有没有办法让枚举显示空间和图像？

Question

I am using enum for my group description in listview and I am trying to make it display some more user friendly text but I getting an error which says cannot implicitly convert type string to Mærke

Enum

public enum Mærke { 
 Alfa_Romeo,
 Audi,
 Aston_Martin__________________________________________________________5x114,
BMW,
 Chervolet,
Chrysler,
Citroën,
Daewoo,
Daihatsu,
Dodge,
Ferrari };
public Mærke mærke { get; set; }

Class

public class biler
{
    public string billed { get; set; }

    public string Model { get; set; }

    public string Type { get; set; }

    public string Årgang { get; set; }

    public string Krydsmål { get; set; }

    public double ET { get; set; }

    public double centerhul { get; set; }

    public string bolter { get; set; }

    public string hjul { get; set; }
     
    public Mærke mærke { get; set; }

}

List

  items.Add(new biler() { billed = "img/Biler/aston martin.png", Model = "DB9", Årgang = "03-", Krydsmål = "5x114.3", ET = 62.5, centerhul = 68.1, bolter = "M14x2", mærke = Mærke.Aston_Martin__________________________________________________________________________________________________5x114 });
 CollectionView view = (CollectionView)CollectionViewSource.GetDefaultView (hjuldata.ItemsSource);
PropertyGroupDescription groupDescription = new PropertyGroupDescription("mærke");           
view.GroupDescriptions.Add(groupDescription);

Answer 1

var mærke = Merke.Alfa_Romeo; // example
var withSpaces = mærke.ToString().Replace("_", " ");

This should solve it for you. There's nothing built-in to do that so you COULD write an extension method like such:

public static string WithSpaces(this enum theEnum){
  return theEnum.ToString().Replace("_", " ");
}

and then just use that in your code:

var mærke = Mærke.Alfa_Romeo.WithSpaces();

Answer 2

this should do it if that is what you are looking for and as for the picture i dont think headers supports that

using System.Reflection;
public static class EnumExtensions
{

    public static string DisplayName(this Enum value)
    {
        FieldInfo field = value.GetType().GetField(value.ToString());

        EnumDisplayNameAttribute attribute
                = Attribute.GetCustomAttribute(field, typeof(EnumDisplayNameAttribute))
                    as EnumDisplayNameAttribute;

        return attribute == null ? value.ToString() : attribute.DisplayName;
    }
}

public class EnumDisplayNameAttribute : Attribute
{
    private string _displayName;
    public string DisplayName
    {
        get { return _displayName; }
        set { _displayName = value; }
    }
}

public enum Mærke 
{
    [EnumDisplayName(DisplayName = "Alfa Romeo 5x114")]
    Alfa_Romeo,

public string mærke { get; set; }
mærke = Mærke.Alfa_Romeo.DisplayName()
