Question

有没有办法将复杂对象列表反序列化为已知类型列表： EX：

 public class Employee
    {
        public string EmployeeNumber { get; set; }
        public string AccountName { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string PreferredName { get; set; }
        public string Title { get; set; }
    }

这是我想要反序列化的对象。

这就是我的尝试方式：

var x = JsonConvert.DeserializeObject<List<Dictionary<string, IList<Employee>>>>(_content);
var x = JsonConvert.DeserializeObject<List<Dictionary<string, Employee>>>(_content);
var x = JsonConvert.DeserializeObject<List<Dictionary<string, Employee[]>>>(_content);

但是我得到了这个例外

 "ExceptionMessage": "Error converting value 37326 to type 'System.Collections.Generic.IList`1[Ubisoft.ECM.Events.Business.Providers.EmployeeProvider.Empoyee]'. Path '[0].EmployeeNumber', line 1, position 24.",

内部异常：

"InnerException": {
    "Message": "An error has occurred.",
    "ExceptionMessage": "Could not cast or convert from System.Int64 to System.Collections.Generic.IList`1[Ubisoft.ECM.Events.Business.Providers.EmployeeProvider.Employee].",
    "ExceptionType": "System.ArgumentException",
    "StackTrace": "   at Newtonsoft.Json.Utilities.ConvertUtils.EnsureTypeAssignable(Object value, Type initialType, Type targetType)\r\n   at Newtonsoft.Json.Utilities.ConvertUtils.ConvertOrCast(Object initialValue, CultureInfo culture, Type targetType)\r\n   at Newtonsoft.Json.Serialization.JsonSerializerInternalReader.EnsureType(JsonReader reader, Object value, CultureInfo culture, JsonContract contract, Type targetType)"
  }

谢谢。

所以为了反序列化到List我必须引用System.Web.Script.Serialization。

创建正确的对象。

 public class MyType
    {
        public string Prop1Name{ get; set; }
        public string Prop2Name{ get; set; }
        public string PropNName{ get; set; }
    }

并使用命名空间中的JavaScriptSerializer。

List<MyType> x = new JavaScriptSerializer().Deserialize<List<MyType>>(_content);
