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

Question

你能帮助我如何使用System.Runtime.Serialization.Json(不Json.NET)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样本似乎有效:

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<Book> Books { get; set; }
    [DataMember(Name="src")] public string Src { get; set; }
    [DataMember(Name="id")] public string Id { get; set; }
}

我相信你可以调整很多其他选项,但这至少应该让你开始.
