如何在ASP.NET表单中使用gmail SMTP

Question

我是一个ASP新手，正在为工作排查表格故障。我们这里没有人是ASP专家，因为我们使用PHP。但我也在PHP经验的底部，主要是与HTML/CSS单独工作。我当前的表单凭据如下所示：

rotected Sub SubmitForm_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        If Not Page.IsValid Then Exit Sub

        Dim SendResultsTo As String = "email to"
        Dim smtpMailServer As String = "email server"
        Dim smtpUsername As String = "email username"
        Dim smtpPassword As String = "password"
        Dim MailSubject As String = "Form Results"

我该如何将此表单发送到Gmail地址？我知道我必须在某个地方包含port (587)，但是不知道在哪里，因为这个形式与我见过的任何其他形式的语法都不匹配。任何帮助都将不胜感激！

protected void SendMail()
        {
            MailMessage msg = new MailMessage();
            System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient();
            try
            {
                msg.Subject = "Add Subject";
                msg.Body = "Add Email Body Part";
                msg.From = new MailAddress("Valid Email Address");
                msg.To.Add("Valid Email Address");
                msg.IsBodyHtml = true;
                client.Host = "smtp.gmail.com";
                System.Net.NetworkCredential basicauthenticationinfo = new System.Net.NetworkCredential("Valid Email Address", "Password");
                client.Port = int.Parse("587");
                client.EnableSsl = true;
                client.UseDefaultCredentials = false;
                client.Credentials = basicauthenticationinfo;
                client.DeliveryMethod = SmtpDeliveryMethod.Network;
                client.Send(msg);
            }
            catch (Exception ex)
            {
                log.Error(ex.Message);
            }
        }

您可以将其添加到web.config文件中

 <system.net>
    <mailSettings>
      <smtp from="yourMailId@gmail.com ">
        <network host="smtp.gmail.com" defaultCredentials="false"
      port="587" userName ="yourmail@gmail.com" password="yourpassword" />
      </smtp>
    </mailSettings>
   </system.net>

创建System.Net.Mail.SmtpClient对象，设置您正在使用的SMTP服务器信息。

然后用消息数据创建一个System.Smtl.MailMessage并发送它：

using (System.Net.Mail.SmtpClient mail = new System.Net.Mail.SmtpClient()) {
    using (System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage("from*where.com", "to@where.com") {
        IsBodyHtml = true,
        Subject = "Subject text",
        Body = messageBody,
    }) {
        mail.Send(message);
} // using

你可以在构造函数中配置你的SmtpClient，我们使用web.comfig，所以我没有那个代码。
