哪里不對嗎？

?? static void Main(string[] args)
??????? {
??????????? int[] age =???????? ;//聲明并初始化長度為4的整形數組
??????????? //為數組元素賦值
??????????? age[0 ] = 18;
??????????? age[1 ] = 20;
??????????? age[2 ] = 23;
??????????? age[3 ] = 17;
??????????? Console.WriteLine("四名同學的年齡是：{0}、{1}、{2}、{3}", age[0 ],age[1 ],age[2 ],age[ 3]);

你并沒有對整型數組age[]進行聲明。

using?System;
using?System.Collections.Generic;
using?System.Text;

namespace?Test
{
????class?Program
????{
????????static?void?Main(string[]?args)
????????{
????????????int[]?age?=?new?int[4];//聲明并初始化長度為4的整形數組
????????????//為數組元素賦值
????????????age[0]?=?18;
????????????age[1]?=?20;
????????????age[2]?=?23;
????????????age[3]?=?17;
????????????Console.WriteLine("四名同學的年齡是：{0}、{1}、{2}、{3}",
????????????????age[0],age[1],age[2],age[3]);
????????}
????}
}
