C#

Hi all

I have been searching and have found very little on this subject.

I am trying to connect simply to a webservice, call a  method and get a response.

The service requires a nonce for authentication, but i can not ofr the life of me figure out how to generate one and pass it correctly.

I am call the webservice from a c# script using webClient.
I can add basic network credentials, of username and password.

But how do i add the full header correctly with a generated nonce.

The authentication part of the header looks like this.
<pre lang="xml">    <SOAP-ENV:Header>
       <wsse:Security mustUnderstand="true">
          <wsse:UsernameToken>
             <wsse:Username>admin</wsse:Username>
             <wsse:Password
Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">bG4Gz8elJibVIABSaX5nB7uTSBM=</wsse:Password>
             <wsse:Nonce
EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">+MnwDfmScWNR2j5MBV+Ikg==</wsse:Nonce>
<wsu:Created>2014-03-06T12:37:36.174525Z</wsu:Created>
          </wsse:UsernameToken>
       </wsse:Security>
    </SOAP-ENV:Header>
</pre>

I am new to using webservices so for give my ignorance.
