Hello sirs,

System.Net.WebException:"The request was aborted: Could not create SSL/TLS secure channel" em System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request) em System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request) em System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) em NfseWSService.ConsultarSituacaoLoteRps(String nfseCabecMsg, String nfseDadosMsg)

Source code:

public string InvokeStr(object Instance, string methodName, object[] parameters)
{
//Relacionar o certificado digital que será utilizado no serviço que será consumido do webservice
Type tipoInstance = Instance.GetType();
object oClientCertificates = tipoInstance.InvokeMember("ClientCertificates", System.Reflection.BindingFlags.GetProperty, null, Instance, new Object[] { });
Type tipoClientCertificates = oClientCertificates.GetType();
tipoClientCertificates.InvokeMember("Add", System.Reflection.BindingFlags.InvokeMethod, null, oClientCertificates, new Object[] { this.oCertificado });
//Invocar método do serviço

return (string)tipoInstance.GetMethod(methodName).Invoke(Instance, parameters);
