Question

程序使用G-mail帐户从您的计算机发送短信。此代码工作正常，但需要一些总时间，并且它当前正在向4个不同的电子邮件地址发送文本，只有一个正常工作。所以，想法或帮助会很棒。

帮助编写一个循环或类似的东西来简化我的代码？

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Try

        Dim Smtp_Server As New SmtpClient
        Dim e_mail As New MailMessage()
        Dim self As New MailAddress("blank@gmail.com")
        Dim Sprint As String
        Dim Verizon As String
        Dim TMobile As String
        Dim ATT As String

        Smtp_Server.UseDefaultCredentials = False
        Smtp_Server.Credentials = New Net.NetworkCredential("blank@gmail.com", "password")
        Smtp_Server.Port = 587
        Smtp_Server.EnableSsl = True
        Smtp_Server.Host = "smtp.gmail.com"

        Sprint = "@pm.sprint.com"
        Verizon = "@vtext.com"
        TMobile = "@tmomail.net"
        ATT = "@txt.att.net"


        If txtTo.Text.Length > 1 Then
            e_mail = New MailMessage()
            e_mail.From = self
            e_mail.To.Add(txtTo.Text + Sprint) 'Spint
            e_mail.Subject = txtSubject.Text
            e_mail.IsBodyHtml = False
            e_mail.Body = txtMessage.Text
            Smtp_Server.Send(e_mail)

            e_mail = New MailMessage()
            e_mail.From = self
            e_mail.To.Add(txtTo.Text + ATT) ' AT&T

            Smtp_Server.Send(e_mail)

            e_mail = New MailMessage()

            e_mail.To.Add(txtTo.Text + Verizon) ' Verizon
            e_mail.Subject = txtSubject.Text
            e_mail.IsBodyHtml = False
            e_mail.Body = txtMessage.Text
            Smtp_Server.Send(e_mail)

            e_mail = New MailMessage()
            e_mail.From = self
            e_mail.To.Add(txtTo.Text + TMobile) ' T-mobial
            e_mail.Subject = txtSubject.Text

这无助于加快您的发送速度...但它会使用您请求的循环减少您的代码行...

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Try

        Dim Smtp_Server As New SmtpClient
        Dim e_mail As New MailMessage()
        Dim self As New MailAddress("blank@gmail.com")
        Dim strCarriers as New List(of String)

        Smtp_Server.UseDefaultCredentials = False
        Smtp_Server.Credentials = New Net.NetworkCredential("blank@gmail.com", "password")
        Smtp_Server.Port = 587
        Smtp_Server.EnableSsl = True
        Smtp_Server.Host = "smtp.gmail.com"

        strCarriers.Add("@pm.sprint.com")
        strCarriers.Add("@vtext.com")
        strCarriers.Add("@tmomail.net")
        strCarriers.Add("@txt.att.net")

        If txtTo.Text.Length > 1 Then

            For Each Carrier As String In strCarriers

                e_mail = New MailMessage()
                e_mail.From = self
                e_mail.To.Add(txtTo.Text + Carrier)
                e_mail.Subject = txtSubject.Text
                e_mail.IsBodyHtml = False
                e_mail.Body = txtMessage.Text
                Smtp_Server.Send(e_mail)

            Next

        End If

        MsgBox("Mail Sent")

    Catch error_t As Exception
        MsgBox(error_t.ToString)
    End Try
End Sub

我可以建议使用线程或异步调用来同时发送多封电子邮件吗？
