转换JSON对象的C＃列表

Question

JSON字符串：

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

C＃类：

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

C＃转换JSON到电影的C＃的名单：

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

我movies变量结束了作为一个空列表与数= 0，我失去的东西吗？

Answer 1

你的C＃类的映射不匹配JSON结构。

解决方案：

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);
        }
}

Answer 2

如果你想匹配的C＃结构，可以改变JSON字符串是这样的：

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