出问题了（Identifier expected）

以下是代码：

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

namespace projAboveAvg
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] N = new string[8] { "景珍","林慧洋", "成蓉", "洪南昌", "龙玉民", "单江开", "田武山", "王三明" };
            int[] SCORE = new int[8] {90,65,88,70,46,81,100,68};
            int sum=0,avg;
            for (int i = 0; i < SCORE.Length; i++)
            {
                sum += SCORE[i];
            }
            avg = sum / SCORE.Length;
            Console.Write("平均分是" + avg + ", ");
            Console.WriteLine("高于平均分的有：");
            for (int cb = 0; cb < SCORE.Length; cb++)
            {
                if (SCORE[cb] > avg)
                    Console.Write(N.[cb] + " ");
            }
        }
    }
}

错误是这个：
