Rewrite SOAP request message before sending

For debugging purposes, I needed to alter the xml SOAP request completely before sending the request.

In this post, I showed how to log all outgoing SOAP request by using IClientMessageInspector. I’d use the same method to alter the request before sending.

public object BeforeSendRequest(ref Message request, IClientChannel channel)
{
    var message = "new xml goes here";
            
    var bytes = Encoding.UTF8.GetBytes(message);
    var reader = XmlDictionaryReader.CreateTextReader(bytes, XmlDictionaryReaderQuotas.Max);

    request = Message.CreateMessage(request.Version, request.Headers.Action, reader);

    return null;
}
