代码风格-统一，整齐，美态

                                          代碼規範化培訓

一.           變量命名規則:

1) 類變量

1>              第一個字母小寫,並注明變量類型

2>              明確定義變量是甚麼,第一個字母大寫

3>              如: iDogqty表示整形狗數量變量

2) 函數變量

1>              必須以下划槓開頭

2>              第一個字母小寫,並注明變量類型

3>              明確定義變量是甚麼,第一個字母大寫

4>              如: _iDogqty表示整形狗數量變量

3) 循環變量

1>              必須以i , j , k

4) 常量,只讀變量

1>              所有必須大寫, 明確定義變量是甚麼

2>              最後用一個下划槓加三個大寫表示常量類型

3>              如: DOG_NAME_STR表示狗名字是字符串型

二.           類,接口,函數,枚舉等命名規則

1) 類命名規則

1>              明確定義類是甚麼,每個單詞首字母大寫

2>              如: AnimalCry表示動物叫

2) 接口命名規則

1>              明確定義接口是甚麼,每個單詞首字母大寫

2>              以大寫I開頭

3>              如: IAnimalCry表示動物叫

3) 函數命名規則

1>              明確定義函數動作,單詞首字母大寫

2>              明確定義函數是甚麼,每個單詞首字母大寫

3>              如:GetDogPropertys()表示獲取狗的屬性方法,Update,Insert,Mount,Delete等等

4) 枚舉命名規則

1>              明確定義枚舉是甚麼,每個單詞首字母大寫

2>              枚舉值都必須大寫

3>              如: AnimalType {DOG,CAT,}

5) 事件命名規則

1>              明確定義事件是甚麼,每個單詞首字母大寫

2>              如果有可能的化在事件名字加動作名他們之間加下划槓

3>              如: Dog_Eat(….)狗吃東西事件

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

三.           注釋規則

1) 單行 (//)

1>              注釋在變量後面

2>              明確干甚麼用

2) 多行 (/*  */)

1>              用在文件最開始處

2>              明確谁做甚麼在甚麼時候,為甚麼

3>              如: 圖1

3) XML  (///)

1>              用在類或函數前

2>              函數或類干甚麼用,參數說明,有返回值說明是甚麼

 

                 圖 1

四.           長字符串或SQL語句規則

1>              長度不能超過需要用戶拉動左右滾動條

2>              如無特殊情況竟可能使用Format()格式

3>              SQL語句需分組分行

4>              如:

Select *

From *

Where *

Group by *

Order by *
