通过继承泛型类实现输出学生信息

class BStuInfo<T>
{
public T ID; //声明学生编号字段
public T Name; //声明姓名字段
public T Sex; //声明性别字段
public T Age; //声明年龄字段
public T Birthday; //声明生日字段
public T Grade; //声明班级字段
}
class HStuInfo<T>:BStuInfo<T> //继承自BStuInfo泛型类
{
public T Chinese; //声明语文成绩字段
public T Math; //声明数学成绩字段
public T English; //声明英语成绩字段
}

private void button1_Click(object sender, EventArgs e)
{
HStuInfo<string> hstuinfo = new HStuInfo<string>();
hstuinfo.ID = "1";
hstuinfo.Name = "小王";
hstuinfo.Sex = "男";
