重用托管代码中的Classic COM 组件
Collapse通过使用DOS命令行里的以下命令，你可以编译上面的程序。
using System;
using MyFlyerMetadata;
public class Bird : Flyer
{
public class Airplane : Flyer
{
public override String TakeOff() {
return "Airplane::TakeOff - This is .NET taking off";
public override String Fly() {
System.Console.WriteLine(base.Fly());
return "Airplane::Fly - This is .NET in the skies";
public class FlightController
{
public static void Main(String[] args)
{
Bird falcon = new Bird();
System.Console.WriteLine("BIRD: CLEARED TO TAKE OFF");
System.Console.WriteLine(falcon.TakeOff());
System.Console.WriteLine(falcon.Fly());
Airplane skyliner = new Airplane();
System.Console.WriteLine("AIRPLANE: CLEARED TO TAKE OFF");
System.Console.WriteLine(skyliner.TakeOff());
System.Console.WriteLine(skyliner.Fly());
}/* 结束 Main */
}/* 结束FlightController */
csc /target:exe /out:FlightClient.exe /r:MyFlyerMetadata.dll FlightClient.cs运行上面的程序，就能给你提供下面的输出。
BIRD: CLEARED TO TAKE OFF使用Bird和 Airplane 托管类型的使用者不需要知道这些类型是通过继承来重用现有的COM组件。如果必要的话，在COM 组件中，托管类型用它自己的执行覆盖所有的方法。这个重用模式，也就是托管代码从非托管代码继承的地方，被称作混合模式继承重用模式。
CFlyer::TakeOff - This is COM taking off
CFlyer::Fly - This is COM in the skies
AIRPLANE: CLEARED TO TAKE OFF
Airplane::TakeOff - This is .NET taking off
CFlyer::Fly - This is COM in the skies
Airplane::Fly - This is .NET in the skies
