数组

Array

一维数组

int[] arr = new int[] {1,2,3};int[] arr = {1,2,3};

二维数组

int[,] arr2 = new int[2,3];int[,] arr2 = new int[,] {{1,2,3},{4,5,6}};

不规则数组（数组的数组）

int[][] j2;int[][] j2 = new int[3][];j2[0] = new int [] {1,2,3};j2[1] = new int [] {1,2,3,4};j2[2] = new int [] {1,2,3,4,5,6};

ArrayList

容量可变数组，只能是一维数组

using System.Collections;ArrayList arr = new ArrayList();string str1;arr.Add(str1);for(int i = 0; i<arr.Count; i++)Console.WriteLine(arr[i]);
