如何确定SoapMessage位置，服务器或客户端。

如何确定是否在客户端或服务器端调用传递给 SoapExtenion 的 ProcessMessage 方法的消息？

我看到有 SoapServerMessage 和 SoapClientMessage 类型。查看我的 ProcessMessage 方法：

How do you determine if the message passed to the ProcessMessage method of a SoapExtenion is being called on the client side or server side?

I see that there are SoapServerMessage and SoapClientMessage types. Look at my ProcessMessage method:

        public override void ProcessMessage(SoapMessage message)
        {
            WriteMessageType(message);
            switch (message.Stage)
            {
                 // cases left out intentionally for brevity
            }
        }

如果我输出传递给上述方法的 SoapMessage 的类型，这是我得到的：

If I output the type of SoapMessage being passed to the above method, here is what I get:

System.Web.Services.Protocols.SoapServerMessage
System.Web.Services.Protocols.SoapServerMessage
System.Web.Services.Protocols.SoapServerMessage
System.Web.Services.Protocols.SoapServerMessage

每次为 SoapMessageState 调用 ProcessMessage 方法时，有四行不同的行。所以，我问，如果消息类型始终是 SoapServerMessage ，如何在每个 SoapMessageStage 中分辨代码运行的位置？

Four different lines for each time the ProcessMessage method is called for each SoapMessageState. So, I ask, how can I tell where the code is running during each SoapMessageStage if the message type is always a SoapServerMessage?

Thanks.
