Consuming web service with c# and basic authentication [duplicate]

Answer 1

For you to be able to call the web-service you will need to add security information to the SOAP header.

Click here to read an MSDN article that explains the basic principle.

Take a look at the code sample below and see if it solves your problem:

 var client = new WCClient();  
 using (OperationContextScope scope = new OperationContextScope(client.InnerChannel))
 {
     var httpRequestProperty = new HttpRequestMessageProperty();
     httpRequestProperty.Headers[System.Net.HttpRequestHeader.Authorization] = "Basic " +
                  Convert.ToBase64String(Encoding.ASCII.GetBytes(client.ClientCredentials.UserName.UserName + ":" +
                  client.ClientCredentials.UserName.Password));
     OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = httpRequestProperty;

     client.DoSomething();
 }
