如何将IXmlSerializable类的数组作为参数传递给WCF？

Question

我有两个类，一个实现Func，另一个具有IXmlSerializable属性：

DataContract

然后我有服务接口

public class Foo : IXmlSerializable
{
    public XmlSchema GetSchema()
    {
        return null;
    }

    public void ReadXml(XmlReader reader)
    {
        reader.MoveToContent();
        XElement element = (XElement)XNode.ReadFrom(reader);

        if (element.Element("Foo") != null)
            element = element.Element("Foo");

        Property = Convert.ToInt32(element.Element("Property").Value);
    }

    public void WriteXml(XmlWriter writer)
    {
        var element = new XElement("Foo");
        element.Add(new XElement("Property", Property));

        element.WriteTo(writer);
    }

    public int Property { get; set; }
}

[DataContract]
public class Bar
{
    [DataMember]
    public int Property { get; set; }
}

其实施方式为：

[ServiceContract]
public interface IFooBarService
{
    [OperationContract]
    void TestFoo(Foo toTest);

    [OperationContract]
    void TestListFoo(Foo[] toTest);

    [OperationContract]
    void TestBar(Bar toTest);

    [OperationContract]
    void TestListBar(Bar[] toTest);
}

SOAP UI生成了调用服务所需的xml。一切正常，除了调用public class FooBarService : IFooBarService { public void TestFoo(Foo toTest) { var a = toTest.Property; } public void TestListFoo(Foo[] toTest) { foreach (var item in toTest) { var x = item.Property; } } public void TestBar(Bar toTest) { var a = toTest.Property; } public void TestListBar(Bar[] toTest) { foreach (var item in toTest) { var x = item.Property; } } } ，我收到一个空数组

TestListFoo

我错过了什么？有可能实现我的需要吗？ 如果没有，我如何将<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/" xmlns:com="http://schemas.datacontract.org/2004/07/Com.Panotec.Remote.Core.WebService" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <soapenv:Header/> <soapenv:Body> <tem:TestListFoo> <tem:toTest> <Foo> <Property>1</Property> </Foo> <Foo> <Property>1</Property> </Foo> <Foo> <Property>1</Property> </Foo> <Foo> <Property>1</Property> </Foo> </tem:toTest> </tem:TestListFoo> </soapenv:Body> </soapenv:Envelope> 属性添加到实现DataContract的类？
