        {
            int[] score = { 90, 65, 88, 70, 46, 81, 100, 68 };
            string[] name = { "景珍", "林惠洋", "成蓉", "洪南昌", "龙玉民", "单江开", "田武山", "王三明" };
            int sum = 0, avg;
            for (int i = 0; i < score.Length; i++)
            {
                sum += score[i];
            }
            avg = sum / score.Length;
            Console.WriteLine("平均分是{0}"+","+"高于平均分的有：",avg);
            int x;
            for (int i = 0; i < score.Length; i++)
            {
                if (score[i]>avg)
                {
                    x = i;
                    Console.Write(name[x]+" ");
                }
             
            }   
        }
    }
}

找到了问题了，匹配不过就是因为一个逗号：   Console.WriteLine("平均分是{0}"+","+"高于平均分的有：",avg);使用中文输入法的逗号。
