希望能更优化下

string[,] scores = new string[8,2]{{"景珍","90"},{"林惠洋","65"},{"成蓉","88"},{"洪南昌","70"},{"龙玉民","46"},{"单江开","81"},{"田武山","100"},{"王三明","68"}};

int avg=0;//平均分

for(int i=0;i<scores.GetLongLength(0);i++){

avg+=Convert.ToInt32(scores[i,1]);

}

avg = avg/8;

string name ="";//高于平均分的名字

for(int i=0;i<scores.GetLongLength(0);i++){

if(Convert.ToInt32(scores[i,1])>=avg){

name+=scores[i,0]+" ";

}

name = name.Trim(' ');

Console.WriteLine("平均分是{0}，高于平均分的有：",avg);

Console.WriteLine(name);
