SoapException - Missing Header Information

Question

I am trying to get some data from a web service, using a simple console application, however I am getting this error:

SoapException was unhandled
Error - Missing Header Information.

I have already tried the below articles:

• http://www.codeproject.com/Questions/709641/ERROR-SOAP-Header-Missing
• http://msdn.microsoft.com/en-us/library/y4t36w86(v=vs.80).aspx

But I am not allowed to work on the WebServer side, so there is not much I can do.

Code:

namespace ConsoleApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            myWS.WServer WebService = new myWS.WServer();
            string[] myMethods = WebService.GetMethods();
        }
    }
}

Follows the full error message:

System.Web.Services.Protocols.SoapException was unhandled

Despite the problem above, using SoapUI and XML, it does works well.

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ver="http://www.multispeak.org/Version_3.0">
   <soapenv:Header>
      <ver:MultiSpeakMsgHeader Version="3.0" UserID="myId" Pwd="myPwd" AppName="?" AppVersion="?" Company="?" CSUnits="feet" CoordinateSystem="?" Datum="?" SessionID="?" PreviousSessionID="?" ObjectsRemaining="?" LastSent="?" RegistrationID="?"/>
   </soapenv:Header>
   <soapenv:Body>
      <ver:GetMethods/>
   </soapenv:Body>

I am thinking that the problem is related to authentication, since I do not set any credentials in the console applications.

Answer 1

I figured out how to solve it.
It was related to the authentication, as the example below:

WebService .MultiSpeakMsgHeaderValue = new MultiSpeakMsgHeader {
    Pwd = "***",
    UserID = "***"
};

Before call the methods.
