如何使用System.Runtime.Serialization.Json解析此String？

你能帮我看看如何使用System.Runtime.Serialization.Json （ 而不是Json.NET ）来获取这个tring to array中每本书的信息：

 { "books": [ {"name":"Book 1","orig":"Author 1","date":2009,"lang":"en"}, {"name":"Book 2","orig":"Author 2","date":2012,"lang":"fr"} ], "src":"lib", "id":212 } 

Answer 1

这是一个我掀起的快速示例，似乎有效：

 using System; using System.Collections.Generic; using System.IO; using System.Runtime.Serialization; using System.Runtime.Serialization.Json; class Test { static void Main() { using (Stream stream = File.OpenRead("test.json")) { var serializer = new DataContractJsonSerializer(typeof(Library)); Library library = (Library) serializer.ReadObject(stream); Console.WriteLine(library.Books[0].Name); } } } [DataContract] class Book { [DataMember(Name="name")] public string Name { get; set; } [DataMember(Name="orig")] public string Orig { get; set; } [DataMember(Name="date")] public string Date { get; set; } [DataMember(Name="lang")] public string Lang { get; set; } } [DataContract] class Library { [DataMember(Name="books")] public IList Books { get; set; } [DataMember(Name="src")] public string Src { get; set; } [DataMember(Name="id")] public string Id { get; set; } } 

我确信你可以调整很多其他选项，但这至少应该让你开始。

一般方法：

 using System.IO; using System.Runtime.Serialization.Json; using System.Text; using System.Threading.Tasks; namespace YourApp.Helpers { public class SystemSerializer:ISerializer { public T Deserialize(string json) where T : class { DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T)); using (var ms = new MemoryStream(Encoding.UTF8.GetBytes(json))) { return ser.ReadObject(ms) as T; } } public T Deserialize(Stream json) where T : class { DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T)); return ser.ReadObject(json) as T; } public async Task SerializeAsync(T obj) where T : class { DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T)); using (var ms = new MemoryStream()) { ser.WriteObject(ms, obj); ms.Position = 0; using (var sr = new StreamReader(ms)) { return await sr.ReadToEndAsync(); } } } } }
