我们在公司内部网上有一个用户输入数据的表单，然后他们点击提交数据，这些数据被编译成电子邮件并发送到特定的用户列表。我们有site.aspx.cs，我指定通过电子邮件发送的数据。
我们正在添加一个字段，用户可以在执行表单时上传文件，但是我在将此文件添加到.cs文件时遇到问题，以便它可以通过电子邮件发送数据。
这是我创建字段的HTML和上传按钮

以下是.cs我目前已经说过，电子邮件将在正文中发送这些当前字段。我需要知道如何将HTML发送的文件作为附件发送到此电子邮件中。有什么想法吗？
protected void Button1_Click(object sender, EventArgs e)
{
String toAddress = ""; String fromAddress = "doNotReply@companyemail.com";
SmtpClient smtpClient = new SmtpClient("mail.companyemail.com");
smtpClient.Port = 25;
MailMessage message = new MailMessage();
message.IsBodyHtml = false;
message.Priority = MailPriority.High;
message.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
try
{
message.Subject = "Program Change";
message.Body = "Part Number: " + txtPartNumber.Text.Trim() + "\n";
message.Body += "Employee ID: " + txtEmployeeID.Text.Trim() + "\n";
message.Body += "Current Job Number: " + txtCurrentJobNumber.Text.Trim() + "\n" + "\n";
message.Body += "Revision Level: " + txtRevisionLevel.Text.Trim() + "\n";
message.Body += "Operation Number: " + txtOperationNumber.Text.Trim() + "\n";
message.Body += "Proposed Changes: " + txtProposedChange.Text.Trim() + "\n";
message.Body += "Reason for Proposed Change: " + txtChangeReason.Text.Trim() + "\n";
HttpPostedFile file = Request.Files["file"];
Attachment attachment = new Attachment(file.InputStream, file.FileName);
message.Attachments.Add(attachment);
toAddress += "user@companyemail.com";
smtpClient.Send(fromAddress, toAddress, message.Subject, message.Body);
}
catch (Exception ex)
{
formPanel.Visible = false;
errorPanel.Visible = true;
}
formPanel.Visible = false;
errorPanel.Visible = false;
successPanel.Visible = true;
}
答案 0 :(得分：0)
从发布的表单中抓取文件。
HttpPostedFile file = Request.Files["file"];
然后，将其添加为附件。
Attachment attachment = new Attachment(file.InputStream, file.FileName);
message.Attachments.Add(attachment);
注意，我还没有测试过这段代码。
