Я создал форму, которая позволяет клиенту загружать несколько (4) вложений.проблема в том, что когда форма отправляется на мою электронную почту, я получаю 4 вложения к почте, даже если клиент загрузил только 1 вложение.если он загрузил одно вложение, остальное я получу в виде «noname» файлов.как я могу это исправить?
это мой бэк-код (VB):
Imports System.Net.Mail
Partial Class SendAttachment
Inherits System.Web.UI.Page
Protected Sub DL1_SelectedIndexChanged(sender As Object, e As EventArgs)
If DropDownList1.SelectedItem.Text = "אחר" Then
q1.Visible = True
Else
q1.Visible= False
End If
If DropDownList1.SelectedItem.Text = "אחר" Then
q22.Visible = True
Else
q22.Visible= False
End If
End Sub
Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
'Make sure a file has been uploaded
If String.IsNullOrEmpty(AttachmentFile.FileName) OrElse AttachmentFile.PostedFile Is Nothing Then
Throw New ApplicationException("לא העלאת קבצים.")
End If
if AttachmentFile.PostedFile.ContentLength >600000 then
'display error file size should be less than 100kb
end if
'!!! UPDATE THIS VALUE TO YOUR EMAIL ADDRESS

'(1) Create the MailMessage instance
Dim mm As New MailMessage(UsersEmail.Text, ToAddress)
'(2) Assign the MailMessage's properties
mm.Subject = Subject.text & "-" & pi1.text
mm.Body = textMsg
mm.IsBodyHtml = false
'Attach the file
AttachmentFile.PostedFile.InputStream.Position = 0
mm.Attachments.Add(New Attachment(AttachmentFile.PostedFile.InputStream, AttachmentFile.FileName))
mm.Attachments.Add(New Attachment(AttachmentFile2.PostedFile.InputStream, AttachmentFile2.FileName))
'(3) Create the SmtpClient object
Dim smtp As New SmtpClient
'(4) Send the MailMessage (will use the Web.config settings)
smtp.Send(mm)
'Show the EmailSentForm Panel and hide the EmailForm Panel
EmailSentForm.Visible = True
EmailForm.Visible = False
End Sub
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
'On the first page load, hide the EmailSentForm Panel
EmailSentForm.Visible = False
End If
End Sub
End Class
