我想調(diào)用一個 Web 服務(wù)，我想獲取請求和響應(yīng)對象作為肥皂消息。var response = client.invoke(parameter);我想以某種方式發(fā)送消息并接收消息。

基于來自 Carlos Figueira 的 MSDN 文章WCF Extensibility – Message Inspectors，一種選擇是使用 MessageInspector。
創(chuàng)建一個實現(xiàn)EndBehavior和ClientMessageInspector的類。緩沖請求和回復(fù)消息，以便稍后使用它們。在這個例子中，我在控制臺中打印它們。
這是組合的實現(xiàn)：
// using System.ServiceModel.Description;
// using System.ServiceModel.Dispatcher;
// using System.ServiceModel.Channels;
// using System.ServiceModel
public class InspectBehaviorAndnspector : IEndpointBehavior, IClientMessageInspector
{
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
clientRuntime.MessageInspectors.Add(this);
}
public MessageBuffer RequestBuffer;
public MessageBuffer ReplyBuffer;
public void AfterReceiveReply(ref Message reply, object correlationState){
// messages are read only
ReplyBuffer = reply.CreateBufferedCopy(2048);
// so recreate the message after it was buffered
reply = ReplyBuffer.CreateMessage();
}
public object BeforeSendRequest(ref Message request, IClientChannel channel){
// messages are read only
RequestBuffer = request.CreateBufferedCopy(2048);
// so recreate the message after it was buffered
request = RequestBuffer.CreateMessage();
return "42";
}
// not needed for client
public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
{
}
public void Validate(ServiceEndpoint sep)
{
}
public void AddBindingParameters(ServiceEndpoint sep, BindingParameterCollection bpc)
{
}
}
現(xiàn)在在您的client實例上，假設(shè)它源自ClientBase，您可以執(zhí)行以下操作：
var inspector = new InspectBehaviorAndnspector();
client.Endpoint.Behaviors.Add(inspector);
// this is your call
var response = client.invoke(parameter);
// either do a ToString
Console.WriteLine(inspector.RequestBuffer.CreateMessage().ToString());
// or Write it with XmlWriter
var sb = new StringBuilder();
using(var xw = XmlWriter.Create(sb, new XmlWriterSettings {Indent =true})) {
inspector.ReplyBuffer.CreateMessage().WriteMessage(xw);
}
Console.WriteLine(sb.ToString());
我在一個帶有添加服務(wù)的例子中運行了這個，這是我的結(jié)果：
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">

<Action s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">http://tempuri.org/ISelfHostTest/Add</Action>
