記錄兩個webservice請求，在SoapExtension中的響應

Question

我正在使用SoapExtension來記錄web服務請求，在web服務中發生錯誤時的響應。請求和響應XMLDocument的數據都不正確。有人可以查看代碼，看看我可能做錯了什麼嗎？如果我無法集中SoapExtension中的更改，那麼我將圍繞每個Web服務端點添加日誌記錄代碼。

通過刪除XMLRequest，XMLResponse屬性的「Static」屬性來解決此問題。此外，我將在「SoapMessageStage.AfterSerialize」過程中獲取「XMLResponse」，在「SoapMessageStage.BeforeSerialize」過程中獲取「XMLRequest」。我以前已經切換了。

using System.Xml; 

using Elmah; 

public class ElmahSoapExtensionV2 : SoapExtension 
{ 
    private Stream oldStream; 
    private Stream newStream; 

    public XmlDocument XmlRequest { get; private set; } 
    public XmlDocument XmlResponse { get; private set; } 

    public override Stream ChainStream(Stream stream) 
    { 
     oldStream = stream; 
     newStream = new MemoryStream(); 
     return newStream; 
    } 

    public override void ProcessMessage(SoapMessage soapMessage) 
    { 
     switch (soapMessage.Stage) 
     { 
      case SoapMessageStage.BeforeSerialize: 
       break; 
      case SoapMessageStage.AfterSerialize: 
       XmlResponse = GetSoapEnvelope(newStream); 
       if (soapMessage.Exception != null) 
       { 
        var exception = soapMessage.Exception.GetBaseException(); 
        exception.Data.Add("SoapRequest", XmlRequest.OuterXml); 
        exception.Data.Add("SoapResponse", XmlResponse.OuterXml); 
        ErrorSignal.FromCurrentContext().Raise(exception); 
       } 
       CopyStream(newStream, oldStream); 
       break; 
      case SoapMessageStage.BeforeDeserialize: 
       CopyStream(oldStream, newStream); 
       XmlRequest = GetSoapEnvelope(newStream); 
       break; 
      case SoapMessageStage.AfterDeserialize: 
       break; 
     } 
    } 

    private static XmlDocument GetSoapEnvelope(Stream stream) 
    { 
     var xmlDocument = new XmlDocument(); 
     stream.Position = 0; 
     var streamReader = new StreamReader(stream); 
     xmlDocument.LoadXml(streamReader.ReadToEnd()); 
     stream.Position = 0; 
     return xmlDocument; 
    } 

    private static void CopyStream(Stream streamFrom, Stream streamTo) 
    { 
     var textReader = new StreamReader(streamFrom); 
     var textWriter = new StreamWriter(streamTo); 
     textWriter.WriteLine(textReader.ReadToEnd()); 
     textWriter.Flush(); 
    } 

    #region MyRegion 
    public override object GetInitializer(LogicalMethodInfo methodInfo, SoapExtensionAttribute attribute) 
    { 
     return null; 
    } 
    public override object GetInitializer(Type WebServiceType) 
    { 
     return null; 
    }
