C#数组详解

数组分为：普通数组，多维数组、锯齿数组和自己创建的数组；具体使用如下

 /// <summary>
        /// 普通数组
        /// </summary>
        /// <returns></returns>
        public string[] GetStringList()
        {
            string[] strArray = new string[2] { "1", "2" };
            return strArray;
        }
        /// <summary>
        /// 多维数组
        /// </summary>
        /// <returns></returns>
        public string[,] GetStringMoreList()
        {
            string[,] strArr = new string[2, 2];
            strArr[0, 0] = "1";
            strArr[0, 1] = "2";
            strArr[1, 0] = "3";
            strArr[1, 1] = "4";
            return strArr;
        }
        /// <summary>
        /// 锯齿数组
        /// </summary>
        /// <returns></returns>
        public void GetStringLenMoreList()
        {
            string[][] strArrs = new string[3][];
            strArrs[0] = new string[2] { "1", "2" };
            strArrs[1] = new string[4] { "1", "2", "3", "4" };
            strArrs[2] = new string[3] { "1", "2", "3" };
            for (int i = 0; i < strArrs.Length; i++)
            {
                for (int j = 0; j < strArrs[i].Length; j++)
                {
                    Console.WriteLine($"行：{i}，列：{j}，值：{strArrs[i][j]}");
                }
            }
        }
        /// <summary>
        /// 创建数组
        /// </summary>
        public void CreateArray()
        {
            Array intArr = Array.CreateInstance(typeof(int), 5);
            for (int i = 0; i < 5; i++)
            {
                intArr.SetValue(new Random().Next(10), i);
            }
            for (int i = 0; i < intArr.Length; i++)
            {
                Console.WriteLine(intArr.GetValue(i));
            }
            //版本重载
            int[] lengths = { 2, 3 };
            int[] lowerBounds = { 1, 10 };
            Array racers = Array.CreateInstance(typeof(Person), lengths, lowerBounds);
            racers.SetValue(new Person { FirstName = "Alain", LastName = "Prost10" }, 1, 10);

            Console.WriteLine(((Person)racers.GetValue(1, 12)).LastName);
        }
