Question

I am sure this is an easy question however I am not finding the solution. I want to save the XML files posted to my .NET Web Service. I am sure it is just a simple method call when the service is invoked but I am not finding it. I would like to save the full XML posted to the service

Any help would be greatly appreciated. Thank you in advance.

Thank you for your help however I found what I was looking for at http://msdn.microsoft.com/en-us/library/system.web.services.protocols.soapextension.aspx

To help anyone else that is new to tring to implement this via WebService’s I included the steps that I performed to implement it and modifications so I could save it to the db as well as the file system I performed the following steps. If you have any questions please feel free to aks and I will be happy to answer.

1. Created a code file in my web service project with the code listed in the in the article

2. Created a few properties to store values to save to the db

   private string _requestXml;
   private DateTime _start;
   

3. Then I modified the WriteInput method to save values to those variables.

   public void WriteInput(SoapMessage message)
   {
       //Begin Edit
       oldStream.Position = 0;
       _requestXml = new StreamReader(_oldStream).ReadToEnd();
       _start = DateTime.UtcNow;
       //End Edit
       //Begin Original Code
       oldStream.Position = 0;
       Copy(oldStream, newStream);
       var fs = new FileStream(filename, FileMode.Append, FileAccess.Write);
       var w = new StreamWriter(fs);
       var soapString = (message is SoapServerMessage) ? "SoapRequest" : "SoapResponse";
       w.WriteLine("-----" + soapString + " at " + DateTime.Now);
       w.Flush();
       newStream.Position = 0;
       Copy(newStream, fs);
       w.Close();
       newStream.Position = 0;
   }
   

4. Then I modified the WriteOutput to

   public void WriteOutput(SoapMessage message)
   {
       //Begin Edit
       var responseXml = new StreamReader(newStream).ReadToEnd();
       newStream.Position = 0;
       //Start process for saving to DB 
       //"_requestXml" = Original Request Soap Message
       //"responseXml" = Service Returned Response
       //"_start" = Request Start Time
       //message.MethodInfo.Name = I save this so I know what method from     
       //message.Url = I save this so I know the original ASMX that was hit
       //End Edit
       //Begin Original Code
       newStream.Position = 0;
       var fs = new FileStream(filename, FileMode.Append, FileAccess.Write);
       var w = new StreamWriter(fs);
       var soapString = (message is SoapServerMessage) ? "SoapResponse" : "SoapRequest";
       w.WriteLine("-----" + soapString + " at " + DateTime.Now);
       w.Flush();
       Copy(newStream, fs);
       w.Close();
       newStream.Position = 0;
       Copy(newStream, oldStream);
   }
   

5. Now all that’s left is to add the following to your service call and you should be good to go

   [WebMethod, NameSpace.OfyourTraceExtesionClass.TraceExtension]
   public void WebMethod1()
   {
       //DoSomeStuff
   }
