i am passing multiple addresses using following line of code.

Answer 1

I'm used "for" operator.

try
{
    string s = textBox2.Text;
    string[] f = s.Split(',');

    for (int i = 0; i < f.Length; i++)
    {
        MailMessage message = new MailMessage(); // Create instance of message
        message.To.Add(f[i]); // Add receiver
        message.From = new System.Net.Mail.MailAddress(c);// Set sender .In this case the same as the username
        message.Subject = label3.Text; // Set subject
        message.Body = richTextBox1.Text; // Set body of message
        client.Send(message); // Send the message
        message = null; // Clean up
    }

}

catch (Exception ex)
{

    MessageBox.Show(ex.Message);
}
