Sending Mail via SMTP in C# using BCC without TO

Question

I am trying to use the System.Net.Mail.MailMessage class in C# to create an email that is sent to a list of email addresses all via BCC. I do not want to include a TO address, but it seems that I must because I get an exception if I use an empty string for the TO address in the MailMessage constructor. The error states:

ArgumentException
The parameter 'addresses' cannot be an empty string.
Parameter name: addresses

Surely it is possible to send an email using only BCC as this is not a limitation of SMTP.

Is there a way around this?

Answer 1

It doesn't even need to be a real e-mail address, I typically use [e-mail] for TO, and NoReply@CompanyName for FROM.

Answer 2

Just don't call the Add-method on the To-property.
