Console.WriteLine("分数最高是{0},分数是{1}",Topnum,Maximum);

只能说是里面有两个中文逗号，记住{0}后面一个逗号，{1}后面还有一个逗号

我的也显示打印正确可就是不过关 中文逗号也试了

  string[] a = new string[]{ "吴松", "钱东宇", "伏晨", "陈陆", "周蕊", "林日鹏", "何昆", "关欣"  };
            int[] b = new int[] { 90, 90, 98, 56, 60, 91, 93, 95 };
            int max=0;
            int c=0;
            for (int x = 0; x < a.Length; x++)
            {
                if (b[x] > max)
                {
                    max = b[x];
                    c = x;
                }             
            }
                Console.Write("分数最高的{0}，分数是{1}",a[c],b[c]);
