WCF CollectionDataContract未使用ItemName

我有一个本地托管的WCF服务，我尝试使用WCF的CollectionDataContract

服务合同如下所示：

[OperationContract]
GetSalesDeliveryNotesResponse GetSalesDeliveryNotes(GetSalesDeliveryNotesRequest request);

[DataMember]
public SerialList Serials { get; set; }

[CollectionDataContract(ItemName = "Serial")]
public class SerialList : List<string> {
    public SerialList() : base() { }

    public SerialList(List<string> l) : base() {
        AddRange(l);
    }
}

Serials = new GetSalesDeliveryNotesResponse.DeliveryNote.Order.Orderline.SerialList(
    (from s in r.Descendants("Serial") 
    select s.Value).ToList()
)

<Serials>
    <string>123789456</string>
</Serials>

<Serials>
    <Serial>123789456</Serial>
</Serials>

GetSalesDeliveryNotesResponse类有一个属性Serials，如下所示：

[OperationContract]
GetSalesDeliveryNotesResponse GetSalesDeliveryNotes(GetSalesDeliveryNotesRequest request);

[DataMember]
public SerialList Serials { get; set; }

[CollectionDataContract(ItemName = "Serial")]
public class SerialList : List<string> {
    public SerialList() : base() { }

    public SerialList(List<string> l) : base() {
        AddRange(l);
    }
}

Serials = new GetSalesDeliveryNotesResponse.DeliveryNote.Order.Orderline.SerialList(
    (from s in r.Descendants("Serial") 
    select s.Value).ToList()
)

<Serials>
    <string>123789456</string>
</Serials>

<Serials>
    <Serial>123789456</Serial>
</Serials>

SerialList类是GetSalesDeliveryNotesResponse的内部类，如下所示：

[OperationContract]
GetSalesDeliveryNotesResponse GetSalesDeliveryNotes(GetSalesDeliveryNotesRequest request);

[DataMember]
public SerialList Serials { get; set; }

[CollectionDataContract(ItemName = "Serial")]
public class SerialList : List<string> {
    public SerialList() : base() { }

    public SerialList(List<string> l) : base() {
        AddRange(l);
    }
}

Serials = new GetSalesDeliveryNotesResponse.DeliveryNote.Order.Orderline.SerialList(
    (from s in r.Descendants("Serial") 
    select s.Value).ToList()
)

<Serials>
    <string>123789456</string>
</Serials>

<Serials>
    <Serial>123789456</Serial>
</Serials>

其中r是服务连接到Oracle数据库的元素的集合，执行一个存储过程，该存储过程返回一个XML，我的服务必须将该XML序列化到客户端

请注意，DeliveryNote、Order和Orderline也是Response对象的内部类，但为了简洁起见，它们被省略了，还有一些其他属性

我遇到的问题是，我的响应客户端中的Serials对象如下所示：

[OperationContract]
GetSalesDeliveryNotesResponse GetSalesDeliveryNotes(GetSalesDeliveryNotesRequest request);

[DataMember]
public SerialList Serials { get; set; }

[CollectionDataContract(ItemName = "Serial")]
public class SerialList : List<string> {
    public SerialList() : base() { }

    public SerialList(List<string> l) : base() {
        AddRange(l);
    }
}

Serials = new GetSalesDeliveryNotesResponse.DeliveryNote.Order.Orderline.SerialList(
    (from s in r.Descendants("Serial") 
    select s.Value).ToList()
)

<Serials>
    <string>123789456</string>
</Serials>

<Serials>
    <Serial>123789456</Serial>
</Serials>

当我期望它看起来像这样时：

[OperationContract]
GetSalesDeliveryNotesResponse GetSalesDeliveryNotes(GetSalesDeliveryNotesRequest request);

[DataMember]
public SerialList Serials { get; set; }

[CollectionDataContract(ItemName = "Serial")]
public class SerialList : List<string> {
    public SerialList() : base() { }

    public SerialList(List<string> l) : base() {
        AddRange(l);
    }
}

Serials = new GetSalesDeliveryNotesResponse.DeliveryNote.Order.Orderline.SerialList(
    (from s in r.Descendants("Serial") 
    select s.Value).ToList()
)

<Serials>
    <string>123789456</string>
</Serials>

<Serials>
    <Serial>123789456</Serial>
</Serials>

我错过了什么

//编辑： 更多信息： 该服务的客户端实现对SerialList类具有以下特性：

[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "4.0.0.0")]
[System.Runtime.Serialization.CollectionDataContractAttribute(Name="GetSalesDeliveryNotesResponse.DeliveryNote.Order.Orderline.SerialList", Namespace="http://schemas.datacontract.org/2004/07/<my_namespace>/DeliveryNoteService.Contract.Response", ItemName="Serial")]
[System.SerializableAttribute()]
public class SerialList : System.Collections.Generic.List<string> { }

显然我的服务是正确的。使用WCFTestClient给出了正确的响应。因此，我自己的测试代码出现了问题。

您确定您这边没有问题吗？因为我已经测试了这段代码，并且得到了正确的xml输出。试试WCFTestClient。@cybermaxs：现在我觉得自己很愚蠢。。。WCFTestClient给出了正确的响应。谢谢你的提示！
