关于状态模式

[fedoriri]

自己编了个例子，但感觉似是而非，不是那么自然，有哪里不对或者可以优化的地方?请模式达人给看下。
public interface State{
void wear();
State changState();
}
public class SpringState : State {
public void wear() {
Console.WriteLine("Everyone wear outercoat.");
}
public State changState() {
return new SummerState();
}
}

public class SummerState : State {
public void wear() {
Console.WriteLine("Everyone wear shirts");
}
public State changState() {
return new AutumnState();
}
}
public class AutumnState : State {
public void wear() {
Console.WriteLine("Everyone wear sweater.");
}
public State changState() {
return new WinterState();
}
}
public class WinterState : State {
public void wear() {
Console.WriteLine("Everyone wear jacket.");
}
public State changState() {
return new SpringState();
}
}

public class Person {
private State current;
public Person() {
current = new SpringState();
}

public void wear() {
current.wear();
}
public void senseSeason() {
current =current.changState();
}

}
class client {
static void Main(string[] args) {
Person p = new Person();
p.wear();

p.senseSeason();
p.wear();

p.senseSeason();
p.wear();

p.senseSeason();
p.wear();
}
}

是不太对！ 是我写的话，我会写月份 比如月份是2的话就触发春天那个state。 public void wear(State state) { if(state.month<3) { Console.WriteLine("Everyone wear outercoat."); } else { changState(); state.wear(); } }
