Question

我想从.NET中的服务器向我的邮件发送一封虚拟邮件。

我只是在没有操纵的情况下发送邮件：请让我知道我哪里出错了。我编写了如下代码：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="SendingEmail.aspx.cs" Inherits="experiments_asp_SendingEmail" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>

 <form id="form1" runat="server">
<h2>Send e-mail to someone@example.com:</h2>
<asp:Button Text="Submit" OnClick="sendMail" runat="server"/>
</form>

</body>
</html>

我的.Net代码如下所示：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net.Mail;
public partial class experiments_asp_SendingEmail : System.Web.UI.Page
{
    protected void sendMail(object sender, EventArgs e)
    {
        Console.Write("came here");
        CreateTestMessage2("my college server"); //
    }
    public static void CreateTestMessage2(string server)
    {
        string to = "xyz@gmail.com";
        string from = "xyz@gmail.com";
        MailMessage message = new MailMessage(from, to);
        message.Subject = "Using the new SMTP client.";
        message.Body = @"Using this new feature, you can send an e-mail message from an application very easily.";
        SmtpClient client = new SmtpClient(server);       
        client.UseDefaultCredentials = true;

        try
        {
            client.Send(message);
        }
        catch (Exception ex)
        {
            Console.WriteLine("Exception caught in CreateTestMessage2(): {0}",
                  ex.ToString());
        }
    }
}

如果此代码中有任何问题，请告诉我，我是否需要添加任何额外的内容。

点击提交后，我没有收到任何错误。

期望：发送虚拟邮件。请注意我是＆lt;

我认为您需要向SMTP服务器提供更多信息才能接受您的请求。让我们以Gmail为例。我已经使用了您的代码并使其能够从google smtp服务器分发电子邮件：

string to = "xyz@gmail.com";
string from = "xyz@gmail.com";
MailMessage message = new MailMessage(from, to);
message.Subject = "Using the new SMTP client.";
message.Body = @"Using this new feature, you can send an e-mail message from an application very easily.";
SmtpClient client = new SmtpClient("smtp.gmail.com", 587);
client.EnableSsl = true;
client.UseDefaultCredentials = true;

NetworkCredential nc = new NetworkCredential("yourEmail@gmail.com", "yourPassword");
client.Credentials = nc;

try
{
    client.Send(message);
    MessageBox.Show("Your message was sent.");
}
catch (Exception ex)
{
    Console.WriteLine("Exception caught in CreateTestMessage2(): {0}",
          ex.ToString());
}

如您所见，您需要指定smtp服务器正在侦听的活动端口，并允许SSL消息传输。另一个关键部分是提供可接受的凭据，SMTP服务器可以验证用户进行身份验证。也许你的大学服务器有类似的架构。你管理服务器还是其他人？
