Send mail with smtp SendAsync

Question

this is how when I need to send email gives me error. But the mistake that since gives me is this:

An asynchronous operation cannot be started at this tim

Answer 1

Change your method to:

public async Task SendEmail(string toEmailAddress, string emailSubject, string emailMessage)
{
var message = new MailMessage();
message.To.Add(toEmailAddress);

message.Subject = emailSubject;
message.Body = emailMessage;

using (var smtpClient = new SmtpClient())
{
    await smtpClient.SendMailAsync(message);
}
}

And call it like:

var task = SendEmail(toEmailAddress, emailSubject, emailMessage);
var result = task.WaitAndUnwrapException();
