How do I return the ancestors of an object with LINQ?
- by Chris
I have a District class that looks like this:
public class District
{
public int Id { get; set; }
public string Name { get; set; }
public District Parent { get; set; }
public IEnumerable<District> Ancestors { get { /* what goes here? */ } }
}
I would like to be able to get a list of each District's ancestors. So if District "1.1.1" is a child of District "1.1", which is a child of District "1", getting Ancestors on District "1.1.1" would return a list that contains the District objects whose names are "1.1" and "1".
Does this involve the yield return statement (I never totally understood that)?
Can it be done in one line?
