设计一个医院

發布時間：2023/12/1 编程问答 55 豆豆

生活随笔收集整理的這篇文章主要介紹了设计一个医院小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

源于個人網站：http://programmer.2008red.com/programmer/article_647_777_1.shtml

收到一封來自Exoweb的郵件，讓去面試（敗的很慘，呵呵。過了好長時間了，都忘記這事了，結果這公司來了郵件，說不能提供給我職位，還安慰我。不過就不過是了，弄這些做什么，害我出了一肚子火），就查了查這個公司。以前去面試過的前輩提到了他們會讓我們設計醫院，學校之類的東東，覺得應該先自己嘗試做一下，就做了！

?病人Patient分別在各個部門掛號，交費，然后檢查身體,具體的動作由各個部門去做（operation)。

?病人與部門分開，使用組合/聚合關系，個人覺得有點橋梁模式的意思！

假如將來醫院增加新的部門，只要在Patient和Department下增加單層的子類就可以了。

具體代碼：

using System;
using System.Collections.Generic;
using System.Text;
using System.Collections;

namespace Hospital
{
??? delegate void UpdateDelegate();

??? abstract class? Patient
??? {
??????? protected string name;

??????? public string Name
??????? {
??????????? get { return this.name;? }
??????????? set { this.name = value; }
??????? }

????????????
??? }

??? class Register:Patient
??? {
??????
??? }

??? class Payer:Patient
??? {
??????
??? }

??? class Inspector:Patient
??? {
??????
??? }

??? interface Department
??? {
??????? void Operation();
??? }

??? class Registe:Department
??? {
??????? public Patient patient;

??????? public Registe(Patient register)
??????? {
??????????? this.patient = register;
??????? }

??????? public void Operation()
??????? {
??????????? Console.WriteLine(this.patient.Name + "已登記！");
??????? }
???????
??? }

??? class Pay:Department
??? {
??????? public Patient patient;

??????? public Pay(Patient payer)
??????? {
??????????? this.patient = payer;
??????? }

??????? public void Operation()
??????? {
??????????? Console.WriteLine(this.patient.Name+"已交錢！");
??????? }
??? }

??? class Inspecte:Department
??? {
??????? public Patient patient;

??????? public Inspecte(Patient inspector)
??????? {
??????????? this.patient = inspector;
??????? }

??????? public Patient Patients
??????? {
??????????? get { return this.patient; }
??????????? set { this.patient = value; }
??????? }

??????? public void Operation()
??????? {
??????????? Console.WriteLine(this.patient.Name + "已治療！");
??????? }
??? }

??? class Treatment
??? {
??????? public Department[]? dm=new Department[3];
????????????
??????? public Treatment(Patient d1,Patient d2,Patient d3)
??????? {
??????????? dm[0]=new Registe(d1);
??????????? dm[1] = new Pay(d2);
??????????? dm[2] = new Inspecte(d3);
??????? }

??????? public void run()
??????? {
??????????? dm[0].Operation();
??????????? dm[1].Operation();
??????????? dm[2].Operation();
??????? }
??? }

??? class Program
??? {
??????? static void Main(string[] args)
??????? {

??????????? string name = "zhong";
??????????? Register r1 = new Register();
??????????? Payer p1 = new Payer();
??????????? Inspector i1 = new Inspector();
??????????? r1.Name = name;??????????
??????????? p1.Name = name;???????????
??????????? i1.Name = name;
??????????? Treatment tm = new Treatment(r1,p1,i1);
??????????? tm.run();

??????????? Console.ReadLine();
???????????
??????? }
??? }
}

掛號，交費，檢查可以設置成一個觀察者模式，在C#里當然是用委托來做最好了。

還可以設置很多病人，排隊來看病。這可以用一個Arraylist或哈希表來存儲各個病人的信息，用循環輸出。

由于這是我寫的第一個有關模式的文章，時間上也有點緊，不但上面的想法沒去實現，可能還有一些我不

知道的錯誤缺點列在其中，希望大家原諒并指正。

希望自己能盡快實現這些沒完成的想法。

和宿舍的人出去吃了個飯，今天端午，呵呵，晚上十二點回到宿舍后一點也不想睡，又開始寫了起來，呵呵！

下面為用一個ArrayList記錄病人的修改。

?? ***

?class Treatment
??? {
??????
??????? public Department[]? dm=new Department[3];
??????? public ArrayList list = new ArrayList();

??????? public void show(string name)
??????? {
??????????? Register r1 = new Register();
??????????? Payer p1 = new Payer();
??????????? Inspector i1 = new Inspector();
??????????? r1.Name = name;
??????????? p1.Name = name;
??????????? i1.Name = name;
??????????? dm[0] = new Registe(r1);
??????????? dm[1] = new Pay(p1);
??????????? dm[2] = new Inspecte(i1);
??????????? dm[0].Operation();
??????????? dm[1].Operation();
??????????? dm[2].Operation();
??????? }

??????? public void add(string name)
??????? {
??????????? list.Add(name);
??????? }

??????? public void remove(string name)
??????? {
??????????? list.Remove(name);
??????? }

??????? public void run()
??????? {
??????????? foreach (string uh in list)
??????????? {
??????????????? show(uh);
??????????? }
?????????
??????? }
??? }

??? class Program
??? {
??????? static void Main(string[] args)
??????? {
??????????? Treatment tm = new Treatment();

??????????? string name = "zhong";??????
??????????? tm.add(name);???????????????????
??????????? tm.add("liu");
?????????? // tm.remove("zhong");
??????????? tm.run();

??????????? Console.ReadLine();
???????????
??????? }
??? }

}

這塊是使用委托處理的程序：

{

? ***

?class Subject
??? {
??????? public event UpdateDelegate UpdateHandler;
??????? public void add(UpdateDelegate ud)
??????? {
??????????? UpdateHandler += ud;
??????? }

??????? public void remove(UpdateDelegate ud)
??????? {
??????????? UpdateHandler -= ud;
??????? }

??????? public void run()
??????? {???????????
??????????? if (UpdateHandler != null)
??????????????? UpdateHandler();???????????
??????? }
??? }

??? class Treatment
??? {
???????
??????? public Department[]? dm=new Department[3];
??????? public ArrayList list = new ArrayList();

??????? public Treatment(string name)
??????? {
??????????? Register r1 = new Register();
??????????? Payer p1 = new Payer();
??????????? Inspector i1 = new Inspector();
??????????? r1.Name = name;
??????????? p1.Name = name;
??????????? i1.Name = name;
??????????? dm[0] = new Registe(r1);
??????????? dm[1] = new Pay(p1);
??????????? dm[2] = new Inspecte(i1);?
??????? }

??????? public void show()
??????? {
??????????? dm[0].Operation();
??????????? dm[1].Operation();
??????????? dm[2].Operation();
??????? }
???????
??? }

??? class Program
??? {
??????? static void Main(string[] args)
??????? {
??????????? Treatment t1 = new Treatment("zhong");
??????????? Treatment t2 = new Treatment("liu");

??????????? Subject sj = new Subject();
??????????? sj.add(new UpdateDelegate(t1.show));
??????????? sj.add(new UpdateDelegate(t2.show));
????????? //? sj.remove(new UpdateDelegate(t1.show));
??????????? sj.run();
????????????
??????????? Console.ReadLine();
???????????
??????? }
??? }

}

分別實現了ArrayList和委托來處理多人的情況。也算是運用了觀察者模式了。
