Get XmlEnumAttribute from enum

Question

I have enum:

public enum Operation {
    /// 
    [System.Xml.Serialization.XmlEnumAttribute(\"01\")]
    Item01,

    /// 
          


        

Answer 1

You could create an helper (static) class, with this extension method

public static string GetXmlEnumAttributeValueFromEnum(this TEnum value) where TEnum : struct, IConvertible
{
    var enumType = typeof(TEnum);
    if (!enumType.IsEnum) return null;//or string.Empty, or throw exception

    var member = enumType.GetMember(value.ToString()).FirstOrDefault();
    if (member == null) return null;//or string.Empty, or throw exception

    var attribute = member.GetCustomAttributes(false).OfType().FirstOrDefault();
    if (attribute == null) return null;//or string.Empty, or throw exception
    return attribute.Name;
}

usage

var res = Operation.Item1;
var result = res.GetXmlAttributeValueFromEnum();
