我在代码中调用此Web服务，我希望看到XML，但我找不到暴露它的属性。

我认为你的意思是你希望在客户端看到XML，而不是在服务器上跟踪它。在这种情况下，您的答案就在我上面提到的问题中，也在How to Inspect or Modify Messages on the Client处。但是，由于该文章的.NET 4版本缺少其C＃，并且.NET 3.5示例中存在一些混淆（如果不是错误），此处它会针对您的目的进行扩展。
拦截消息using System.ServiceModel.Dispatcher;
public class MyMessageInspector : IClientMessageInspector
{ }
该界面中的方法BeforeSendRequest和AfterReceiveReply可让您访问请求和回复。要使用检查器，您需要将其添加到IEndpointBehavior：
using System.ServiceModel.Description;
public class InspectorBehavior : IEndpointBehavior
{
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
clientRuntime.MessageInspectors.Add(new MyMessageInspector());
}
}
您可以将该接口的其他方法保留为空实现，除非您也想使用它们的功能。阅读操作方法以获取更多详细信息。
实例化客户端后，将行为添加到端点。使用示例WCF项目中的默认名称：
ServiceReference1.Service1Client client = new ServiceReference1.Service1Client();
client.Endpoint.Behaviors.Add(new InspectorBehavior());
client.GetData(123);
在MyMessageInspector.BeforeSendRequest()中设置断点;重载request.ToString()以显示XML。
如果您要操纵消息，则必须处理消息的副本。有关详细信息，请参阅Using the Message Class。

答案 2 :(得分：6)
OperationContext.Current.RequestContext.RequestMessage
在处理请求期间，此上下文是可访问的服务器端。 这不适用于单向操作
答案 3 :(得分：6)
我们只需将请求消息跟踪为。
OperationContext context = OperationContext.Current;
if (context != null && context.RequestContext != null)
{
Message msg = context.RequestContext.RequestMessage;
string reqXML = msg.ToString();
}
答案 4 :(得分：2)
我只想将此添加到金伯利的答案中。也许它可以节省一些时间并避免编译错误，因为没有实现IEndpointBehaviour接口所需的所有方法。

我在ASP.NET兼容模式下使用以下解决方案进行IIS托管。致Rodney Viana的MSDN blog。
在appSettings：
下的web.config中添加以下内容<add key="LogPath" value="C:\\logpath" />
<add key="LogRequestResponse" value="true" />

它应该在LogPath文件夹中创建带有请求和响应XML的日志文件。

还有另一种方法可以查看XML SOAP - custom MessageEncoder。与IClientMessageInspector的主要区别在于它在较低级别上工作，因此它捕获原始字节内容，包括任何格式错误的xml。
为了使用此方法实现跟踪，您需要将标准textMessageEncoding与custom message encoder包装为新binding element，并将该自定义绑定应用于config中的端点。
你也可以看看我在项目中是如何做到的 - wrapping textMessageEncoding，记录encoder，自定义绑定element和config。
