[j];
                        arrayInt[j] = value;
                        value = tempValue;
                    }
                }
            }
            return arrayInt;
        }
