Mit dieser Extension method ist es möglich die Beschreibung einer Property (mittels DataAnnotation) z.B. auf der GUI in WPF auszugeben.

///
/// Extends PropertyInfo with a method to show the description of the property in [Description("HERE!")]
/// 
///The property info
/// The description text of the property if available.
internal static string GetPropertyDescription(this PropertyInfo propertyInfo)
{
	object[] attribArray = propertyInfo.GetCustomAttributes(false);

	if (attribArray.Length == 0)
	{
		return propertyInfo.ToString();
	}
	else
	{
		DescriptionAttribute attrib = attribArray[0] as DescriptionAttribute;
		return attrib.Description;
	}
}

var someProperty = typeof(GPN.Configuration).GetProperties().First();
var descriptionOfProperty = someProperty.GetPropertyDescription();
