希望用c＃语言表达出来

定义一个车基类Vehicle，含私有成员speed，weight，派生出自行车类Bicycle，增加high成员，编程分别输出基类和派生类对象的数据成员。

class Vehicle
{
private double speed;
private double weight;
public void Show()
{
Console.Write(speed+","+weight);
}
}

class Bicycle:Vehicle
{
private double high;
public void Show()
{
Console.Write(high);
}
}

Vehicle v=new Vehicle();
v.Show();
Bicycle b=new Bicycle();
b.Show();
