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]);
