oop:面向對象，全稱叫Object?oriented?programming
?*?面向對象的三大特點：1.封裝，
?*?????????????????????????2.繼承
?*?????????????????????????3.多態
?*?
?*?
?*?類的定義：實際上就是具有相同屬性和特征的一類事物的抽象集合
?*?注意：類是對象的抽象，對象是類的實例
?*?
?*?對向的定義：抽象類的實例
?*?
?*?昨天我去了工商銀行去辦銀行卡，在我前邊有50個人?、、、53
?*?
?*?1.知道了類的定義，如何定義類？
?*?????????使用系統關鍵字:(默認訪問修飾符internal)Class?+類名+{}
?*?????????注意1點：類和類屬于同級關系
?*?2.如何描述類的特征
?*???????叫字段或類成員變量
?*???????字段和普通局部變量的區別，訪問該局部變量時編譯會通過?字段不會
?*?3.實例化對象
?*??????????采用系統關鍵詞new?+?類名（）
?*???????new?關鍵字的作用：
?*?????????????1,。開辟一塊內存空間（堆區）
?*?????????????2.在開辟出來的內存空間中存對象信息（字段屬性方法）
?*????????????3.初始化對象（調用構造函數）
?*?
?*?4.如何描述類的行為
?*??????叫方法或者函數
?*?????????語法格式：修飾詞+函數返回值+函數名（方法名）（形參列表）
?*?{
?*?
?*?}
?*?5.修飾符（）
?*?????public：公開·的意思，常用于修飾類，修飾類字段，修飾類種方法
?*?????????????????就是非本類之外也可以訪問
?*?????private?：私有的，常用于修飾字段，方法，也是C#中默認的修飾符，
?*?????????????????就是只有本類才可以訪問
?*?????intrnal：程序集內部可以訪問
?*?????protected：基類&&派生類可以訪問
?*?????
?*?6.如果方法又返回值就返回方法的實際類型的返回值，關鍵字：return?+返回內容；
?*?如果方法沒有返回值,就可以省略retrun不寫，直接寫方法體內的方法快即可
?*?
?*?4種方法
?*?有參有返回值
?*?有參無返回值
?*?無參有返回值
?*?無參無返回值
?*?
?*?
?*?7.枚舉變量
?*?格式：enum+枚舉名稱
?*?{
?*?枚舉變量1,
?*??枚舉變量1,
?*??枚舉變量1
?*?}
?*?8.構造函數（重點掌握）
?*?構造函數的作用：讓一個類更完整。
?*?構造函數其實就是用來創建對象，初始化字段用的
?*?構造函數的語法格式為：修飾符+類名
?*?{
?*?}
?*?構造函數的特點：
?*?1，沒有返回值
?*?2，構造函數的名字必須和類名保持一致
?*?3，構造函數支持方法重載，換句話說就是可以有多個構造函數，但參數個數不能相同
?*?4.構造函數無法進行手動調用（系統自動調用）
?*?5.如果類中不包含構造函數，那么系統會自動為該類添加一個無參的構造函數
?*?6.如果類中存在帶有參數的構造函數，那么系統不會為該類添加無慘的構造函數
