Try this: using System; using System.Reflection; public class PropertyAttribute : Attribute { private string value; public PropertyAttribute(string value) { this.value = value; } } public class TitleAttribute : Attribute { private string value; public TitleAttribute(string value) { this.value = value; } } public enum Locations { [Property ("job-view")] [Title ("analyics-job-view")] JobViewValue } class Program { static void Main() { Type enumType = typeof(Locations); Type attribType = typeof(PropertyAttribute); string attribValue = "job-view"; BindingFlags bf = BindingFlags.Public | BindingFlags.Static; FieldInfo[] fia = enumType.GetFields(bf); bool found = false; foreach(FieldInfo fi in fia) { foreach(CustomAttributeData cad in fi.CustomAttributes) { if (cad.AttributeType == attribType) { foreach(CustomAttributeTypedArgument cata in cad.ConstructorArguments) { if (cata.Value.ToString() == attribValue) { Console.WriteLine("Found : {0} = {1}", fi.Name, (int)fi.GetValue(null)); found = true; goto end; } } } } } end: if (!found) { Console.WriteLine("No corresponding enum member was found"); } Console.ReadKey(); } } The output should be: Found : JobViewValue = 3
