Need help with manipulating SOAP header in my WCF client before sending request?

Check out the following article which shows you an example of how to implement an IClientMessageInspector which alters the message and injects a custom header Handling custom SOAP headers via WCF Behaviors First you need to define a custom header to represent the contents of a SOAP header. To do so create your own descendant of the MessageHeader class public class MyHeader : MessageHeader { //... } Create an IClientMessageInspector implementation that injects your custom header just before sending the request (BeforeSendRequest) public class CustomMessageInspector : IClientMessageInspector { public object BeforeSendRequest(ref Message request, IClientChannel channel) { MessageBuffer buffer = request. CreateBufferedCopy(Int32. MaxValue); request = buffer.CreateMessage(); request.Headers.

Add(new MyHeader()); return null; } //... } Now you need to add your custom message inspector to the WCF pipeline, but you already got this part covered The Message parameter of the BeforeSendRequest(ref Message request, IClientChannel channel) can be used to read the SOAP message using one of the methods of the Message type (ToString(), GetBody() GetReaderAtBodyContents() etc. ) To get the body of the message use the GetReaderAtBodyContents() method which returns an XmlDictionaryReader object. Use this XML reader to retrieve the body as a string For example: using (XmlDictionaryReader reader = message. GetReaderAtBodyContents()) { string content = reader.ReadOuterXml(); //... }.

I am using the BeforeSendRequest method, what I need help with his>>>>>>> 1. How do I extract the body of the SOAP request and convert that to string and pass it as an input to my "CreateX509SoapEnvelope" method? 2.

After the header is stitched together in the method, the output of the "CreateX509SoapEnvelope" is a string as well. Now I need to take the string and convert that so that I can use the request.WriteHeader() method. PLEASE CHECK mY CODE ABOVE – wcfvemi Aug 20 at 14:11 Updated my answer.

Please check the part I added about the GetReaderAtBodyContents() method. – Christophe Geers Aug 20 at 16:05.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
