c#使用student类输出学号姓名

为什么会输出 proj5-8.student?
我写的代码:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Proj5_8
{ class student
{
private int no;
private string name;
public void setno(int n)
{ no = n; }
public int getno()
{ return no; }
public void setname(string a)
{ name = a;}
public string getname()
{ return name; }
}
class Program
{
static void Main(string[] args)
{
student s1 = new student();
s1.setno(2);s1.setname("Smith");
student s2 = new student();
s2.setno(4); s2.setname("John");
student s3 = new student();
s3.setno(5); s3.setname("Mary");
student s4 = new student();
s4.setno(1); s4.setname("Cheer");
student s5 = new student();
s5.setno(3); s5.setname("Tomn");
Console.WriteLine("{0 },{1}, {2},{3},{4}", s1, s2, s3, s4, s5);
Console.ReadLine();

    }
}

}

    直接帮你改了:

    方法1.

    Console.WriteLine("{0 },{1}, {2},{3},{4}", s1, s2, s3, s4, s5);

    =>

    Console.WriteLine("{0 },{1}, {2},{3},{4}", s1.getname(), s2.getname(), s3.getname(), s4.getname(), s5.getname());

    方法2.
    在student类重写Tostring()方法:

    public override string ToString()
    {
    return getname();
    }
