该怎么做?这是我目前的代码,这是一个Windows窗体:
mail.From = New MailAddress(TextBox2.Text) mail.To.Add(New MailAddress(TextBox1.Text)) mail.Subject = TextBox3.Text mail.Body = TextBox4.Text mail.IsBodyHtml = True Dim client As SmtpClient = New SmtpClient("smtp.gmail.com") client.EnableSsl = True client.Credentials = New System.Net.NetworkCredential(TextBox2.Text,TextBox5.Text) Try client.Send(mail) Catch ex As Exception MessageBox.Show("Sending email Failed. Please Try again") End Try
Here就是一个很好的例子
