I can't understand why this code is not working. I get an error saying property can not be assigned
MailMessage mail = new MailMessage();
SmtpClient client = new SmtpClient();
client.Port = 25;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Host = "smtp.gmail.com";
mail.To = "user#hotmail.com"; // <-- this one
mail.From = "you#yourcompany.example";
mail.Subject = "this is a test email.";
mail.Body = "this is my test email body";
client.Send(mail);
mail.To and mail.From are readonly. Move them to the constructor.
using System.Net.Mail;
...
MailMessage mail = new MailMessage("you#yourcompany.example", "user#hotmail.com");
SmtpClient client = new SmtpClient();
client.Port = 25;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Host = "smtp.gmail.com";
mail.Subject = "this is a test email.";
mail.Body = "this is my test email body";
client.Send(mail);
This :
mail.To = "user#hotmail.com";
Should be:
mail.To.Add(new MailAddress("user#hotmail.com"));
Finally got working :)
using System.Net.Mail;
using System.Text;
...
// Command line argument must the the SMTP host.
SmtpClient client = new SmtpClient();
client.Port = 587;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
client.Timeout = 10000;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("user#gmail.com","password");
MailMessage mm = new MailMessage("donotreply#domain.example", "sendtomyemail#domain.example", "test", "test");
mm.BodyEncoding = UTF8Encoding.UTF8;
mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
client.Send(mm);
sorry about poor spelling before
public static void SendMail(MailMessage Message)
{
SmtpClient client = new SmtpClient();
client.Host = "smtp.googlemail.com";
client.Port = 587;
client.UseDefaultCredentials = false;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.EnableSsl = true;
client.Credentials = new NetworkCredential("myemail#gmail.com", "password");
client.Send(Message);
}
This is how it works for me. Hope you find it useful
MailMessage objeto_mail = new MailMessage();
SmtpClient client = new SmtpClient();
client.Port = 25;
client.Host = "smtp.internal.mycompany.com";
client.Timeout = 10000;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("user", "Password");
objeto_mail.From = new MailAddress("from#server.com");
objeto_mail.To.Add(new MailAddress("to#server.com"));
objeto_mail.Subject = "Password Recover";
objeto_mail.Body = "Message";
client.Send(objeto_mail);
First go to https://myaccount.google.com/lesssecureapps and make Allow less secure apps true.
Then use the below code. This below code will work only if your from email address is from gmail.
static void SendEmail()
{
string mailBodyhtml =
"<p>some text here</p>";
var msg = new MailMessage("from#gmail.com", "to1#gmail.com", "Hello", mailBodyhtml);
msg.To.Add("to2#gmail.com");
msg.IsBodyHtml = true;
var smtpClient = new SmtpClient("smtp.gmail.com", 587); //**if your from email address is "from#hotmail.com" then host should be "smtp.hotmail.com"**
smtpClient.UseDefaultCredentials = true;
smtpClient.Credentials = new NetworkCredential("from#gmail.com", "password");
smtpClient.EnableSsl = true;
smtpClient.Send(msg);
Console.WriteLine("Email Sent Successfully");
}
If you want to have your email and password not appear in your code and want your company email client server to use your windows credentials use below.
client.Credentials = CredentialCache.DefaultNetworkCredentials;

This just worked for me as of March 2017.
Started with solution from above "Finally got working :)" which didn't work at first.
SmtpClient client = new SmtpClient();
client.Port = 587;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
client.Timeout = 10000;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("<me>#gmail.com", "<my pw>");
MailMessage mm = new MailMessage(from_addr_text, to_addr_text, msg_subject, msg_body);
mm.BodyEncoding = UTF8Encoding.UTF8;
mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
client.Send(mm);

Just need to try this:

int portNumber = 587;
bool enableSSL = true;
string emailFrom = "companyemail";
string password = "password";
string emailTo = "Your email";
string subject = "Hello!";
string body = "Hello, Mr.";
MailMessage mail = new MailMessage();
mail.From = new MailAddress(emailFrom);
mail.To.Add(emailTo);
mail.Subject = subject;
mail.Body = body;
mail.IsBodyHtml = true;
using (SmtpClient smtp = new SmtpClient(smtpAddress, portNumber))
{
smtp.Credentials = new NetworkCredential(emailFrom, password);
smtp.EnableSsl = enableSSL;
smtp.Send(mail);
}
MailKit is an Open Source cross-platform .NET mail-client library that is based on MimeKit and optimized for mobile devices.
It has more and advance features better than System.Net.Mail
Microsoft TNEF support via MimeKit.
Download nuget package from here.
See this example you can send mail
MimeMessage mailMessage = new MimeMessage();
mailMessage.From.Add(new MailboxAddress(senderName, sender#address.com));
mailMessage.Sender = new MailboxAddress(senderName, sender#address.com);
mailMessage.To.Add(new MailboxAddress(emailid, emailid));
mailMessage.Subject = subject;
mailMessage.ReplyTo.Add(new MailboxAddress(replyToAddress));
mailMessage.Subject = subject;
var builder = new BodyBuilder();
builder.TextBody = "Hello There";
try
{
using (var smtpClient = new SmtpClient())
{
smtpClient.Connect("HostName", "Port", MailKit.Security.SecureSocketOptions.None);
smtpClient.Authenticate("user#name.com", "password");
smtpClient.Send(mailMessage);
Console.WriteLine("Success");
}
}
catch (SmtpCommandException ex)
{
Console.WriteLine(ex.ToString());
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
Initialize the MailMessage with sender and reciever's email addresses. It should be something like
string from = "codeforwin#gmail.com"; //Senders email
string to = "reciever#gmail.com"; //Receiver's email
MailMessage msg = new MailMessage(from, to);

this would work too..

string your_password = "password";

I have this MVC C# App and a controller where trying to send a email, but I always got this error
this is the code in my action´controller, it doesn´t receive any model so I add specific values
[HttpPost]
public ActionResult Index2()
{
try
{
MailMessage mail = new MailMessage();
mail.To.Add("valid_email#hotmail.com");
mail.From = new MailAddress("valid_email#gmail.com");
mail.Subject = "PruebaMVC";
string Body = "PruebaMVC";
mail.Body = Body;
mail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.UseDefaultCredentials = false;
smtp.Credentials = new System.Net.NetworkCredential
("valid_email#gmail.com", "correctPWD");
smtp.EnableSsl = true;
smtp.Send(mail);
}
catch (Exception ex)
{
throw new ArgumentNullException("Exception in sendEmail:" + ex.Message);
}
return View();
}
could you please tell what is wrong?
edit: this is the exception I got
As i have used below code and it's working fine for me and i have configured smtp in web.config
ContentType HTMLType = new ContentType("text/html");

msg.Subject = Subj;
msg.Body = strBody;
msg.IsBodyHtml = true;
if (attachement != null)
{
msg.Attachments.Add(attachement);
}
System.Net.Mail.AlternateView HTMLView = System.Net.Mail.AlternateView.CreateAlternateViewFromString(strBody, HTMLType);
msg.From = new MailAddress(StringConstant.MailFrom); // Your Email Id
SmtpClient client = new SmtpClient(StringConstant.SmtpFrom, StringConstant.SmtpPort);
client.Credentials = cred;
client.EnableSsl = true;
client.Send(msg);
I have this aspx function which send email. Unfortunetely, it does not render html tag on gmail or outlook, but on my android phone looks fine. How to fix it? thanks.

EDITED:
So here is what i have now. But the compiler gives this error:

mail.From = fromAddress;
mail.To = toAddress;
mail.Subject = subject;
mail.IsBodyHtml = true;
mail.Body = body;

My working solution:
using System.Net;
using System.Net.Mail;
using System.Net.Mime;
var fromAddress = "****"; // mail Address from where you send the mail
var toAddress = "****";
const string fromPassword = "***"; //Password of your gmail address
var subject = "New Job Created!";
// set smtp-client with basicAuthentication
SmtpClient mySmtpClient = new SmtpClient("smtp.gmail.com");
mySmtpClient.Port = 587;
mySmtpClient.EnableSsl = true;
mySmtpClient.UseDefaultCredentials = false;
System.Net.NetworkCredential basicAuthenticationInfo = new
System.Net.NetworkCredential(fromAddress, fromPassword);
mySmtpClient.Credentials = basicAuthenticationInfo;
// add from,to mailaddresses
MailAddress from = new MailAddress(fromAddress, "");
MailAddress to = new MailAddress(toAddress, "Devision");
MailMessage myMail = new System.Net.Mail.MailMessage(from, to);
// set subject and encoding
myMail.Subject = subject;
myMail.SubjectEncoding = System.Text.Encoding.UTF8;

myMail.Body = "<b>TEST</b>";
myMail.BodyEncoding = System.Text.Encoding.UTF8;
// text or html
myMail.IsBodyHtml = true;
mySmtpClient.Send(myMail);
Create MailMessage Class. The key thing is to specify that the Body of the is HTML this is done with property IsBodyHtml
MailMessage mail= new MailMessage();
mail.From = fromAddress;
mail.To = toAddress;
mail.Subject = subject;
mail.IsBodyHtml = true;
mail.Body = body;

Here is working code to send an email to gmail smtp. From what I see you don't set UseDefaultCredentials = false and you are using wrong port. Also you MUST NOT override exceptions like this., throw the initial exception. Also for this to work you need to turn off security setting in your Gmail account. You can google it.
i am sending single mail to more than 1 person. so i am sending mail in for loop with attachement.but while in second loop i am getting file lock error.below is my code.
public string SendMail(string toList, string from, string ccList,
string subject, string body)
{
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
SmtpClient smtpClient = new SmtpClient();
string msg = string.Empty;
try
{
MailAddress fromAddress = new MailAddress(from);
message.From = fromAddress;
message.To.Add(toList);
if (ccList != null && ccList != string.Empty)
message.CC.Add(ccList);
message.Subject = subject;
message.IsBodyHtml = true;
message.Body = body;
// We use gmail as our smtp client
smtpClient.Host = "smtp.gmail.com";
smtpClient.Port = 587;
smtpClient.EnableSsl = true;
smtpClient.UseDefaultCredentials = true;
smtpClient.Credentials = new System.Net.NetworkCredential(TextBox1.Text, TextBox2.Text);
if (FileUpload2.HasFile)
{
// File Upload path
String FileName = FileUpload2.PostedFile.FileName;
FileUpload2.PostedFile.SaveAs(Server.MapPath(FileName));
//Getting Attachment file
Attachment mailAttachment = new Attachment(Server.MapPath(FileName));
//Attaching uploaded file
message.Attachments.Add(mailAttachment);
}
smtpClient.Send(message);
LblMessage.ForeColor = System.Drawing.Color.Green;
LblMessage.Text = "Mail Sent Successfully.";
}
catch (Exception ex)
{
LblMessage.Text = ex.Message;
LblMessage.ForeColor = System.Drawing.Color.Red;
}
return msg;
}
in loop calling this function
for (int i = 0; i < LbEmails.Items.Count; i++)
{
SendMail(LbEmails.Items[i].ToString(), TextBox1.Text, "", TbSubject.Text, TbBody.Text);
}
It looks like you're saving the uploaded file once for each email you send even though it seems to be the same for all the emails. Pull this line out of the SendMail() method and call it before your loop:
FileUpload2.PostedFile.SaveAs(Server.MapPath(FileName));
