Estou tendo este problema na segunda vez que chamo o webservice.
Sempre na primeira vez funciona, porém na segunda não...
Alguem poderia me ajudar?
o erro ocorre nessa linha:
var teste = tipoInstance.GetMethod(methodName).Invoke(wsvcClass, args);
Segue o codigo:
ConnectionLib.WsProxy opa = new ConnectionLib.WsProxy();
opa.CallWebService("https://urldoservico"
, "NfseServicesService" //nome do servico
, "EnviarLoteRpsSincrono" //nome do metodo
, new object[]{ File.ReadAllText(@"arquivo.xml") }
, new X509Certificate2(@"C:\Projetos\Branch\Framework\NFE\Certificado\certificado.pfx", "senhadocertificado"));
