I have this table using Entity Framework code first approach :
public class WebsitePart
{
public WebsitePart()
{
SubParts = new HashSet<WebsitePart>();
}
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
public Nullable<int> ParentId { get; set; }
[StringLength(100)]
[Index("UQ_WebsitePart_Key", IsUnique = true)]
public string Key { get; set; }
public virtual WebsitePart Parent { get; set; }
public virtual ICollection<WebsitePart> SubParts { get; set; }
}
I need after getting the list of WebsiteParts to map it into List of another model where each element of this list has ParentId=null and down to the end of its grandsons(traversing) .
This the model I want to map to:
public class WebPartViewDto
{
public int Id { get; set; }
public string Key { get; set; }
public IList<WebPartViewDto> SubWebParts { get; set; }
}
Could you please show me how to map it with performance is taken into account?
