C # enumeration Conversion

When applying enumeration, you often need to convert enumeration and numerical values. Sometimes it is necessary to convert it into a corresponding Chinese character. The following describes a method.

First, create an enumeration:

 
/// <Summary>
///Color
/// </Summary>
Public EnumColortype
{
/// <Summary>
///Red
/// </Summary>
Red,

/// <Summary>
///Blue
/// </Summary>
Bule,

/// <Summary>
///Green
/// </Summary>
Green
}
 

 

Obtain the enumerated value:

 IntCode = colortype. Red. gethashcode ();
 

Obtain the enumerated name with a numerical value:

 
StringName1 = colortype. Red. tostring ();
//Or
StringName2 = enum. parse (Typeof(Colortype), Code. tostring (). tostring ();
 

The enumerated name obtained above is in English. If you want to obtain the corresponding Chinese explanation, you can use attribute to implement it,CodeAs follows:

  //    
   //   color 
   //    
   Public   Enum  colortype 
{< br>  ///     
   //   Red 
   ///    
  [description ( "
     Red   ")] 
 Red, 
  //    
  / //   blue 
   ///     
  [description ( "  blue  " )] 
 Bule, 
  //    
  / //   green 
   ///     
  [description ( "  green  " )] 
 green 
}

 

In enumeration, add description and create a class. You can use the following method to convert enumeration into a corresponding Chinese explanation:

  Public   Static   Class Enumdemo
{
 Private   Static   String Getname (system. type T, Object V)
{
 Try 
{
 Return Enum. getname (T, V );
}
 Catch 
{
 Return   "  Unknown " ;
}
}

 ///   <Summary>  
  ///  Returns the description of the specified value of the specified enumeration type.
  ///   </Summary>  
  ///   <Param name = "T">  Enumeration type  </Param>  
  ///   <Param name = "v">  Enumerated Value  </Param>  
  ///   <Returns> </returns>  
          Public  Static   String Getdescription (system. type T, Object V)
{
 Try 
{
Fieldinfo ofieldinfo = T. getfield (getname (T, V ));
Descriptionattribute [] attributes = (descriptionattribute []) ofieldinfo. getcustomattributes ( Typeof (Descriptionattribute ), False );
 Return (Attributes. length> 0 )? Attributes [ 0 ]. Description: getname (T, V );
}
 Catch 
{
 Return   "  Unknown  " ;
}
}
}

The call method is as follows:

 
StringName3 = enumdemo. getdescription (Typeof(Colortype), colortype. Red)
 

What name3 gets is "red ".
