无法反序列化当前的JSON对象多个对象

我有，当我取回然而数据的单个条目deserialises精细数据，无法反序列化当前的JSON对象多个对象

无法反序列化当前的JSON对象（例如{“名”：“值” }）成型 'System.Collections.Generic.List`1 [Purchaseorderline]' 因为类型需要JSON阵列（例如[1,2,3]），以正确地反序列化。

这是检索订单和的OrderItems，我可以做一个单一的命令（通过请求一个订单号），然而，当我得到的所有订单，它的错误，我已经完成了标准转换成JSON对象，以确保我的课是正确的，什么也看不见林应适用作为数组上我的课就干脆把它变成类型RootObject的名单..

这里是我的代码：

 { 
       // ... Read the string. 
       var result1 = await content.ReadAsStringAsync(); 
       List<Rootobject> POOrders = new List<Rootobject>(); 
       Rootobject test = JsonConvert.DeserializeObject<Rootobject>(result1); 
       POOrders.Add(test); 
       POOrders = JsonConvert.DeserializeObject<List<Rootobject>>(result1); 
      }

看来你的JSON格式不正确。
的Data元件应该是一个阵列，而不是一个对象。

我不能作为其从供应商API调用改变JSON的需要..？我改变了我的类只是一个对象数组[JsonProperty（“Data”）] public object [] Data {get;组; }但没有快乐我害怕， –

你得到的错误是因为你试图将你的JSON字符串反序列化为一个RootObject而不是Rootobject本身。

而且通过复制JSON字符串（完整的），并通过编辑粘贴>粘贴>粘贴JSON作为在Visual Studio类生成的类。

这里是Rootobject：

public class Rootobject 
{ 
    public int TotalItems { get; set; } 
    public Paginginfo PagingInfo { get; set; } 
    public int TotalPages { get; set; } 
    public Datum[] Data { get; set; } 
} 

public class Paginginfo 
{ 
    public int PageSize { get; set; } 
    public int Page { get; set; } 
} 

public class Datum 
{ 
    public int PurchaseOrderID { get; set; } 
    public string PurchaseOrderGuid { get; set; } 
    public User User { get; set; } 
    public string PurchaseOrderReference { get; set; } 
    public DateTime DateRaised { get; set; } 
    public Supplier Supplier { get; set; } 
    public Warehouse Warehouse { get; set; } 
    public DateTime DateDue { get; set; } 
    public string PurchaseOrderStatus { get; set; } 
    public float DeliveryCost { get; set; } 
    public float Subtotal { get; set; } 
    public float TotalVat { get; set; } 
    public float Total { get; set; } 
    public Currency Currency { get; set; } 
    public DateTime DateSent { get; set; } 
    public Purchaseorderline[] PurchaseOrderLines { get; set; } 
} 

public class User 
{ 
    public int UserID { get; set; } 
    public string UserName { get; set; } 
} 

public class Supplier 
{ 
    public int SupplierID { get; set; } 
    public string Name { get; set; } 
} 

public class Warehouse 
{ 
    public string WarehouseName { get; set; } 
    public string WarehouseGuid { get; set; } 
    public int WarehouseID { get; set; } 
} 

public class Currency 
{ 
    public int CurrencyID { get; set; } 
    public string CurrencyCode { get; set; } 
    public string CurrencyName { get; set; } 
} 

public class Purchaseorderline 
{ 
    public int PurchaseOrderLineID { get; set; } 
    public string ProductSKU { get; set; } 
    public int QtyOrdered { get; set; } 
    public int QtyReceived { get; set; } 
    public string PurchaseOrderDetailsStatus { get; set; } 
    public float SinglePrice { get; set; } 
    public float LineVat { get; set; } 
    public float LineTotal { get; set; } 
    public int DeliveryStatusID { get; set; } 
    public float QtyWrittenOff { get; set; } 
    public int CartonQty { get; set; } 
    public int AddedByUserID { get; set; } 
    public int TotalUnitsOrdered { get; set; } 
    public int TotalUnitsReceived { get; set; } 
    public int TotalUnitsWrittenOff { get; set; } 
    public string LineNotes { get; set; } 
}

但是，如果你的JSON字符串包含Rootobjects数组，这样的：

[{RawData1},{RawData2},{RawData3}]

，那么你可以按如下反序列化：

var test = JsonConvert.DeserializeObject<List<Rootobject>>(json);

我收集，因为我可以包含一个单一的RootObject的列表，Im努力让它做的工作，当有多个相同的对象在Json ..这就是错误的地方，我已经在一个示例API（Telerik soap测试API模拟器）上完成了，并且工作正常..但是我真的很难将Json中的数据放到列表中...？ –

我刚刚用数组测试了我的代码。它工作正常。你是如何创建你的课程的？ – Mahdi

我刚刚复制了原始数据到剪贴板，创建了一个类，粘贴特殊并粘贴Json作为类...然后把JsonProperty放在每一个... –

睡在它...它是类似于你的答案是马赫迪三江源，我到deserialise的原料，然后通过deserialised对象的foreach将其添加到列表，

Rootobject test = JsonConvert.DeserializeObject<Rootobject>(result1); 
       foreach(Rootobject items in test.Data) 
       { 
        POOrders.Add(items); 
       }
