var task = Task.Run(async () => await SendEmail(solicitud, tipoDeLaSolicitud));
I want to send an email in the background so that the user doesn't need to wait for the email to be sent.
In order to achieve this I have run a Task.Run() for the process runs in the background and not in the same thread. When SendEmailSolicitanteAsync calls GetUserDomainByUserName and finishes is jumping to MultiDbContextConnectionStringResolver.GetNameOrConnectionString method causing an object null reference exception and crashing the program. I don't understand why is jumping to that context because I'm not doing interacting with the database.
Please help and thank you before hand.
private async Task SendEmail(Solicitud solicitud, TipoSolicitud tipoDeLaSolicitud)
{
Logger.Info("Evento crear una solicitud fue ejecutado.");
await _solicitudEmailer.SendEmailSolicitanteAsync(solicitud.EmailSolicitante,
tipoDeLaSolicitud.Nombre,
solicitud.CodigoSolicitud,
solicitud.Aprobadores.Split(","), true);
}
public async Task SendEmailSolicitanteAsync(string to, string tipoSolicitud, string codigoSolicitud, string[] aprobadores, bool appendLinkUrl)
{
var tasks = aprobadores.Select(aprobador => _userDomainAppService.GetUserDomainByUserName(aprobador));
var listAprobadores = await Task.WhenAll(tasks);
// more code but it is not necessary for me to put it
}
public async Task<UsersDomain> GetUserDomainByUserName(string userName)
{
UsersDomain userDomain = null;
var response = await _clientHttp.GetAsync(_urlGetUser + userName);
if (response.IsSuccessStatusCode)
{
userDomain = await response.Content.ReadAsAsync<UsersDomain>();
}
return userDomain;
}
public class MultiDbContextConnectionStringResolver : DefaultConnectionStringResolver
{
private readonly IAbpStartupConfiguration _configuration;
public MultiDbContextConnectionStringResolver(IAbpStartupConfiguration configuration)
: base(configuration)
{
_configuration = configuration;
}
public override string GetNameOrConnectionString(ConnectionStringResolveArgs args)
{
if (args["DbContextConcreteType"] as Type == typeof(SICIDbContext))
{
// var configuration = AppConfigurations.Get(WebContentDirectoryFinder.CalculateContentRootFolder());
return (string)_configuration.Get(TestConsts.ConnextionStringNameSici);
