c# - 在 asp.net 中使用 smtp 和 gmail 提交表单后发送电子邮件

Question

当我的表单在我的网页上提交后，我正在尝试接收一封电子邮件。目前它提交正常，没有任何错误，但我没有收到电子邮件。有谁知道我必须在代码隐藏页面中添加什么代码才能使这项工作正常进行？

这是html;

<h2>Contact Us</h2>
        <br />
        <table>            
            <tr>
                <td  style="align-items:center">
                    Name:</td>
                <td>
                    <asp:TextBox ID="txtName"
                                    runat="server"
                                    Columns="40"></asp:TextBox>

            MailMessage msg = new MailMessage();
            //Add your email address to the recipients
            msg.To.Add("ronan.byrne@mhlabs.net");

//Send the msg
            client.Send(msg);

这是启用邮件选项的本地主机的完美工作代码。您可以更改端口号。fromWho、toWho 是字符串格式的邮寄地址(即:david@yahoo.com)

    string sMailServer = "127.0.0.1";

    MailMessage MyMail = new MailMessage();
    MyMail.From = fromWho;
    MyMail.To = toWho;
    if (toCC != "" || toCC != null)
    {
        MyMail.Cc = toCC;
    }
    if (toBCC != "" || toBCC != null)
    {
        MyMail.Bcc = toBCC;
    }

    MyMail.Subject = Subject;
    MyMail.Body = Body;
    //MyMail.BodyEncoding = Encoding.UTF8;
    MyMail.BodyFormat = MailFormat.Html;

    SmtpMail.SmtpServer = sMailServer;
    try
    {

        SmtpMail.Send(MyMail);


    }
    catch (Exception ex)
    {
        return ex;
    }
