How to deserialize nested XML?

I'm new into this, and I've been searching around similar questions and that's all I got for now. I want to keep XML hierarchy and make it a something that could be iterated.

static void Main(string[] args)
        {
            List<Movie> movies = DeserializeFromXML();
            for (int i = 0; i < movies.Count; i++)
            {
                Console.WriteLine(movies[i]);
            }
        }

.

static List<Movie> DeserializeFromXML()
        {
            XmlSerializer deserializer = new XmlSerializer(typeof(List<Movie>));
            TextReader textReader = new StreamReader(@"C:\movies.xml");

            List<Movie> movies;
            movies = (List<Movie>)deserializer.Deserialize(textReader);
            textReader.Close();

            return movies;
        }

.

public class Movie
{
  public string Name
  { get; set; }
}

.

<?xml version="1.0" encoding="utf-8"?>
<Favorites>
  <User>
    <Name>User 1 Name</Name>
    <Movie>
      <Name>Movie 1 Name</Name>
      <Actor>
        <Name>Actor Name</Name>
      </Actor>
      <Actor>
        <Name>Actor Name</Name>
      </Actor>
    </Movie>
    <Movie>
      <Name>Movie 2 Name</Name>
      <Actor>
        <Name>Actor Name</Name>
      </Actor>
    </Movie>
  </User>
    <User>
    <Name>User 2 Name</Name>
    <Movie>
      <Name>Movie 1 Name</Name>
      <Actor>
        <Name>Actor Name</Name>
      </Actor>
      <Actor>
        <Name>Actor Name</Name>
      </Actor>
    </Movie>
    <Movie>
      <Name>Movie 2 Name</Name>
      <Actor>
        <Name>Actor Name</Name>
      </Actor>
    </Movie>
  </User>
</Favorites>

My XML looks like that. This works and I can actually read the first level, but cant reach the lower levels yet.

That is because you deserialize User into Movie, that is most likely the origin of your problem...

Your User class should contain a list of Movie. I would also recommend to fold the Movies into one XML list element since that makes deserializing easier.
