c# - 邮件程序问题：处理您的请求时发生错误。ASP.NET MVC 5

问题描述

如果我使用这个邮件方法，我会得到如下所示的错误：

处理您的请求时发生错误

这是我在控制器 ActionResult 中使用的邮件方法。

   private void SendActivationEmail(string activationCodes, string emailid, string Fullname)
    {
        MailAddress from = new MailAddress(System.Configuration.ConfigurationManager.AppSettings["AdminFromEmailAddress"].ToString());
        MailAddress to = new MailAddress(emailid);
        MailMessage message = new MailMessage(from, to);
        string LinkPath = System.Configuration.ConfigurationManager.AppSettings["verifyuserpath"].ToString();
        message.IsBodyHtml = true;
        string strBody;
        int a = 0;
        strBody = "";
        strBody = strBody + "Dear" + " " + Fullname + "," + "<br><br>";
        strBody = strBody + "Thank you for your interest in the testing Program." + "<br><br>";
        strBody = strBody + "Please click <a href=" + LinkPath + "Registers/IAActivation?emailId=" + emailid + "&uCode=" + activationCodes + "&type=" + a + ">here</a> to finish setting up this testing account, we just need to make sure this email address is yours  or paste the following link into your browse" + "<br><br>";
        strBody = strBody + "<a href=" + LinkPath + "Registers/IAActivation?emailId=" + emailid + "&uCode=" + activationCodes + "&type=" + a + ">" + LinkPath + "Registers/IAActivation?emailId=" + emailid + "&uCode=" + activationCodes + "&type=" + a + "" + "</a><br><br>";
        strBody = strBody + "<br>With Regards" + "," + "<br>";
        strBody = strBody + "testing Team";
        message.Subject = "Verification Mail";
        message.Body = strBody;
        SmtpClient client = new SmtpClient(System.Configuration.ConfigurationManager.AppSettings["SmtpClientclientPath"].ToString());
        client.Port = Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["SmtpClientclientPathPort"].ToString());
        client.Send(message);
   }

这是我从 web.config 邮件程序路径调用的应用程序设置。

<appSettings>
    <add key="webpages:Version" value="3.0.0.0" />
    <add key="webpages:Enabled" value="false" />
    <add key="ClientValidationEnabled" value="true" />
    <add key="UnobtrusiveJavaScriptEnabled" value="true" />

    <add key="AdminFromEmailAddress" value="info@xyz.in" />
    <add key="SmtpClientclientPath" value="000.0.0.1" /> 
    <add key="SmtpClientclientPathPort" value="25" />
    <!-- Your SMTP Server IP  -->
    <add key="gmailHost" value="smtp.gmail.com" />
    <add key="userName" value="techhelp@xyz.in" />
    <add key="password" value="tech@123" />
    <add key="gmailport" value="587" />
    <add key="verifyuserpath" value="http://xyz.in/" />
</appSettings>

如果我注释掉这一行 

client.Send(message);

在邮件方法中，然后注册提交工作但邮件不去。

实际上，我是 asp.net mvc5 的新手，但我声明的邮件路径与 Web 表单一样。请帮我解决这个邮件问题。而且我没有发布我的mvc5项目直接将所有文件上传到live没有发布。

解决方案

您可以构建您的 SmtpClient 如下所示：

SmtpClient client = new SmtpClient
{
    Host = "smtp.gmail.com",
    Port = 587,
    EnableSsl = true,
    DeliveryMethod = SmtpDeliveryMethod.Network,
    Credentials = new NetworkCredential("fromAddress", "fromPassword"),
    Timeout = 20000
};

替换 FromAddress 和密码。

注意：不要忘记在您的 Google 帐户安全设置中启用“允许不太安全的应用程序” 。
