将json转换为c＃对象列表

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＃将json转换为电影的c＃列表：

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

我的movies变量最终变成了一个计数为0的空列表。我错过了什么吗？

Answer 1

您的C＃类映射与json结构不匹配。

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);
        }
}

如果要匹配C＃结构，则可以更改JSON字符串，如下所示：

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