二维数组、齿形数组和游长变元表_.NET_编程开发_程序员俱乐部

实例学习，代码如下：

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

namespace TwoDimensionArray
{
    class Program
    {
        public static void OutputArray(int[,] array)
        {
            for (int i = 0; i < array.GetLength(0); i++)
            {
                for (int j = 0; j < array.GetLength(1); j++)
                {
                    Console.Write("{0}", array[i, j]);
                }
                Console.WriteLine();
            }
            Console.WriteLine();
        }

        public static void OutputJaggedArray(int[][] array)
        {
            foreach (var row in array)
            {
                foreach (var element in row)
                {
                    Console.Write("{0}", element);
                }
                Console.WriteLine();
            }
            Console.WriteLine();
        }

        public static double ParamsArray(params double[] param)
        {
            double total = 0.0;
            foreach (var element in param)
            {
                total += element;
            }
            return total;
        }

        static void Main(string[] args)
        {
            int[,] rectangular = { { 1, 2, 3 }, { 4, 5, 6 } };
            int[][] jagged ={new int[]{1,2},
                             new int[]{3},
                             new int[]{4,5,6}};
            OutputArray(rectangular);
            OutputJaggedArray(jagged);

            double[] paraArray = new double[] { 1, 2, 3 };
            Console.Write("{0}\n", ParamsArray(paraArray));

            Console.ReadLine();
        }
    }
}

输出结果如下：
