JSON反序列化到C＃

问题描述：

我看到了很多的JSON反序列化的简单的例子，但是当涉及到​​任何东西稍微复杂一点，有一个缺乏样品。

I see a lot of simple examples of JSON DeSerialization, but when it comes to anything slightly more complex, there is a lacking of samples.

我期待从GetResponse的API的反序列化对策：

I'm looking at deserializing Responses from GetResponse's API:

简单的如

{
    "result" : {
        "updated" : "1"
    },
    "error" : null
}

另：

{
    "result" : null,
    "error"  : "Missing campaign"
}

下面是另一个更复杂的潜在反应：

Here's another more complex potential response:

{
    "result" : {
        "CAMPAIGN_ID" : { // <-- This value will be different for each Campaign
            "name"              : "my_campaign_1",
            "from_name"         : "My From Name",
            "from_email"        : "me@emailaddress.com",
            "reply_to_email"    : "replies@emailaddress.com",
            "created_on"        : "2010-01-01 00:00:00"
        }
    },
    "error" : null
}

对于最后一个，我应该我的对象是什么样子？

我最初只用做这样的事情...

I initially toyed with just doing something like this... 

 private struct GenericResult {
     public string error;
     public Dictionary<string, object> result;
 }

这会为我所有的反应变量工作，但随后访问该对象的属性我'将不得不投它，如果我没有记错

This will work for all my reponses, but then to access the object's properties I'll have to cast it, if I'm not mistaken.

我想用这样的：

JavaScriptSerializer jss = new JavaScriptSerializer();
var r = jss.Deserialize<GenericResult>(response_string);

// or... if I'm going to use a non-Generic object
var r = jss.Deserialize<GetCampaignResult>(response_string);



修改



获取数据回后，实际的结构具有一个悬挂装置。下面是一个实际的例子：

EDIT

After getting the data back, the actual structure has one hitch. Here's an actual sample:

值

{
    "error":null,
    "result":
        {"ABQz": { // <-- As you can see, this is NOT a class name.
           "from_email" : "from@email.com",
           "created_on" : "2010-10-15 12:40:00",
           "name"       : "test_new_subscribers",
           "from_name"  : "John Smith",
           "reply_to_email": "from@email.com"
        }
    }
}

现在，我不知道这是什么价值将是，我难倒。我想包括值作为广告系列对象的ID。

Now that I don't know what that value is going to be, I'm stumped. I'd like to include that value as an ID for the Campaign object.

答

我看到你的榜样三个对象

I see three objects from your example.

Class CampaignId {

    String name ;
    String from_Name ;
    String from_Email ;
    \\ etc
}

Class Result {
   CampaignId campaignId  ;
}


Class RpcResponse {
   String error ;
   Result result ;
}



你需要数据成员属性？

Do you need DataMember attributes?

在F＃的好文章，我用学习时JSON序列：
的 http://blogs.msdn.com/b/jomo_fisher/archive/2010/03/06/neat-sample-f-and-freebase.aspx

a good article in F# that I used when learning JSON serialization: http://blogs.msdn.com/b/jomo_fisher/archive/2010/03/06/neat-sample-f-and-freebase.aspx

下面的响应发展，你可能想引入一些仿制药：

Developing on the response below, you may want to introduce some generics:

Class CampaignId {

    String name ;
    String from_Name ;
    String from_Email ;
    \\ etc
}

Class Result<T> {
   <T> data ;
}


Class RpcResponse<T> {
   String error ;
   Result<T> result ;
}

和intialize以

And intialize the serializer with

JavaScriptSerializer jss = new JavaScriptSerializer(); 
var r = jss.Deserialize<RpcResponse<CampaignId>>(response_string);
