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":""}

我打电话给 JsonConvert.DeserializeObject:

UTByAddressessResponse 数据 = Serializer.Deserialize（结果）；

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; }
}

但是一直报错:

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 classes

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：您可以重命名您的 class 名称，但如果您想重命名属性，您应该使用 JsonProperty 属性。

Answer 2

问题是

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

应该是

public class UTByAddressessResponse
{
    public string status { get; set; }
    public UnconfirmedAddressInfo data { get; set; } // not array
    public string code { get; set; }
    public string message { get; set; }
}

为什么 JsonConvert.DeserializeObject 不起作用？
