Question

我想从我在XDocument中编写的WCF客户端捕获肥皂信封消息。因此，我编写了自己的客户消息检查器：

public class MessageInspector : IClientMessageInspector
{
    public object BeforeSendRequest(ref Message request, IClientChannel channel)
    {
        var xDocument = new XDocument();

        using (var stream = new MemoryStream())
        {
            using (var writer = XmlWriter.Create(stream))
            {
                request.WriteMessage(writer);
                writer.Flush();
                stream.Position = 0;

                xDocument.Save(stream);
            }
        }

        return request;
    }

    public void AfterReceiveReply(ref Message reply, object correlationState)
    {
    }
}

端点行为：

public class InspectorBehavior : IEndpointBehavior
{
    public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
    {
        clientRuntime.MessageInspectors.Add(new MessageInspector());
    }
}

我已与客户建立联系：

client.Endpoint.Behaviors.Add(new InspectorBehavior());

我的问题是，当我发送消息时，我收到来自xDocument.Save（stream）的异常。它说：

状态为Document的令牌EndDocument将导致无效的XML文档。

（对我而言）SOAP信封看起来像有效的XML：

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Header>
        <Action s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">http://localhost:8080/kestrel/AirService</Action>
        <h:SessionContext xmlns="http://www.mywebsite.com/soa/common/security/SessionContext_v1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:h="http://www.mywebsite.com/soa/common/security/SessionContext_v1" />
    </s:Header>
    <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
         <MyMessage Foo="bar" xmlns="http://www.mywebsite.com/schema/air_v46_0">
         </MyMessage>
    </s:Body>
 </s:Envelope>

那我为什么会收到此错误，如何预防呢？
