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

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>

        <table>             
            <tr> 
                <td  style="align-items:center"> 
                    Name:</td> 
                <td>

            </tr> 
 
 
 
            <!-- Message --> 
            <tr> 
                <td style="align-items:center"> 
                    What are you looking for?

                        onclick="btnSubmit_Click" /><br />

                </td> 
            </tr> 
        </table> 

这是后面的代码；

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Net; 
using System.Net.Mail; 
using System.Web; 
using System.Web.UI; 
using System.Web.UI.WebControls; 
 
public partial class Telluswhatyouwant : System.Web.UI.Page 
{ 
    protected void Page_Load(object sender, EventArgs e) 
    { 
 
    } 
    protected void btnSubmit_Click(object sender, EventArgs e) 
    { 
 
        try 
        { 
            //Create the msg object to be sent 
            MailMessage msg = new MailMessage(); 
            //Add your email address to the recipients 
            msg.To.Add("ronan.byrne@mhlabs.net"); 
 
//Send the msg 
            client.Send(msg); 

请您参考如下方法:

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; 
    }
