switch+ 枚举

枚举：

public enum ColorTypeEnum{  
       GREEN,  
       RED,  
       ORANGE,  
       WHITE,  
       BLACK  
}  

错误示范：   An enum switch case label must be the unqualified name of an enumeration constant

private void TestEnum(ColorTypeEnum colorEnum){  
      switch (colorEnum){  
         case ColorType.GREEN:  // 编译时报错
              break;  
         case ColorType.RED:    // 编译时报错
              break;  
         case ColorType.ORANGE:    // 编译时报错
              break;  
         case ColorType.WHITE:    // 编译时报错
              break;  
         case ColorType.BLACK:    // 编译时报错
              break;  
         default:  
   
      }  
}  

正确使用（正确写法应该是case后面的enum项不要带ColorType）

private void TestEnum(ColorType type){  
      switch (type){  
          case GREEN: 
              break;  
          case RED:    
              break;  
          case ORANGE:    
              break;  
          case WHITE:    
              break;  
          case BLACK:   
              break;  
          default:  
   
      }  
}
