[英]C# Complex Json Deserialization
I was not able to create a working solution with the existing answered questions. 我无法使用现有的已回答问题创建一个可行的解决方案。
I am successfully using the following c# class 我成功使用以下c#类
public class country
{
public string country_id;
public string country_name;
}
with the following code. 使用以下代码。 The result is a countries list
结果是一个国家列表
List<country> countries = new List<country>();
var streamTask = client.GetStreamAsync("https://xxx");
var serializer = new DataContractJsonSerializer(typeof(List<country>));
countries = serializer.ReadObject(await streamTask) as List<country>;
BUT : now I changed the API and I get a result where I have no clue how to create the class to use the same code. 但是 :现在我更改了API,但得到的结果是我不知道如何创建使用相同代码的类。
This is the result of the API call: 这是API调用的结果:
{
"api":{
"results": 2
"countries":{
"1":"Austria"
"2":"Germany"
}
}
}
It is a nested object and "countries" does not even have property names. 它是一个嵌套对象,“国家”甚至没有属性名称。
How do I deserialize this result? 如何反序列化此结果?
To start with you will need to change your data contracts: 首先,您需要更改数据合同:
public class apiResults
{
public int results;
public countries countries;
}
public class apiResponse
{
public apiResults api;
}
[DataContract]
public class countries
{
[DataMember(Name="1")]
public string Country1 {get; set;}
}
and then use it as before: 然后像以前一样使用它:
var serializer = new DataContractJsonSerializer(typeof(apiResponse));
var result = serializer.ReadObject(stream) as apiResponse;
Console.WriteLine(result.api.countries.Country1);
The problem here is that you hardcoding the number of available countries. 这里的问题是您对可用国家/地区的数量进行了硬编码。 Better way will be to deserialize your new countries class into array.
更好的方法是将您的新国家/地区分类反序列化。
If you can use NewtonsoftJson - the solution is much easier: 如果您可以使用NewtonsoftJson-解决方案将更加容易:
public class apiResults
{
public int results;
public Dictionary<int, string> countries { get; set; }
}
public class apiResponse
{
public apiResults api;
}
and usage: 和用法:
var result = JsonConvert.DeserializeObject<apiResponse>(responseAsString);
Console.WriteLine(result.api.countries[1]);
