JSON到DataTable

我正在尝试将JSON文本序列化为DataTable，如下所示。

List<Dictionary> list = JsonConvert.DeserializeObject<List<Dictionary>>(jsonText); DataTable dTable; dTable = (from p in list select p).CopyToDataTable(); 

我收到以下错误。 我如何解决它？

错误：

 Cannot deserialize JSON object into type 'System.Collections.Generic.List`1[System.Collections.Generic.Dictionary`2 [System.String,System.String]]'. 

Answer 1

这对我有用：

 using Newtonsoft.Json; string json = "[{"clientID":"1788","projectID":"19"},{"clientID":"1789","projectID":"24"},{"clientID":"1790","projectID":"24"},{"clientID":"1790","projectID":"23"},{"clientID":"1790","projectID":"21"}]"; DataTable tester = (DataTable) JsonConvert.DeserializeObject(json, (typeof(DataTable))); 

Answer 2

 public object Deserialize(string jsonText, Type valueType) { try { Newtonsoft.Json.JsonSerializer json = new Newtonsoft.Json.JsonSerializer(); json.NullValueHandling = Newtonsoft.Json.NullValueHandling.Ignore; json.ObjectCreationHandling = Newtonsoft.Json.ObjectCreationHandling.Replace; json.MissingMemberHandling = Newtonsoft.Json.MissingMemberHandling.Ignore; json.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore; StringReader sr = new StringReader(jsonText); Newtonsoft.Json.JsonTextReader reader = new JsonTextReader(sr); object result = json.Deserialize(reader, valueType); reader.Close(); return result; } catch (Exception ex) { throw ex; } }
