使用JSON.NET反序列化字典

问题描述

我正在使用版本4.0.8的Newtonsoft.Json，并尝试将其与Web API一起使用.所以我想用

I am using Newtonsoft.Json with version 4.0.8 and trying to use it with Web API.So I wanted to deserialize JSON with

JsonConvert.DeserializeObject<AClass>(jsonString);

这是可行的，直到我将Dictionary作为属性添加到此类并希望反序列化它.

This works until I added a Dictionary as property to this class and wanted to deserialize it.

json字符串的格式为

The json string is in the form of

{
   "Date":null,
   "AString":"message",
   "Attributes":[
                   {"Key":"key1","Value":"value1"},
                   {"Key":"key2","Value":"value2"}
                ],
    "Id":0,
    "Description":"...
}

当类型为JsonSerializationException的反序列化异常发生并出现以下消息时:" 无法将JSON数组反序列化为类型'System.Collections.Generic.Dictionary`2 [System.String，System.String]'. /em> "

When deserializing exception of type JsonSerializationException occures with message: "Cannot deserialize JSON array into type 'System.Collections.Generic.Dictionary`2[System.String,System.String]'."

我在做什么错了?

UPDATE1:当使用JSON.NET进行序列化时，我会得到以下关于字典的信息:

UPDATE1:When serializing with JSON.NET i get the following for the dictionary:

Attributes":{"key1":"value1","key2":"value2"}

似乎WebApi用不同于Json.Net的其他方式反序列化对象.服务器端，我使用以下行进行隐式反序列化:

Seems that WebApi deserializes the object in an other way than Json.Net would.Server side I use following line for implicit deserializing:

return new HttpResponseMessage<AClass>(object);

UPDATE2:作为一种解决方法，我现在开始关注在线服务器端.

UPDATE2:As a workaround I came now to following line server side.

return new HttpResponseMessage<string>(JsonConvert.SerializeObject(license).Base64Encode());

我使用Json.Net服务器端对其进行了转换，并将其作为base64编码的字符串进行传输.因此，Json.Net可以反序列化其自己的格式.

I convert it with Json.Net server side and transfer it as base64 encoded string. So Json.Net can deserialize its own format.

但是它仍然不是我想要的，理论上有什么进一步的建议吗?

But its still not that what I want, so are thery any further suggestions?

推荐答案

如果将Attributes声明为List<KeyValuePair<string, string>>
