目测没错，这个编译器有问题。。。？

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

namespace projGetMaxScore
{
    class Program
    {
        static void Main(string[] args)
        {
            string[,] result=new string[,]{{"吴松","89"},{"铁东宇","90"},{"伏晨","98"},{"陈陆","56"},{"周蕊","60"},{"林日鹏","91"},{"何昆","93"},{"关欣","85"}}；
            string temp="";
            int maxscore=0;
            for(int i=0;i<result.GetLongLength(0);i++)
            {
                if(int.Parse(result[i,1])>maxscore)
                {
                    temp=result[i,0];
                    maxscore=int.Parse(result[i,1]);
                }
            }
          Console.WriteLine("分数最高的是{0},分数是{1}",temp,maxscore);
        }
    }
}
