The parameter 'addresses' cannot be an empty string

Question

I am trying to send an email asp.net, using the System.Net.Mail.SmtpClient class.

However I am getting the following exception message:

The parameter         


        

Answer 1

This exception is being thrown by the MailAddress constructor. It means you are trying to add an empty string as an email address, which is not valid.

In this case it means toEmailAddress is an empty string.

Answer 2

try

message.To.Add(New MailAddress(toEmailAddress));

and verify the content of the variable "toEmailAddress".
