Question

我有以下代码，但它不起作用 - 使用message.To时出现错误，然后我将其更改为message.To.Add但没有任何成功。

我不知道ASP.net，我只想让这个东西工作。任何帮助表示赞赏。

using System.Net.Mail;


protected void btnsubmit_Click(object sender, EventArgs e)
{
    string body = "";
    string fileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
    body = "<table border='0' align='center' cellpadding='2' style='border-collapse: collapse' bordercolor=''#111111' width='100%' id='AutoNumber1'>";
    body = body + "<tr><td width='100%' align='center' colspan='6'><b>Photo Submission Form</b></td></tr>";
    body = body + "<tr><td width='100%' colspan='6'>&nbsp;</td></tr>";
    body = body + "<tr><td width='50%' colspan='2'>Name</td><td width='50%' colspan='4'><b>" + name.Text + "</b></td></tr>";
    body = body + "<tr><td width='50%' colspan='2'>E-Mail</td><td width='50%' colspan='4'><b>" + email.Text + "</b></td></tr>";
    body = body + "<tr><td width='50%' colspan='2'>Caption</td><td width='50%' colspan='4'><b>" + caption.Text + "</b></td></tr>";
    body = body + "<tr><td width='50%' colspan='2'>Phone</td><td width='50%' colspan='4'><b>" + phone.Text + "</b></td></tr>";
    MailMessage message = new MailMessage();
    Attachment myAttachment = new Attachment(FileUpload1.FileContent, fileName);
    message.To.Add(new MailAddress("contact@xxxx.com"));
    message.From = New MailAddress(email.Text);
    message.Subject = "Photo Submission Form";
    message.BodyFormat = MailFormat.Html;
    message.Body = body;
    message.Attachments.Add(myAttachment);
    SmtpMail.SmtpServer.Insert(0, "");
    SmtpMail.Send(message);
    RegisterStartupScript("startupScript", "<script language=JavaScript>alert('Message sent successfully.');</script>");

The Attachment class is used with the MailMessage class. All messages
包含一个Body，其中包含消息的内容。此外身体，你可能想发送其他文件。这些是作为发送附件和表示为附件实例。添加一个附加到邮件消息，添加它到MailMessage.Attachments 集合。
Attachment content can be a String, Stream, or file name. You can
指定附件中的内容通过使用任何附件构造
The MIME Content-Type header information for the attachment is
由ContentType表示的
属性。 Content-Type标头指定媒体类型和子类型以及任何相关参数。使用 ContentType来获取实例与附件相关联。
The MIME Content-Disposition header is represented by the
ContentDisposition属性。该 Content-Disposition标头指定演示文稿和文件时间戳为了附件。一个 Content-Disposition标头已发送仅当附件是文件时。使用获取的ContentDisposition属性与...相关联的实例附件。
The MIME Content-Transfer-Encoding header is represented by the
TransferEncoding属性。

        public static void CreateMessageWithAttachment(string server)
        {
            // Specify the file to be attached and sent.
            // This example assumes that a file named Data.xls exists in the
            // current working directory.
            string file = "data.xls";
            // Create a message and set up the recipients.
            MailMessage message = new MailMessage(
               "jane@contoso.com",
               "ben@contoso.com",
               "Quarterly data report.",
               "See the attached spreadsheet.");

            // Create  the file attachment for this e-mail message.
            Attachment data = new Attachment(file, MediaTypeNames.Application.Octet);
            // Add time stamp information for the file.
            ContentDisposition disposition = data.ContentDisposition;
            disposition.CreationDate = System.IO.File.GetCreationTime(file);
            disposition.ModificationDate = System.IO.File.GetLastWriteTime(file);
            disposition.ReadDate = System.IO.File.GetLastAccessTime(file);
            // Add the file attachment to this e-mail message.
            message.Attachments.Add(data);

            //Send the message.
            SmtpClient client = new SmtpClient(server);
            // Add credentials if the SMTP server requires them.
            client.Credentials = CredentialCache.DefaultNetworkCredentials;

  try {
              client.Send(message);
            }
            catch (Exception ex) {
                       //Handle...

            }

            data.Dispose();
        }
