Be sure to use System.Net.Mail
, not the deprecated System.Web.Mail
. Doing SSL with System.Web.Mail
is a gross mess of hacky extensions.
using System.Net;
using System.Net.Mail;
var fromAddress = new MailAddress("from@gmail.com", "From Name");
var toAddress = new MailAddress("to@example.com", "To Name");
const string fromPassword = "fromPassword";
const string subject = "Subject";
const string body = "Body";
var smtp = new SmtpClient
{
Host = "smtp.gmail.com",
Port = 587,
EnableSsl = true,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
};
using (var message = new MailMessage(fromAddress, toAddress)
{
Subject = subject,
Body = body
})
{
smtp.Send(message);
}
Additionally go to the Google Account > Security page and look at the Signing in to Google > 2-Step Verification setting.
- If it is enabled, then you have to generate a password allowing .NET to bypass the 2-Step Verification. To do this, click on Signing in to Google > App passwords, select app = Mail, and device = Windows Computer, and finally generate the password. Use the generated password in the
fromPassword
constant instead of your standard Gmail password.
- If it is disabled, then you have to turn on Less secure app access, which is not recommended! So better enable the 2-Step verification.
For you to output foo {1, 2, 3}
you have to do something like:
string t = "1, 2, 3";
string v = String.Format(" foo {{{0}}}", t);
To output a {
you use {{
and to output a }
you use }}
.
Or now, you can also use C# string interpolation like this (a feature available in C# 6.0)
Escaping brackets: String interpolation $(""). It is new feature in C# 6.0.
var inVal = "1, 2, 3";
var outVal = $" foo {{{inVal}}}";
// The output will be: foo {1, 2, 3}
