7.写出程序的输出结果 public abstract class A {
public A() {
Console.WriteLine('A'); }
public virtual void Fun() Console.WriteLine(\n()\); } }
public class B : A {
public B()
{
Console.WriteLine('B'); }
public new void Fun() 51{
Console.WriteLine(\n()\); }
public static void Main() {
A a = new B(); a.Fun(); } }
