Register Header in a SOAP service reference in C#

Question

I’d like some support. I’m in serious trouble with a client. I have a C# application that fetches data from a system and sends it to a SOAP service. It turns out that this SOAP service requires a header:

<soapenv:Header>
 <wsAutenticacao>
    <login>us1</login>
    <senha>b81476fc88f1a2a4</senha>
    <codigoEmpresa>1</codigoEmpresa>
 </wsAutenticacao>
</soapenv:Header>

When mapping through Visual Studio, I can’t find where to insert header data. The solution was not initiated by me and I need to continue in the same pattern.

Services are mapped in the app.config as Properties.Settings and not as Binding:

 <setting name="wsSGOSituacaoProjeto_SituacaoProjetoWSImplService"
                serializeAs="String">
   <value>http://ser:8080/erp/ws/situacaoProjeto</value>
 </setting>

The call in the reference contains nothing about the header:

public ProjetoWSImplService() {
            this.Url = global::Integracao.SGO.Properties.Settings.Default.Projeto_ProjetoWSImplService;
            if ((this.IsLocalFileSystemWebService(this.Url) == true)) {
                this.UseDefaultCredentials = true;
                this.useDefaultCredentialsSetExplicitly = false;
            }
            else {
                this.useDefaultCredentialsSetExplicitly = true;
            }
        }

        public new string Url {
            get {
                return base.Url;
            }
            set {
                if ((((this.IsLocalFileSystemWebService(base.Url) == true) 
                            && (this.useDefaultCredentialsSetExplicitly == false)) 
                            && (this.IsLocalFileSystemWebService(value) == false))) {
                    base.UseDefaultCredentials = false;
                }
                base.Url = value;
            }
        }

        public new bool UseDefaultCredentials {
            get {
                return base.UseDefaultCredentials;
            }
            set {
                base.UseDefaultCredentials = value;
                this.useDefaultCredentialsSetExplicitly = true;
            }
        }

        /// <remarks/>
        public event consultarProjetoCompletedEventHandler consultarProjetoCompleted;

        /// <remarks/>
        public event inserirCompletedEventHandler inserirCompleted;

        /// <remarks/>
        public event consultarCompletedEventHandler consultarCompleted;

        /// <remarks/>
        public event alterarCompletedEventHandler alterarCompleted;

The part of the code that is error due to missing header is as follows:

if (WebServiceSGO == null)
            {
                Iniciar("http://ser:8080/erp/ws/projeto?wsdl");
                //WebServiceSGO = new Integracao.SGO.wsSGOProjeto.ProjetoWSImplService();
            }
            WebClient client = new WebClient();
            var ret = WebServiceSGO.consultar(Param.Empresa, Param.EmpresaEspecificada, Param.UnidadeAdministrativa, Param.Datainicio, Param.DatainicioEspecificada, Param.Projeto, Param.AnoProjeto, Param.AnoProjetoEspecificado, Param.TipoProjeto, Param.Cliente, Param.ClienteEspecificado);
            return ToXML(ret);

Return: "Login Failure!"

You can set the header like this:

WebClient client = new WebClient();
client.Headers.Add("login", "us1");
client.Headers.Add("senha", "b81476fc88f1a2a4");
client.Headers.Add("codigoEmpresa", "1");
