convert json to c# list of objects

Question

Json string:

{"movies":[{"id":"1","title":"Sherlock"},{"id":"2","title":"The Matrix"}]}

C# class:

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

C# converting json to c# list of Movie's:

JavaScriptSerializer jss = new JavaScriptSerializer();
List<Movie> movies = jss.Deserialize<List<Movie>>(jsonString);

My movies variable is ending up being an empty list with count = 0. Am I missing something?

Perhaps you should name first json node as Movie so it corresponds to the Movie class? — Dmitrii Lobanov

Your c# class mapping doesn't match with json structure.

Solution :

class MovieCollection {
        public IEnumerable<Movie> movies { get; set; }
}

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

class Program {
        static void Main(string[] args)
        {
                string jsonString = @"{""movies"":[{""id"":""1"",""title"":""Sherlock""},{""id"":""2"",""title"":""The Matrix""}]}";
                JavaScriptSerializer serializer = new JavaScriptSerializer();
                MovieCollection collection = serializer.Deserialize<MovieCollection>(jsonString);
        }
}

If you want to match the C# structure, you can change the JSON string like this:

{[{"id":"1","title":"Sherlock"},{"id":"2","title":"The Matrix"}]}
