创建一个抽象类:
public abstract class Test {
public abstract void Print();//输出信息
}
创建输出123的测试类
public class Test1: Test {
public override void Print()
{
Console.WriteLine("123");
}
}
创建输出456的测试类
public class Test2: Test {
public override void Print()
{
Console.WriteLine("456");
}
}
创建抽象工厂类
/// <summary> /// 抽象工厂类 /// </summary> public abstract class Creator { // 工厂方法 public abstract TestCreateTest(); }
创建123的工厂类
public class Test1Factory : Creator {
public override Test TestCreateTest()
{
return new Test1();
}
}
创建456的工厂类
public class Test2Factory : Creator {
public override Test TestCreateTest()
{
return new Test2();
}
}
客户端调用的时候:
Creator creator1= new Test1Factory ();
Creator creator2= new Test2Factory ();
Test t1 = Test1Factory .TestCreateTest();
t1.Print();
Test t2 = Test2Factory .TestCreateTest();
t2 .Print();
如果需求需要增加,这时候只需要在创建789的类,和相应的工厂类就可以了
