c#中Enum的转换(downmoon)

一、Enum的定义

  public   enum  UserRolesType 
     ... { 
        
        UnKnown = 0 ,
        BaseSimple = 70 ,
        BaseBasic = 71 ,
        BaseExtend = 72 ,
        BaseBasic2 = 88 ,
        BaseSimple2 = 89 ,
        BaseExtend2 = 90
}

方法一：
根据ID获取枚举对象

protected  UserRolesType GetEnum( int  t)
     ... {
         bool  isInEnum  =   false ;
       UserRolesType c  =  UserRolesType.UnKnown;
         if  (t  >   0 )
         ... {

             foreach ( int  i  in  Enum.GetValues( typeof (UserRolesType)))
             ... {
                 if  (i  ==  t)
                 ... {
                     // this.Debug(t.ToString(), "");
                    c  = (UserRolesType)Enum.Parse( typeof (UserRolesType),i.ToString());
                    isInEnum  =   true ;
                     return  c;
                     // (Colors)Enum.Parse(typeof(Colors), "Red, Yellow");
                }
               
            }
             if  (isInEnum  ==   false )
             ... {
                 return  UserRolesType.UnKnown;
            }


        }
         return  c;

    }

方法二：根据ID获取枚举名称

  protected   string  GetEnumName( int  s)
     ... {
         string  str = Enum.GetName( typeof (UserRolesType), s);
         if  (str  ==   null )
         ... {
            str  =  UserRolesType.UnKnown.ToString();
        }
        return  str;
    }
