第十九节 数组二

二维数组

int[,] Matrix = {{1,2,3},{4,,5,6},{7,8,9}};

C#中的索引是从0开始计算，因此它的第一个元素是Matrix[0,0]

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ErWei
{
    class Program
    {
        static void Main(string[] args)
        {
            int[,] Max = new int[3,3] { {1,2,3},{4,5,6},{7,8,9}};
            int sum = 0;
            foreach (int number in Max)
            {
                Console.WriteLine(number);
                sum += number;
             
            }
            Console.WriteLine(sum);
        }
    }
}

　　可变数组

int[][] jaggageArray = new int [2][]{new int[3]{1,2,3},new int[4]{1,2,3,4}};

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace KeBian
{
    class Program
    {
        static void Main(string[] args)
        {
            int[][] Kb = new int[2][] {new int[3]{1,2,3},new int[4]{1,2,3,4} };
            foreach(int[] line in Kb)
            {
                foreach (int elment in line)
                {
                    Console.Write(elment);
                    Console.Write("\n");
                }
            }
        }
    }
}
