1. Create an enum with a DisplayAttribute on one of its members. For example:

public enum Color
{
    [Display(Name = "Red")]
    Red,
    [Display(Name = "Green")]
    Green,
    [Display(Name = "Blue")]
    Blue
}

1. Use the GetCustomAttribute() method to get the DisplayAttribute for the enum member. For example:

var enumMember = Color.Red;
var displayAttribute = enumMember.GetType().GetCustomAttribute(typeof(DisplayAttribute));

1. The displayAttribute variable will now contain the DisplayAttribute for the enum member. You can then get the Name property of the DisplayAttribute to get the display name of the enum member. For example:

var displayName = displayAttribute.Name;

Here is an example of the complete code:

public enum Color
{
    [Display(Name = "Red")]
    Red,
    [Display(Name = "Green")]
    Green,
    [Display(Name = "Blue")]
    Blue
}
 public static void Main()
{
    var enumMember = Color.Red;
    var displayAttribute = enumMember.GetType().GetCustomAttribute(typeof(DisplayAttribute));
    var displayName = displayAttribute.Name;
    Console.WriteLine(displayName); // Red
}
