I have been struggling for two days to generate a simple HTML email with a .NET application. There are several answered questions on this topic already, and in each case the syntax is relatively simple. It still took me over a day to get it to work. However, the solution raises more questions. I have looked to the Microsoft documentation and found nothing there.
This syntax works and will generate an HTML email:
MailMessage message = new MailMessage(); message.Subject = "Test"; message.From = new MailAddress("[email protected]"); message.To.Add("[email protected]"); message.Body = "<strong>This is a test</strong>"; message.IsBodyHtml = true; smtpClient.Send(message);
However, if I use the Send method of the SmtpClient object that has a signature with four parameters, it will NOT generate an HTML email:
smtpClient.Send("[email protected]", "[email protected]", message.Subject, message.Body);
Can anyone explain why this is happening. Is it documented, or is it a known "issue"? IsBodyHtml was set to true in both cases.
