我正在使用ASP.NET mvc 4.我正在尝试使用smtp client发送电子邮件。我现在正在使用localhost。但是，我的代码会抛出“无法连接到远程服务器”的错误。任何人都可以帮我解决我做错的事吗？
我的代码：
using System.Net.Mail;
using System.Net.Mime
MailMessage msg = new MailMessage();
SmtpClient client = new SmtpClient();
try
{
msg.From = new MailAddress("from@gmail.com", "Display name");
msg.To.Add("rt@gmail.com");
msg.Subject = "Password";
msg.Body = "This is the test";
msg.Priority = MailPriority.High;
msg.IsBodyHtml = true;
//the actual email and to send the picture in the image.........
// return "reached here";
string str = "<html><body><h1>picture</h1></br></body></html>";
AlternateView av = AlternateView.CreateAlternateViewFromString(str, null, MediaTypeNames.Text.Html);
// LinkedResource lr = new LinkedResource("C:/RANJAN'S/PROJECTS/Darn/Darn_3/darnCoupon/darnCoupon/Images/Carousel/carousel_1.jpg", MediaTypeNames.Image.Jpeg);
// lr.ContentId = "image1";
// av.LinkedResources.Add(lr);
msg.AlternateViews.Add(av);
client.Host = "smtp.gmail.com";
client.Port = 587;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.Credentials = new System.Net.NetworkCredential("rp@gmail.com", "Password");
client.UseDefaultCredentials = false;
client.EnableSsl = true;
client.Send(msg);
return "reached here toooooooo";
// return msg.ToString();
}
catch (Exception ex)
{
return ex.InnerException.Message;
}
return "nothing happpened";
}

我建议你从这里下载并安装Smtp4Dev（http://smtp4dev.codeplex.com/）。安装完成后，无论您使用smtp服务器设置，都可以判断邮件是否已发送。一旦确定问题的根源不是您的代码，那么您就可以看到smtp服务器设置发生了什么。

试试这段代码。我希望它能像你期望的那样发挥作用。
SmtpClient client = new SmtpClient();
MailMessage msg = new MailMessage();
MailAddress to = new MailAddress("client email address");
MailAddress from = new MailAddress("Your Email Address");
msg.IsBodyHtml = true;
msg.Subject = "Mail Title";
msg.To.Add(to);
msg.Body = "Your message";
msg.From = from;
client.Send(msg);
在配置部分下的web.config文件中，您需要编写邮件帐户的凭据信息
<system.net>
<mailSettings>
<smtp deliveryMethod="Network">
<network host="smtp.gmail.com" port="587" userName="your email address" password="your password" defaultCredentials="false" enableSsl="true" />
</smtp>
</mailSettings>
</system.net>
