JsonString反序列化错误

Question

我想反序列化我JsonString

string JsonString= "{\"RequestId\":1308,\"Warning\":[\"WARNING_NoOrdersForCustomer\"],\"Customer\":{\"__type\":\"CustomerOrder:#Data\",\"Email\":\"xyz@yahoo.com\",\"FullName\":\"Anke White\",\"Phone\":\"\",\"Orders\":[]}}" 

这里是我的datacontracts

[DataContract] 
     public class SalesInfo 
     { 
      [DataMember(Name = "RequestId")] 
      public string RequestId { get; set; } 

      [DataMember(Name = "Warning")] 
      public string[] Warning { get; set; } 

      [DataMember(Name = "Customer")] 
      public Customer CustomerData { get; set; } 

     } 

[DataContract] 
    public class Customer 
     { 
      [DataMember(Name = "Email")] 
      public string Email { get; set; } 

      [DataMember(Name = "FullName")] 
      public string FullName { get; set; } 

      [DataMember(Name = "Phone")] 
      public string Phone { get; set; } 

      [DataMember(Name = "Orders")] 
      public string[] Orders { get; set; } 


     } 

我这个

SalesInfo sales = Deserialize<SalesInfo>(JsonString); 

试过这里是反序列化

private static T Deserialize<T>(string json) 
{ 
    var instance = Activator.CreateInstance<T>(); 
    using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(json))) 
    { 
     var serializer = new DataContractJsonSerializer(instance.GetType()); 
     return (T)serializer.ReadObject(ms); 
    } 
} 

但我收到错误消息

Element ':Customer' contains data from a type that maps to the name 'http://schemas.datacontract.org/2004/07/Data:CustomerOrder'. The deserializer has no knowledge of any type that maps to this name. Consider using a DataContractResolver or add the type corresponding to 'CustomerOrder' to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding it to the list of known types passed to DataContractSerializer. 

请帮我解决这个错误和反序列化JsonString

Answer 1

因为你JsonString是不正确的：

\ “客户\”：{\“__类型\“：\”CustomerOrder：#Data \“，\”Em ...

并且没有关于CustomerOrder类型的任何信息。

在你的情况下，右侧JsonString是：

{\ “请求ID \”：1308，\ “警告\”：\ “WARNING_NoOrdersForCustomer \”]，\ “客户\”：{\“电子邮件\“：\”xyz@yahoo.com \“，\”FullName \“：\”Anke White \“，\”Phone \“：\”\“，\”Orders \“：[]}}

Answer 2

好像你正在使用专有的MS Ajax JSON格式，插入这些与其他任何东西不兼容的“__type”东西。

因此请检查解决方案的序列化部分。
