最佳答案

可以在Achievement类中新建一个Name属性。

private string _name = string.Empty;

public string Name
{
　　get { return _student.Name; }
}

其他回答(2)

思路: 在这你只有将Achievement 对象 Student 对象关联起来。像数据库中表查询或表连接似的。。

现在已经连起来了我已经用Nhibernate读出Achievement了并且也可以通过Achievement的属性访问到Student但是不知道怎么绑定到DataGridView里啊

这里的两个类肯定是有关系的吧。
