我正在使用ASP.NET mvc 4.我正嘗試使用smtp客戶端發送電子郵件。我現在正在使用localhost。但是，我的代碼會拋出「無法連接到遠程服務器「。任何人都可以幫助我，我做錯了什麼？Asp.net mvc 4發送電子郵件
我的代碼：
using System.Net.Mail;
using System.Net.Mime
MailMessage msg = new MailMessage();
SmtpClient client = new SmtpClient();
try
{
msg.From = new MailAddress("[email protected]", "Display name");
msg.To.Add("[email protected]");
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("[email protected]", "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";
}
