反序列化到JSON匿名类型的列表 [英] deserialize json into list of anonymous type

问题描述

我有一个JSON如下：

 [{一：B，C：D}，{一：E，C：F}， {一个：G，C：H}]
 

现在我想deserilize到匿名类型为foo

的对象的列表，这

 无功富=新{A =的String.Empty，C =的String.Empty};
 

在code是：

  ServiceStackJsonSerializer Jserializer =新ServiceStackJsonSerializer（）;
  动态的foo = Jserializer.Deserialize＆LT;名单，LT; foo.GetType（）＆GT;＆GT;（jsonString）;
 

但无法正常工作。

更新：

替换 ServiceStack 与的JavaScriptSerializer 并通过词典[] 解决而不需要的问题匿名键入

 的JavaScriptSerializer jSerializer =新的JavaScriptSerializer（）;
        变种FOOS = jSerializer.Deserialize＆所述;词典＆下;串，对象＆gt; []≥（jsonString）;
 

解决方案

我不知道 Jserializer 类是什么，但我知道的<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.script.serialization.javascriptserializer.aspx\"相对=nofollow> 的JavaScriptSerializer 类。不幸的是，它不支持反序列化到匿名类型。你必须创建一个具体类型是这样的：

 类Foo
{
    公共字符串{搞定;组; }    公共串c {搞定;组; }
}
 

使用以下code为我工作：

 常量字符串JSON =
    @[{一个：B，C：d的}，{，一个，：，e的，C： F}，{，一个，：，G，C：H}];VAR FOOS =新的JavaScriptSerializer（）反序列化＆LT;富[]＆GT;（JSON）;
 

变量 FOOS 将包含富实例的数组。

I have a json as below :

  "[{"a":"b","c":"d"},{"a":"e","c":"f"},{"a":"g","c":"h"}]"

now I want to deserilize this into a list of objects of anonymous type "foo"

  var foo=new { a=string.empty , c=string.empty };

the code is :

  ServiceStackJsonSerializer Jserializer = new ServiceStackJsonSerializer();
  dynamic foos = Jserializer.Deserialize<List<foo.GetType()>>(jsonString);

but not working .

update :

replacing ServiceStack with JavascriptSerializer and passing dictionary[] solved the problem without need to anonymous Type

        JavaScriptSerializer jSerializer = new JavaScriptSerializer();
        var Foos = jSerializer.Deserialize<Dictionary<string, object>[]>(jsonString);

解决方案

I don't know what the Jserializer class is, but I do know of the JavaScriptSerializer class. Unfortunately, it doesn't support deserialization into anonymous types. You'll have to create a concrete type like this:

class Foo
{
    public string a { get; set; }

    public string c { get; set; }
}

Using the following code worked for me:

const string json =
    @"[{""a"":""b"",""c"":""d""},{""a"":""e"",""c"":""f""},{""a"":""g"",""c"":""h""}]";

var foos = new JavaScriptSerializer().Deserialize<Foo[]>(json);

the variable foos will contain an array of Foo instances.
