我正在尝试将JSON反序列化为对象“MarginBalance”。当我尝试反序列化这个JSON:
{"totalValue":"0.00091979","pl":"0.00000000","lendingFees":"0.00000000","netValue":"0.00091979","totalBorrowedValue":"0.00000000","currentMargin":"1.00000000"}
到这个对象:
public class MarginBalance : IMarginBalance
{
[JsonProperty("totalValue")]
public double TotalValue { get; set; }
[JsonProperty("pl")]
public double PL { get; set; }
[JsonProperty("lendingFees")]
public double LendingFees { get; set; }
[JsonProperty("netValue")]
public double NetValue { get; set; }
[JsonProperty("totalBorrowedValue")]
public double TotalBorrowedValue { get; set; }
[JsonProperty("currentMargin")]
public double CurrentMargin { get; set; }
}
实现此接口:
public interface IMarginBalance
{
double TotalValue { get; }
double PL { get; }
double LendingFees { get; }
double NetValue { get; }
double TotalBorrowedValue { get; }
double CurrentMargin { get; }
}
它返回null。这是我的反序列化代码:
var postData = new Dictionary<string, object>();
var data = PostData<IDictionary<string, MarginBalance>>("returnMarginAccountSummary", postData);
if (data != null)
{
// never reaches here
var returnData = new Dictionary<string, IMarginBalance>();
foreach (string key in data.Keys)
{
returnData.Add(key, data[key]);
}
return returnData;
}
[MethodImpl(MethodImplOptions.AggressiveInlining)]
private T PostData<T>(string command, Dictionary<string, object> postData)
{
return ApiWebClient.PostData<T>(command, postData);
}
public T PostData<T>(string command, Dictionary<string, object> postData)
{
postData.Add("command", command);
postData.Add("nonce", Helper.GetCurrentHttpPostNonce());
var jsonString = PostString(Helper.ApiUrlHttpsRelativeTrading, postData.ToHttpPostString());
var output = JsonSerializer.DeserializeObject<T>(jsonString);
return output;
}
希望有人可以解决这个问题!我一整天都在努力......提前谢谢。

Json中的数字被撇号包围,这意味着它们是字符串,而不是数字。您可以尝试从Json字符串中的数字中删除撇号,或者在对象中将字段类型从double更改为字符串。
JsonProperty
中使用的MarginBalance
属性属于Newtonsoft.Json.Serialization
命名空间。要反序列化对象,您应该使用JsonConvert.DeserializeObject<MarginBalance>(jsonString)
