I find this code and is resolve my problem.

http://arcware.net/setting-http-header-authorization-for-web-services/

protected override WebRequest GetWebRequest(Uri uri)
{
    // Assuming authValue is set from somewhere, such as the config file
    HttpWebRequest request = (HttpWebRequest)base.GetWebRequest(uri);
    request.Headers.Add("Authorization", string.Format("Basic {0}", authValue));
    return request;
}

Instead of modding the auto-generated code or wrapping every call in duplicate code  you can inject your custom HTTP headers by adding a custom message inspector  it s easier than it sounds   public class CustomMessageInspector   IClientMessageInspector       readonly string  authToken       public CustomMessageInspector string authToken                 authToken   authToken             public object BeforeSendRequest ref Message request  IClientChannel channel                var reqMsgProperty   new HttpRequestMessageProperty            reqMsgProperty Headers Add  Auth-Token    authToken           request Properties HttpRequestMessageProperty Name    reqMsgProperty          return null             public void AfterReceiveReply ref Message reply  object correlationState              public class CustomAuthenticationBehaviour   IEndpointBehavior       readonly string  authToken       public CustomAuthenticationBehaviour  string authToken                 authToken   authToken            public void Validate ServiceEndpoint endpoint               public void AddBindingParameters ServiceEndpoint endpoint  BindingParameterCollection bindingParameters               public void ApplyDispatchBehavior ServiceEndpoint endpoint  EndpointDispatcher endpointDispatcher               public void ApplyClientBehavior ServiceEndpoint endpoint  ClientRuntime clientRuntime                clientRuntime ClientMessageInspectors Add new CustomMessageInspector  authToken              And when instantiating your client class you can simply add it as a behavior   this Endpoint EndpointBehaviors Add new CustomAuthenticationBehaviour  Auth Token       This will make every outgoing service call to have your custom HTTP header

Here is what worked for me     protected override System Net WebRequest GetWebRequest Uri uri            HttpWebRequest request          request    HttpWebRequest base GetWebRequest uri           NetworkCredential networkCredentials           Credentials GetCredential uri   Basic            if  networkCredentials    null                        byte   credentialBuffer   new UTF8Encoding   GetBytes              networkCredentials UserName                     networkCredentials Password               request Headers  Authorization                  Basic     Convert ToBase64String credentialBuffer               request Headers  Cookie      BCSI-CS-2rtyueru7546356 1               request Headers  Cookie2       Version 1                     else                       throw new ApplicationException  No network credentials                      return request      Don t forget to set this property     service Credentials   new NetworkCredential  username    password        Cookie and Cookie2 are set in header because java service was not accepting the request and I was getting Unauthorized error

user334291 s answer was a life saver for me  Just want to add how you can add what the OP originally intended to do  what I ended up using    Overriding the GetWebRequest function on the generated webservice code   protected override System Net WebRequest GetWebRequest Uri uri        System Net WebRequest request   base GetWebRequest uri                 string auth    Basic     Convert ToBase64String System Text Encoding Default GetBytes this Credentials GetCredential uri   Basic   UserName         this Credentials GetCredential uri   Basic   Password        request Headers Add  Authorization   auth       return request      and setting the credentials before calling the webservice     client Credentials   new NetworkCredential user  password

It seems the original author has found their solution  but for anyone else who gets here looking to add actual custom headers  if you have access to mod the generated Protocol code you can override GetWebRequest   protected override System Net WebRequest GetWebRequest Uri uri      System Net WebRequest request   base GetWebRequest uri     request Headers Add  myheader    myheader value      return request      Make sure you remove the DebuggerStepThroughAttribute attribute if you want to step into it

If you want to send a custom HTTP Header  not a SOAP Header  then you need to use the HttpWebRequest class the code would look like   HttpWebRequest webRequest    HttpWebRequest WebRequest Create url   webRequest Headers Add  Authorization   token     You cannot add HTTP headers using the visual studio generated proxy  which can be a real pain

Are we talking WCF here  I had issues where the service calls were not adding the http authorization headers  wrapping any calls into this statement fixed my issue     using  OperationContextScope scope   new OperationContextScope RefundClient InnerChannel                   var httpRequestProperty   new HttpRequestMessageProperty                httpRequestProperty Headers System Net HttpRequestHeader Authorization     Basic                 Convert ToBase64String Encoding ASCII GetBytes RefundClient ClientCredentials UserName UserName                     RefundClient ClientCredentials UserName Password                OperationContext Current OutgoingMessageProperties HttpRequestMessageProperty Name    httpRequestProperty               PaymentResponse   RefundClient Payment PaymentRequest          This was running SOAP calls to IBM ESB via  NET with basic auth over http or https   I hope this helps someone out because I had massive issues finding a solution online
