求平均成绩(网上找的，仅自用，非原创)

using System;
class Score
{
public void score(int sequence_number)
{
int sum=0;
int[] student=new int [5];
for(int i=0;i<=4;i++)
{
Console.WriteLine ("请输入第{0}个学生的第{1}门功课:",sequence_number,i+1);
student[i]=int.Parse (Console.ReadLine ());
}
for(int index=0;index!=student.Length;index++)
{
sum+=student[index];
}
Console.WriteLine ("该生的平均成绩为"+sum/5);
}
}
class Average
{
public static void Main()
{
for(int i=1;i<=5;i++)
{
Score s=new Score ();
s.score (i);
}
}
}
