如何使用System.Runtime.Serialization.Json解析此String? [英] How to parse this String using System.Runtime.Serialization.Json?

问题描述

您能帮我如何使用System.Runtime.Serialization.Json(不是Json.NET )获取此数组中每本书的信息:

Can you help me how to use System.Runtime.Serialization.Json (not Json.NET) to get information of each book in this tring to array:

{
    "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
}

推荐答案

以下是我整理的一个快速示例，看起来很有效:

Here's a quick sample I whipped up which appears to work:

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; }
}

我确定您还有很多其他可以调整的选项，但这至少应该可以让您入门.

I'm sure there are plenty of other options you can tweak, but that should at least get you started.
