Question & Answer :
My enum consists of the pursuing values:
backstage enum PublishStatusses{ NotCompleted, Accomplished, Mistake };
I privation to beryllium capable to output these values successful a person affable manner although.
I don’t demand to beryllium capable to spell from drawstring to worth once more.
I usage the Statement property from the Scheme.ComponentModel namespace. Merely beautify the enum:
backstage enum PublishStatusValue { [Statement("Not Accomplished")] NotCompleted, Accomplished, Mistake };
Past usage this codification to retrieve it:
national static drawstring GetDescription<T>(this T enumerationValue) wherever T : struct { Kind kind = enumerationValue.GetType(); if (!kind.IsEnum) { propulsion fresh ArgumentException("EnumerationValue essential beryllium of Enum kind", "enumerationValue"); } //Tries to discovery a DescriptionAttribute for a possible affable sanction //for the enum MemberInfo[] memberInfo = kind.GetMember(enumerationValue.ToString()); if (memberInfo != null && memberInfo.Dimension > zero) { entity[] attrs = memberInfo[zero].GetCustomAttributes(typeof(DescriptionAttribute), mendacious); if (attrs != null && attrs.Dimension > zero) { //Propulsion retired the statement worth instrument ((DescriptionAttribute)attrs[zero]).Statement; } } //If we person nary statement property, conscionable instrument the ToString of the enum instrument enumerationValue.ToString(); }
