我已经在list里添加了学生的基本信息，并在listbox显示出来，能不能根据学号，为此学生添加成绩信息在listbox中显示呢？

可以，看下面

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace Q712947
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            for (int i = 0; i < 5; i++)
                listBox1.Items.Add(i);
        }

        private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            if (listBox1.SelectedIndex > 0)
            {
                textBox1.Text = listBox1.SelectedIndex.ToString();
                textBox2.Text = listBox1.Items[listBox1.SelectedIndex].ToString();
            }
        }

        private void button1_Click(object sender, EventArgs e)
        {
            listBox1.Items[int.Parse(textBox1.Text)] = textBox2.Text;
        }
    }
}
