I think you meant that you want to see the XML at the client, not trace it at the server. In that case, your answer is in the question I linked above, and also at <a href="http://msdn.microsoft.com/en-us/library/ms733786.aspx" rel="noreferrer">How to Inspect or Modify Messages on the Client</a>. But, since the .NET 4 version of that article is missing its C#, and the .NET 3.5 example has some confusion (if not a bug) in it, here it is expanded for your purpose.

You can intercept the message before it goes out using an <a href="http://msdn.microsoft.com/en-us/library/system.servicemodel.dispatcher.iclientmessageinspector.aspx" rel="noreferrer">IClientMessageInspector</a>:

<pre><code>using System.ServiceModel.Dispatcher;
public class MyMessageInspector : IClientMessageInspector
{ }
</code></pre>

The methods in that interface, <code>BeforeSendRequest</code> and <code>AfterReceiveReply</code>, give you access to the request and reply. To use the inspector, you need to add it to an <a href="http://msdn.microsoft.com/en-us/library/system.servicemodel.description.iendpointbehavior.aspx" rel="noreferrer">IEndpointBehavior</a>:

<pre><code>using System.ServiceModel.Description;
public class InspectorBehavior : IEndpointBehavior
{
 public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
 {
 clientRuntime.MessageInspectors.Add(new MyMessageInspector());
 }
}
</code></pre>

You can leave the other methods of that interface as empty implementations, unless you want to use their functionality, too. Read the how-to for more details.

After you instantiate the client, add the behavior to the endpoint. Using default names from the sample WCF project:

<pre><code>ServiceReference1.Service1Client client = new ServiceReference1.Service1Client();
client.Endpoint.Behaviors.Add(new InspectorBehavior());
client.GetData(123);
</code></pre>

Set a breakpoint in <code>MyMessageInspector.BeforeSendRequest()</code>; <code>request.ToString()</code> is overloaded to show the XML.

If you are going to manipulate the messages at all, you have to work on a copy of the message. See <a href="http://msdn.microsoft.com/en-us/library/ms734675.aspx" rel="noreferrer">Using the Message Class</a> for details.

Thanks to <a href="https://stackoverflow.com/questions/1217374/intercept-messages-in-a-wcf-client/1218139#1218139">Zach Bonham's answer</a> at another question for finding these links.

this context is accesible server side during processing of request.
This doesn`t works for one-way operations

Simply we can trace the request message as.

Message msg = context.RequestContext.RequestMessage;

string reqXML = msg.ToString();

I just wanted to add this to the answer from Kimberly. Maybe it can save some time and avoid compilation errors for not implementing all methods that the IEndpointBehaviour interface requires.

Best regards

blocks|key|949008|text|还有另一种查看XML+SOAP的方法--++custom+MessageEncoder。与IClientMessageInspector的主要区别在于，它工作在较低的级别，因此它捕获原始字节内容，包括任何格式错误的xml。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|949009|为了使用这种方法实现跟踪，您需要将具有custom+message+encoder的标准textMessageEncoding包装为新的binding+element，并将该自定义绑定应用于config中的端点。|949010|你也可以看到我是如何在我的项目中做到这一点的--+wrapping+textMessageEncoding，logging+encoder，custom+binding+element和config。|949011|entityMap|0|LINK|mutability|MUTABLE|url|https://docs.microsoft.com/en-us/dotnet/api/system.servicemodel.channels.messageencoder|1|https://docs.microsoft.com/en-us/dotnet/framework/wcf/samples/custom-message-encoder-custom-text-encoder|2|https://docs.microsoft.com/en-us/dotnet/framework/configure-apps/file-schema/wcf/textmessageencoding|3|https://msdn.microsoft.com/en-us/library/system.servicemodel.channels.textmessageencodingbindingelement%2528v=vs.110%2529.aspx|4|https://docs.microsoft.com/en-us/dotnet/framework/wcf/samples/custom-binding-transport-and-encoding|5|https://github.com/capslocky/WcfSoapLogger/blob/master/src/Library/WcfSoapLogger/EncodingExtension/LoggingBindingElement.cs|6|https://github.com/capslocky/WcfSoapLogger/blob/master/src/Library/WcfSoapLogger/EncodingExtension/LoggingEncoder.cs|7|https://github.com/capslocky/WcfSoapLogger/blob/master/src/Library/WcfSoapLogger/EncodingExtension/LoggingExtensionElement.cs|8|https://github.com/capslocky/WcfSoapLogger/blob/master/src/UsageExamples/ExampleBeta/Client/App.config^0|L|M|0|0|J|M|1|18|J|2|1W|F|3|2N|6|4|0|P|8|5|1Q|7|6|2D|7|7|2L|6|8|0^^$0|@$1|2|3|4|5|6|7|15|8|@]|9|@$A|16|B|17|1|18]]|C|$]]|$1|D|3|E|5|6|7|19|8|@]|9|@$A|1A|B|1B|1|1C]|$A|1D|B|1E|1|1F]|$A|1G|B|1H|1|1I]|$A|1J|B|1K|1|1L]]|C|$]]|$1|F|3|G|5|6|7|1M|8|@]|9|@$A|1N|B|1O|1|1P]|$A|1Q|B|1R|1|1S]|$A|1T|B|1U|1|1V]|$A|1W|B|1X|1|1Y]]|C|$]]|$1|H|3|-4|5|6|7|1Z|8|@]|9|@]|C|$]]]|I|$J|$5|K|L|M|C|$N|O]]|P|$5|K|L|M|C|$N|Q]]|R|$5|K|L|M|C|$N|S]]|T|$5|K|L|M|C|$N|U]]|V|$5|K|L|M|C|$N|W]]|X|$5|K|L|M|C|$N|Y]]|Z|$5|K|L|M|C|$N|10]]|11|$5|K|L|M|C|$N|12]]|13|$5|K|L|M|C|$N|14]]]]

There is an another way to see XML SOAP - <a href="https://docs.microsoft.com/en-us/dotnet/api/system.servicemodel.channels.messageencoder" rel="nofollow noreferrer"> custom MessageEncoder</a>. The main difference from IClientMessageInspector is that it works on lower level, so it captures original byte content including any malformed xml.

In order to implement tracing using this approach you need to wrap a standard <a href="https://docs.microsoft.com/en-us/dotnet/framework/configure-apps/file-schema/wcf/textmessageencoding" rel="nofollow noreferrer">textMessageEncoding</a> with <a href="https://docs.microsoft.com/en-us/dotnet/framework/wcf/samples/custom-message-encoder-custom-text-encoder" rel="nofollow noreferrer">custom message encoder</a> as new <a href="https://msdn.microsoft.com/en-us/library/system.servicemodel.channels.textmessageencodingbindingelement%28v=vs.110%29.aspx" rel="nofollow noreferrer">binding element</a> and apply that custom binding to endpoint in your <a href="https://docs.microsoft.com/en-us/dotnet/framework/wcf/samples/custom-binding-transport-and-encoding" rel="nofollow noreferrer">config</a>.

Also you can see as example how I did it in my project -
<a href="https://github.com/capslocky/WcfSoapLogger/blob/master/src/Library/WcfSoapLogger/EncodingExtension/LoggingBindingElement.cs" rel="nofollow noreferrer">wrapping</a> textMessageEncoding, logging <a href="https://github.com/capslocky/WcfSoapLogger/blob/master/src/Library/WcfSoapLogger/EncodingExtension/LoggingEncoder.cs" rel="nofollow noreferrer">encoder</a>, custom binding <a href="https://github.com/capslocky/WcfSoapLogger/blob/master/src/Library/WcfSoapLogger/EncodingExtension/LoggingExtensionElement.cs" rel="nofollow noreferrer">element</a> and <a href="https://github.com/capslocky/WcfSoapLogger/blob/master/src/UsageExamples/ExampleBeta/Client/App.config" rel="nofollow noreferrer">config</a>.

I'm calling this web service within code and I would like to see the XML, but I can't find a property that exposes it.

How do I get the XML SOAP request of an WCF Web service request?

我正在代码中调用此web服务，我希望看到XML，但我找不到公开它的属性。
