the Parameter 'address' cannot be an empty string

Question

try

{

MailMessage message = new MailMessage();

message.To.Add("[e-mail]");

message.From = new MailAddress(textBox1.Text);

message.Subject = "BUG REPORT";

if (radioButton1.Checked == true)

{

message.Body = textBox2.Text;

}

if (statusf == "nono")

{

message.Body = statusf + "\n\n\n" + textBox3.Text;

}

if (statusf == "noyes")

{

message.Body = statusf + "\n\n\n" + textBox3.Text;

}

SmtpClient client = new SmtpClient("smtp-server.neo.rr.com");

client.Send(message);

}

catch (Exception ex)

{

MessageBox.Show(ex.Message.ToString());

}

 

 

i cant figure out what that error message means? its saying the address cannot be an empty string? any help would be appreciated

Answer 1

message.From = new MailAddress(textBox1.Text);

 

The "From" is not a new MailAddress

 

It's looking for the from address for the existing mailmessage not a new one.

 

so:

 

message.From = textBox1.Text;

mailMessage.From = email.Text;

throws error:

Cannot implicitly convert type 'string' to 'System.Net.Mail.MailAddress'    C:\Prace\webroot\BioNea\BioNea\Controls\ContactForm.ascx.cs

Where is the message.To address? Coult it be the problem? It is an empty string in your setup.

This is how the mailAddress is formed:

MailAddress from = new MailAddress("[e-mail]", "Ben Miller");
MailAddress to = new MailAddress("[e-mail]", "Jane Clayton");

Answer 5

message.From = new MailAddress(textBox1.Text);

you will get this exception if textBox1.Text is String.Empty

Answer 6

Hello,

I have a similar problem when I had the "To" to a specific address when I do it again, it sends me the email to the new address and to the first one. Is there a way to reset or empty the "To" so this stops happening?

Thanks
