Question

C#中继承抽象类 override是写在子类前还是写在要重写的方法前?比如：

public abstract class Area
{
public abstract void area();
}
public override class Circle : Area
{
private double r;

public double R
{
get { return r; }
set { r = value; }
}
public Circle(double x)
{
this.r = x;
}

public void area()
{
Console.WriteLine("圆的面积为：" + 3.14 * r * r);
}
}

Answer 1

override 修饰符是为了扩展或修改继承的方法、属性、索引器或事件的抽象实现或虚实现。它写在方法前

Answer 2

override是重写的意思
