Programação
#1

Pessoal, preciso consumir um webservice wsdl mas não sei como faço para carregar um método e passar os parametros dentro desse webservice para que ele me retorne o valor desejado.

Este é o webservice:

Criei a seguinte interface: 

public interface DLL {

        public String CalcularMediaParcial(String caminho,
                String GUID, int idEmpresa, int idGrupoEmpresa, int idUsuario, int idPeriodoLetivo,
                int idCurso, int idCiclo, int idSerie, int idFaseCalendario, int idProfessor, int idDisciplina,
                int idTurma);

        public void LiberarRecursos();
    }

Como faço para carregar webservice e chamar esse método CalcularMediaParcial?

Desde já agradeço.
