无法在 asp.net vb 网站中发送电子邮件

Question

当我填写联系表格时，页面会重新加载，并且没有邮件发送到收件人邮箱。

但我也希望当用户按下发送按钮时，一封电子邮件被发送到收件人，那里会弹出一个消息框，其中包含如下文本："a copy was sended to your email"

ASP.NETvb背后的代码


    Imports System.Net
    Imports System.Net.Mail

Protected Sub btnSend_Click(ByVal sender As Object, ByVal e As EventArgs)
        Dim Message As MailMessage = New MailMessage()
        Dim Smtp As New SmtpClient()

        Dim SmtpUser As New System.Net.NetworkCredential()


        Message.From = New MailAddress("sender@domain.be", "Van voorbeeld")
        Message.To.Add(New MailAddress("receiver@domain.be", "Naar voorbeeld"))
        Message.IsBodyHtml = False



        Message.Subject = "Nefsani Contact Form"
        Message.Body = "Email: " & Qemail.Text & Environment.NewLine & "Phone: " & QTel.Text & Environment.NewLine & "Question: " & Qmessage.Text



        SmtpUser.UserName = "sender@domain.be"
        SmtpUser.Password = "Password"



        Smtp.UseDefaultCredentials = False
        Smtp.Credentials = SmtpUser
        Smtp.Host = "smtp.mijnhostingpartner.nl"
        Smtp.DeliveryMethod = SmtpDeliveryMethod.Network
        Smtp.Send(Message)
    End Sub

aspx 文件中的代码

<div class="col-md-3 col-sm-6 footer-widget">
                    <h4>Contacteer mij</h4>
                    <ul>                      
                        <asp:TextBox ID="QFullname" class="form-control" placeholder="Naam + Voornaam" alt="Naam + Voornaam " runat="server"></asp:TextBox><br >

            <div class="col-md-3 col-sm-6 footer-widget">
            <div class="contact-footer">

                    <asp:TextBox style="margin-top:52px" id="Qmessage" class="form-control" rows="4" TextMode="multiline" placeholder="Schrijf hier uw bericht." alt="Schrijf hier uw bericht." runat="server" />
                       <br><br/>
                    <asp:Button ID="btnSend" style="margin-top:-40px" class="btn btn-primary" runat="server" Text="Verzend" />
                    <asp:Label id="lblMessage" runat="server"></asp:Label>
                </ul>
           </div>`enter code here`
            </div>

Answer 1

你什么也没得到的原因是你的按钮没有绑定到你的点击功能。您要么必须向按钮添加一个 onclick，要么必须向您的函数添加一个 handles 事件。

  <asp:Button ID="btnSend" style="margin-top:-40px" class="btn btn-primary" runat="server" Text="Verzend" onclick="btnSend_Click" />

或

Protected Sub btnSend_Click(ByVal sender As Object, ByVal e As EventArgs) handles btnSend.Click

关于在点击处理程序底部显示消息：

lblMessage.Text = "a copy was sended to your email"
