JSON.NET無法反序列包裹收集

Question

我有一個包裹列表，看起來像這樣：

[Serializable] 
public class OrderManager : IEnumerable<Order> 
{ 
    public OrderManager() 
    { } 

    private List<Order> orders = new List<Order>(); 

    public void AddOrder(Order order) 
    { 
     orders.Add(order); 
    } 

    public IEnumerator<Order> GetEnumerator() 
    { 
     return orders.GetEnumerator(); 
    } 

    System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator() 
    { 
     return orders.GetEnumerator(); 
    } 
} 

包括我這樣的在客戶類中的字段實例：

[Serializable] 
public class Customer 
{ 
    public Customer() 
    { } 

    private OrderManager _orders 
     = new OrderManager(); 
    public OrderManager Orders 
    { 
     get { return _orders; } 
     set { _orders = value; } 
    } 
} 

我創建JSON.NET串行這樣的：

private JsonSerializer GetSerializer() 
{ 
    var serializer = new JsonSerializer(); 

    // on or off the type name handling doesn't help 
    //serializer.TypeNameHandling = TypeNameHandling.All; 

    var contractResolver = new DefaultContractResolver(true); 
    contractResolver.IgnoreSerializableAttribute = false; 
    contractResolver.IgnoreSerializableInterface = false; 

    serializer.ContractResolver = contractResolver; 

    serializer.PreserveReferencesHandling = PreserveReferencesHandling.All; 
    serializer.ReferenceLoopHandling = ReferenceLoopHandling.Ignore; 

    return serializer;   
} 

客戶對象的序列工作，但反序列化過程出現錯誤：

Error setting value to '_orders' on 'Tests.SerializationTests+Customer'.

隨着TypeNameHandling設置爲我得到這樣的：

Type specified in JSON 'Tests.SerializationTests+Order[], Tests, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not compatible with 'Tests.SerializationTests+OrderManager, Tests, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. Path '_orders.$type', line 1, position 232. 

任何想法如何讓Json.NET發揮好與包裹清單？

Answer 1

我猜你需要實現ICollection<Order>

public class OrderManager : IEnumerable<Order>,ICollection<Order> 

-

[Serializable] 
public class OrderManager : IEnumerable<Order>,ICollection<Order> 
{ 
    public OrderManager() 
    { } 

    private List<Order> orders = new List<Order>(); 

    public Order this[int i] 
    { 
     set { AddOrder(value); } 
     get { return orders[i]; } 
    } 

    public void AddOrder(Order order) 
    { 
     orders.Add(order); 
    } 

    public IEnumerator<Order> GetEnumerator() 
    { 
     return orders.GetEnumerator(); 
    } 

    System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator() 
    { 
     return orders.GetEnumerator(); 
    } 

    public void Add(Order item) 
    { 
     AddOrder(item); 
    } 

    public void Clear() 
    { 
     orders.Clear(); 
    } 

    public bool Contains(Order item) 
    { 
     return orders.Contains(item); 
    } 

    public void CopyTo(Order[] array, int arrayIndex) 
    { 
     throw new NotImplementedException(); 
    } 

    public int Count 
    { 
     get { return orders.Count; } 
    } 

    public bool IsReadOnly 
    { 
     get { return false; } 
    } 

    public bool Remove(Order item) 
    { 
     return orders.Remove(item); 
    } 
} 

Answer 2

請嘗試以下兩種情況之一：

讓周圍的名單的包裝集合類稱爲OrderCollection：

[Serializable]/[DataContract] 
public OrderCollection : List<Order> { ... } 

或嘗試打開LIST到一個數組。

讓我們知道如何工作。

我不確定序列化與IEnumerable一起工作，你可以用List來試試它嗎？

[Serializable] 
public class OrderManager : List<Order>
