Question

我无法将JSON字符串反序列化为我写的类。

这是我的课程

class Newsletter
{
public string id;
public string state;
public string html;
public string name;
}


class ApiReply
{
    int success;
    //string value;
    int status;
    string reason;
}


class Newsletterlist : ApiReply
{
    private const string URL = "https://www.newsletter2go.de/de/api/get/newsletters/";
    public string key { private set; get; }
    public  Newsletterlist()
    {

        key = "MYAPIKEY";
        HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(URL);
        httpWebRequest.ContentType = "application/x-www-form-urlencoded";
        httpWebRequest.Method = "POST";
        byte[] data = PostData.get_postData(this);
        httpWebRequest.ContentLength = data.Length;

        using (var stream = httpWebRequest.GetRequestStream())
        {
            stream.Write(data, 0, data.Length);
        }

        var response = (HttpWebResponse)httpWebRequest.GetResponse();

        var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
        dynamic temp = JsonConvert.DeserializeObject(responseString);
    }

    public List<Newsletter> value {private set;get;}


}

我想将JSON返回字符串反序列化为我的对象新闻稿列表，但是在JSON字符串中，有一个JSON数组，我不知道如何将JSON数组反序列化为List Value。

JSON String看起来像这样：

{
success : 0,
value :  [],  <--  Value may contain a JSON Array wich I want to Serialize to List<Newsletter>
status :405,
reason : “Method Not Allowed , POST Required”
}

你需要知道在数组中将返回给你的是什么，如果它只是一个字符串值数组，那么如果它是一个复杂类型则值为List<string>然后创建一个匹配它的对象有一个List<ComplexType>

class ApiReply
{
    int success {get;set}
    List<string> value {get;set;}
    int status {get;set;}
    string reason {get;set;}
}

或复杂类型：

public class SomeType
{
    public string Name {get;set;}
    public int Age {get;set;}
}

class ApiReply
{
    int success {get;set}
    List<SomeType> value {get;set;}
    int status {get;set;}
    string reason {get;set;}
}

这样的JSON看起来像这样：

{
success : 0,
value :  [{name="fred", age=21},{name="paul", age=53}],  <--  Value may contain a JSON Array
status :405,
reason : “Method Not Allowed , POST Required”
}

复杂子数组的示例：JSONConvert.DeserializeObject not handling child array with unnamed array items

反序列化从HTTP响应返回的JSON数组
