使用Json.NET使用数组数组反序列化json字符串

string json = @"{ 'symbol':'XX', 'column_names":["Date","Open","High","Low","Close","Volume"], 'data':[ ['2014-01-02',25.78,25.82,25.47,25.79,31843697.0], ['2013-12-31',25.81,26.04,25.77,25.96,22809682.0]]}"; public class DailyData { public string symbol { get; set; } public List data { get; set; } } public class OneDay { public DateTime date { get; set; } public double open { get; set; } public double high { get; set; } public double low { get; set; } public double close { get; set; } public double volume { get; set; } } DailyData dd = JsonConvert.DeserializeObject(json); 

这是我的json字符串和类我试图用Json.net反序列化它。 如果我更改公共List data { get; set; } List data { get; set; } public List data { get; set; } public List data { get; set; } public List data { get; set; } 。 但在这种情况下，我还需要做更多的工作。 是否有一个简洁的解决方案可以一次性反序列化它？

Answer 1

是的，您必须使用JsonConverter类来告诉反序列化器如何将值数组映射到OneDay类。

例：

 void Main() { string json = @"{ 'symbol':'XX', 'column_names':['Date','Open','High','Low','Close','Volume'], 'data':[ ['2014-01-02',25.78,25.82,25.47,25.79,31843697.0], ['2013-12-31',25.81,26.04,25.77,25.96,22809682.0] ] }"; DailyData dd = JsonConvert.DeserializeObject(json); dd.Dump(); } class OneDayJsonConverter : JsonConverter { public override bool CanConvert(Type objectType) { throw new NotImplementedException(); } public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer) { OneDay obj = new OneDay(); obj.date = reader.ReadAsDateTime() ?? DateTime.MinValue; obj.open = (double)(reader.ReadAsDecimal() ?? 0); obj.high = (double)(reader.ReadAsDecimal()?? 0); obj.low = (double)(reader.ReadAsDecimal() ?? 0); obj.close = (double)(reader.ReadAsDecimal() ?? 0); obj.volume = (double)(reader.ReadAsDecimal() ?? 0); reader.Read(); return obj; } public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer) { throw new NotImplementedException(); } } public class DailyData { public string symbol { get; set; } public List data { get; set; } } [JsonConverter(typeof(OneDayJsonConverter))] public class OneDay { public DateTime date { get; set; } public double open { get; set; } public double high { get; set; } public double low { get; set; } public double close { get; set; } public double volume { get; set; } } 

结果：
