????????????int?year?=?2015;//年份
????????????string?text1=(year%4==0?"閏年":"平年");
????????????//請(qǐng)?zhí)顚懘a
????????????Console.WriteLine("今年是{0}",text1);

兩種方式都是可以的

????????????int?year?=?2015;//年份
????????????string?text1;
????????????if(year%4==0)
????????????????text1="閏年";
????????????else
????????????????text1="平年";
????????????//請(qǐng)?zhí)顚懘a
????????????Console.WriteLine("今年是{0}",text1);

這段代碼是運(yùn)行成功的，貼出來代碼看一下

但是我把后面的改了也是錯(cuò)誤呀？

因?yàn)樵谳敵龅臅r(shí)候?qū)懙木褪荰EXT呀，你可以改成別的，Console.WriteLine("今年是{0}",text1)
