c# - Access DisplayName in xaml

Question

How can i access DisplayName's value in XAML?

I've got:

public class ViewModel {
  [DisplayName("My simple property")]
  public string Property {
    get { return "property";}
  }
}

XAML:

<TextBlock Text="{Binding ??Property.DisplayName??}"/>
<TextBlock Text="{Binding Property}"/>

Is there any way to bind DisplayName in such or simmilar way? The best idea will be to use this DisplayName as key to Resources and present something from Resources.

I would use a markup extension:

public class DisplayNameExtension : MarkupExtension
{
    public Type Type { get; set; }

    public string PropertyName { get; set; }

    public DisplayNameExtension() { }
    public DisplayNameExtension(string propertyName)
    {
        PropertyName = propertyName;
    }

    public override object ProvideValue(IServiceProvider serviceProvider)
    {
        // (This code has zero tolerance)
        var prop = Type.GetProperty(PropertyName);
        var attributes = prop.GetCustomAttributes(typeof(DisplayNameAttribute), false);
        return (attributes[0] as DisplayNameAttribute).DisplayName;
    }
}

Example usage:

<TextBlock Text="{m:DisplayName TestInt, Type=local:MainWindow}"/>

public partial class MainWindow : Window
{
   [DisplayName("Awesome Int")]
   public int TestInt { get; set; }
   //...
}
