How to return enum's values marked with custom attribute using C# -

i have enum members marked custom attribute like:

public enum videocliptypeenum : int {     exhibitions = 1,      tv = 2,      [cliptypedisplayattribute(false)]     content = 3 } 

my attribute is:

public class cliptypedisplayattribute : descriptionattribute     {         #region private variables          private bool _treataspublictype;          #endregion          #region ctor          public cliptypedisplayattribute(bool treataspublictype)         {             _treataspublictype = treataspublictype;         }          #endregion          #region public props          public bool treataspublictype         {                         {                 return _treataspublictype;             }             set             {                 _treataspublictype = value;             }         }          #endregion     } 

what best way of getting values of members marked custom attribute list?

try this

var values =      f in typeof(videocliptypeenum).getfields()     let attr = f.getcustomattributes(typeof(cliptypedisplayattribute))                 .cast<cliptypedisplayattribute>()                 .firstordefault()     attr != null     select f; 

this return fieldinfo enum value. raw value, try this.

var values =      ... // same above     select (videocliptypeenum)f.getvalue(null); 

if want filter property of attribute, can too. this

var values =      ... // same above     attr != null && attr.treataspublictype     ... // same above 

note: works because enum values (e.g. videocliptypeenum.tv) implemented static, constant fields of videocliptypeenum internally.

to list<int> use this

var values =      (from f in typeof(videocliptypeenum).getfields()      let attr = f.getcustomattributes(typeof(cliptypedisplayattribute))                  .cast<cliptypedisplayattribute>()                  .firstordefault()      attr != null      select (int)f.getvalue(null))     .tolist();
