使用数组

使用数组>数组的长度获取，数组的遍历

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

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            //获取数组长度
            Console.WriteLine("Hello,VS");
            string[] csharpBooks = { "book1","book2","book3"};
            int bookLength = csharpBooks.Length;//获取所有维度的元素的个数
            Console.WriteLine("一维数组的长度"+bookLength);

            string[,] csharpBooks2 = { { "book1", "book2","book5" }, { "book3", "book4" ,"book6"} };
            int bookLength2=csharpBooks2.Length;
            Console.WriteLine("二维数组的所有元素个数" + bookLength2);
            Console.WriteLine("二维数组的指定维度的元素个数" + csharpBooks2.GetLength(0));
            

            //for循环遍历一维数组
            for (int index = 0; index <= csharpBooks.Length - 1; index++)
            {
                string csharpBook = csharpBooks[index];
                Console.WriteLine("for循环遍历一维数组,循环结果  " + csharpBook);
            }

            //foreach循环遍历一维数组
            foreach (string csharpBook2 in csharpBooks)
            {
                Console.WriteLine("foreach循环遍历一维数组,循环结果  " + csharpBook2);
            }
