【c#】c#中 数组 的基本操作

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;
//数组的使用 namespace unit5 {     class Program     {         static void Main(string[] args)         {             //数组的声明             //int[] myIntArray;             //int [ , ] myIntArray; //二维数组             //int [][] myIntArray;  //数组的数组
            //一维数组两种初始化方式             //1. int [] myIntArray = {2, 4, 5, 1, 8};             //2. int [] myIntArray = new int[5];     //默认值为0
            //二维数组初始化             //int[,] myIntArray = { { 1, 3, 4 }, { 2, 3, 4 } };  //两行三列
            //数组的数组初始化             //1.             //int [][] myIntArray = new int [2][];             //myIntArray[0] = new int[3];             //myIntArray[1] = new int[4];             //2.             //int[][] myIntArray = new int[2][] { new int [3]{ 1, 2, 3 }, new int [4]{ 1, 2, 4, 5 } };             //简化为             //int[][] myIntArray = { new int[]{1, 2, 4},             //                       new int[]{2, 3, 4, 6, 7},             //                       new int[]{1, 4}};
            //组合这两种方式             //int[] myIntArray = new int[5] { 2, 4, 5, 1, 8 };             //注意：这种方式，初始化的元素个数必须与数组大小相匹配
            //访问数组             //string[] myStringArray = {"hello1", "hello2", "hello3"};
            //用for 可以读写数组             //for (int i = 0; i < myStringArray.Length; i++)             //{             //    Console.WriteLine(myStringArray[i]);             //}
            //用 foreach 只读数组，不可修改             //foreach (string stringArray in myStringArray)             //{             //    Console.WriteLine(stringArray);             //}
            //Console.ReadKey();         }     } }
