发送带有C＃和XAML附件的电子邮件

Question

I am building a windows 8 desktop app. I have an email form with a textbox and a button. XAML below.

<TextBox x:Name="email_txt"></TextBox>
<Button x:Name="email_btn" Content="Emial Me"  Click="email_btn_Click"/>

How do I send a an email with an attachment to the email address entered in email_txt when email_btn is clicked.

I used the following in the c# code behind the XAML page

 private async void email_btn_Click(Object sender, RoutedEventArgs e)
        {
            var mailto = new Uri("mailto:?to=tr@gmail.com&subject=Hello&body=Test Tocuh Email");
            await Windows.System.Launcher.LaunchUriAsync(mailto);*/

        }

This code just opens MS Outlook with the message type.

How do I send an email with an attachment when the button is clicked?

Answer 1

Consider using SmtpClient class. Note that this class by default will take smtp configurations from you application config file.

        var mailMessage = new MailMessage("test@example.com", email_txt.Text, "Hello", "Test");
        mailMessage.IsBodyHtml = true;
        byte[] attachmentData; //get attachment data as byte array.
        var attachmentStream = new MemoryStream(attachmentData);
        var attachment = new Attachment(attachmentStream, "Test");

        mailMessage.Attachments.Add(attachment);

        var smtpClient = new SmtpClient(smtpServer);
        smtpClient.Send(mailMessage);

The WinRT (Win App) platform doesn't have any built-in SMTP client. Instead you can use the share charm in order to send emails.

See Sharing content source app sample .

I would include some code, but I'm not on my Windows 8 machine.
