Question

我正在尝试制作一份反馈表，但之前从未这样做过。我找到了一个在VB中解释它的教程，但即使代码适用于他，它似乎对我没有用。失败后，我尝试了另一个教程，仍然没有去！但由于第一个看起来更简单，我决定再试一次。有些人可以帮我解释一下我做错了什么吗？

我有4个文本框Name，Email，Telephone和Comments

错误似乎是

Dim message As MailMessage = New MailMessage(from, "jaun@bulldogbroadband.co.za", "feedback", body)

错误：指定的字符串不是电子邮件地址所需的格式。

教程：[How Do I:] Create a "Contact Us" Page?

Protected Sub btnSend_Click(sender As Object, e As EventArgs) Handles btnSend.Click
    SendMail(txtName.Text, txtEmail.Text)
    SendMail(txtTel.Text, txtComments.Text)
End Sub
Private Sub SendMail(ByVal from As String, ByVal body As String)
    Dim mailServerName As String = "SMTP.bulldogbroadband.co.za"
    Dim message As MailMessage = New MailMessage(from, "jaun@bulldogbroadband.co.za", "feedback", body)
    Dim mailClient As SmtpClient = New SmtpClient

    mailClient.Host = mailServerName
    mailClient.Send(message)
    message.Dispose()
End Sub

Answer 1

我认为它失败了，因为'from'地址不是有效的电子邮件地址。你也是两次拨打SendMail，第二次用电话号码和评论作为参数。

Answer 2

修正了它，仍然不明白出了什么问题，因为电子邮件地址是有效的，我不知道我是否允许这样做，但我要粘贴我目前正在使用的代码，因为似乎堆栈溢出有非常严格的规则

Imports System.Net.Mail
Imports System.Text
Partial Class ContactUs

Inherits System.Web.UI.Page

Protected Sub btnSend_Click(sender As Object, e As EventArgs) Handles btnSend.Click
    Dim body As String = "From: " + txtName.Text + Environment.NewLine +_
 "Email: " + txtEmail.Text + Environment.NewLine + "Contact Number: " +_
 txtTel.Text + Environment.NewLine + Environment.NewLine + txtComments.Text

    Dim MM As New System.Net.Mail.SmtpClient
    MM.Host = "mail.bulldogbroadband.co.za"
    Dim cred As New System.Net.NetworkCredential("jaun@bulldogbroadband.co.za", "1@2345")
    MM.Credentials = cred
    MM.Send(txtEmail.Text, "jaun@bulldogbroadband.co.za", "feedback form", body)

    Response.Redirect("ThankYou.aspx")

End Sub
