How to create SOAP request header with Security.

[bhu]

I have a simple helloworld web service ,
when i call this service from the client this is the message sent.
-----SoapRequest at 6/7/2006 10:18:11 PM
<?xml version="1.0" encoding="utf-8"?><soap:Envel ope
xmlns:soap="htt p://schemas.xmlsoap .org/soap/envelope/"
xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http ://www.w3.org/2001/XMLSchema"><soa p:Body><HelloWo rld
xmlns="http://tempuri.org/" /></soap:Body></soap:Envelope>

i got this by creating the soaplogger class
but i want to create a soap message like this.
<soapenv:Header >
<wsse:Securit y xmlns:wsse:=htt p://schemas.xmlsoap .org/ws/2003/06/secext
soapenv:mustUnd erstand="1">
<wsse:UsernameT oken>
<wsse:Usernam e>----Username here---</wsse:Username>
<wsse:Passwor d>---PW here ------</wsse:Password>
</wsse:UsernameTo ken>
</wsse:Security>
</soapenv:Header>

The C# client code is this.
ClientApp.TESTS ERVER.Service1W se proxy = new
ClientApp.TESTS ERVER.Service1W se();
UsernameToken tok = new
UsernameToken(" kkkkk","bhu***" ,PasswordOption .SendPlainText) ;
proxy.RequestSo apContext.Secur ity.Tokens.Add( tok);
textBox1.Text = proxy.HelloWorl d();

Can any one please let me know, how to resolve this issue.

thank you
