求路过的大神解惑？？？不知道为什么排不了序。。。

08还是10做的?

好吧，08的！

是08的，08在10,10在08的也能用啊。。。

你那个泛型的集合都没有把你输入的数据加进去，你排序的时候students这个集合里面都没有数据，当然排不了序，你要再你添加一个学生数据后加个students.add()把数据加进去！

加过了，不知道为什么老是错误？？？不会添加了？？教教我。。谢谢了。。。

我刚刚仔细看了你的代码，你这样可以用arraylist数组进行排序，这样简单，你添加的时候把student类作为一个参数添加就得了，不用象那样的，要你要坚持你那样做的也可以，不过list是个列表，你要添加排序也是可以的，还有就是你要按学号排序这个你要自己先排序好再放进去集合里读，集合是有sort排序，但是你那个是个泛型的，你用它也就默认你输入数据的顺序排序，不会达到你要的效果，这就是我的一点看法，希望对你有帮助!

add()方法只能加一个参数进去，就是说如果你要加很多个数据，那么把这些数据封装好坐一个参数传进去就行了！

for (int j=0; j <2; j++)
            {
                while (true)
                {
                    name = Microsoft.VisualBasic.Interaction.InputBox("请输入名字", "输入名字", "黄辉", -1, -1);
                    if (name == "0")
                    {
                        break;
                    }
                    else
                    {
                        alist.Add(name);
                    }
                }
                foreach (string i in alist)
                {
                    Nam = i;
                }
                while (true)
                {
                    number = Microsoft.VisualBasic.Interaction.InputBox("请输入学号", "输入学号", "1215080131", -1, -1);
                    if (number == "0")
                    {
                        break;
                    }
                    else
                    {
                        alist.Add(number);
                    }
                }
                foreach (string n in alist)
                {
                    Num = n;
                }
                while (true)
                {

                    score1 = Convert.ToInt32(Microsoft.VisualBasic.Interaction.InputBox("请输入成绩", "输入成绩", "90", -1, -1));
                    alist.Add(score1);
                    score2 = Convert.ToInt32(Microsoft.VisualBasic.Interaction.InputBox("请输入成绩", "输入成绩", "90", -1, -1));
                    alist.Add(score2);
                    break;

                }
我用过arraylist了只是表示红色的无法将类型为“System.Int32”的对象强制转换为类型“System.String”。

还是无法排序诶。。。。呜呜。。。。帮帮。。。
