c# - JSON解析C#无名称变量

Question

我正在尝试将 Json 字符串反序列化为一个对象，但我只得到 0 和 null。

这是我的代码:

string result = "[{\"page\":1,\"pages\":1,\"per_page\":\"50\",\"total\":1},[{\"id\":\"BEL\",\"iso2Code\":\"BE\",\"name\":\"Belgium\",\"region\":{ \"id\":\"ECS\",\"value\":\"Europe & Central Asia(all income levels)\"},\"adminregion\":{ \"id\":\"\",\"value\":\"\"},\"incomeLevel\":{ \"id\":\"OEC\",\"value\":\"High income: OECD\"},\"lendingType\":{ \"id\":\"LNX\",\"value\":\"Not classified\"},\"capitalCity\":\"Brussels\",\"longitude\":\"4.36761\",\"latitude\":\"50.8371\"}]]";

var serializer = new DataContractJsonSerializer(typeof(LandRootObject));

var ms = new MemoryStream(Encoding.UTF8.GetBytes(result));

var data = (LandRootObject)serializer.ReadObject(ms);


public class LandRootObject
{
    public int page { get; set; }
    public int pages { get; set; }
    public string per_page { get; set; }
    public int total { get; set; }

    [DataMember]
    public List<Land> land { get; set; }
}

谢谢!

我已经测试了这个方法并且它正在工作。

您的实体类。 (我没有编写所有这些类的代码。它们是使用特殊粘贴生成的代码。)

public class LandRootObject
{
    public int page { get; set; }
    public int pages { get; set; }
    public string per_page { get; set; }
    public int total { get; set; }
}

public class LandBodyObject
{
    public string id { get; set; }
    public string iso2Code { get; set; }
    public string name { get; set; }
    public Region region { get; set; }
    public Adminregion adminregion { get; set; }
    public Incomelevel incomeLevel { get; set; }
    public Lendingtype lendingType { get; set; }
    public string capitalCity { get; set; }
    public string longitude { get; set; }
    public string latitude { get; set; }
}

public class Region
{
    public string id { get; set; }
    public string value { get; set; }
}

public class Adminregion
{
    public string id { get; set; }
    public string value { get; set; }
}

public class Incomelevel
{
    public string id { get; set; }
    public string value { get; set; }
}

public class Lendingtype
{
    public string id { get; set; }
    public string value { get; set; }
}

然后是反序列化方法。你的 Json 有两部分。所以我将它分成 2 部分进行反序列化。

    string result = "[{\"page\":1,\"pages\":1,\"per_page\":\"50\",\"total\":1},[{\"id\":\"BEL\",\"iso2Code\":\"BE\",\"name\":\"Belgium\",\"region\":{ \"id\":\"ECS\",\"value\":\"Europe & Central Asia(all income levels)\"},\"adminregion\":{ \"id\":\"\",\"value\":\"\"},\"incomeLevel\":{ \"id\":\"OEC\",\"value\":\"High income: OECD\"},\"lendingType\":{ \"id\":\"LNX\",\"value\":\"Not classified\"},\"capitalCity\":\"Brussels\",\"longitude\":\"4.36761\",\"latitude\":\"50.8371\"}]]";

    var parts = result.Split(new[] {",["}, StringSplitOptions.None);
    if (parts.Length > 1)
    {
        var header = parts[0].Replace("[", "");
        var jsonHeader = JsonConvert.DeserializeObject<LandRootObject>(header);

        var body = "[" + parts[1].Replace("]]","]");
        var jsonBody = JsonConvert.DeserializeObject<List<LandBodyObject>>(body);
    }
