c# - 为什么 JsonConvert.DeserializeObject 不起作用？

Question

我有一个来自网络服务的结果，字符串结果是:

{"status":"success","data":{"address":"aa@aa.aa","unconfirmed":[{"tx":"cb2f252078d933f63d9cef52bee8857427d70c1142f41f10567cfad7ef1d2dcb","time_utc":"2015-03-31T19:05:09Z","amount":0.1,"n":0},{"tx":"a34fc5b8b3c29c7046ca8acaedd39280f81597a853f30825856e2f46e498c478","time_utc":"2015-03-31T19:05:01Z","amount":0.1,"n":0}]},"code":200,"message":""}

我正在调用 JsonConvert.DeserializeObject:

UTByAddressessResponse 数据 = Serializer.Deserialize(result);

public static T Deserialize<T>(string json)
{
    return JsonConvert.DeserializeObject<T>(json);
}

public class UTByAddressessResponse
{
    public string status { get; set; }
    public UnconfirmedAddressInfo[] data { get; set; }
    public string code { get; set; }
    public string message { get; set; }
}

public class UnconfirmedAddressInfo
{
    public string address { get; set; }
    public List<UT> unconfirmed { get; set; }
}

public class UT
{
    public string tx { get; set; }
    public DateTime time_utc { get; set; }
    public float amount { get; set; }
    public long n { get; set; }
}

但不断收到错误:

Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'Dice.Common.Objects.UnconfirmedAddressInfo[]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.

为什么 ？

Answer 1

将您的 json 粘贴到 http://json2csharp.com/ 它将创建以下类

public class Unconfirmed
{
    public string tx { get; set; }
    public string time_utc { get; set; }
    public double amount { get; set; }
    public int n { get; set; }
}

public class Data
{
    public string address { get; set; }
    public List<Unconfirmed> unconfirmed { get; set; }
}

public class RootObject
{
    public string status { get; set; }
    public Data data { get; set; }
    public int code { get; set; }
    public string message { get; set; }
}

现在你可以反序列化为

var obj = JsonConvert.DeserializeObject<RootObject>(json_string);

PS:你可以重命名你的类名，但是如果你想重命名属性，你应该使用 JsonProperty 属性。
