Unity 3 - Sending Email with C#

Question

I have been looking all over the interwebs for a solution to this problem. I am trying to send an email through Unity and this is the code I currently have:

private void SendEmaill() { // Create a System.Net.Mail.MailMessage object MailMessage message = new MailMessage();

     // Add a recipient
     message.To.Add("curtisgmurray@gmail.com");

     // Add a message subject
     message.Subject = "Email message from Curtis sent by Unity";

     // Add a message body
     message.Body = "Test email";

     // Create a System.Net.Mail.MailAddress object and set the sender email address and display name.
     message.From = new MailAddress("curtisgmurray@gmail.com", "Curtis in Unity");

     // Create a System.Net.Mail.SmtpClient object and set the SMTP host and port number
     SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);


     //smtp.SendAsync(message, "Testing, from Curtis");


     // Create a System.Net.NetworkCredential object and set the username and password required by your SMTP account
     smtp.Credentials = new System.Net.NetworkCredential("curtisgmurray@gmail.com", "JuicyFruit");

     //Enable Secure Socket Layer (SSL) for connection encryption
     smtp.EnableSsl = true;

     // Do not send the DefaultCredentials with requests
     smtp.UseDefaultCredentials = false;        

     // Send the message
     smtp.Send(message); 
 }

The error that Unity 3 is throwing is:

Cannot implicitly convert type System.Net.NetworkCredential' toSystem.Net.ICredentialsByHost'. An explicit conversion exists (are you missing a cast?)

I tried sending an email without using authentication to avoid using this line but gmail requires one to provide authentication. Looking around the web, no one appears to have this issue.

Anyone know what is going on with this bug?

Thanks!

Note: JuicyFruit is not the actual password to my email, I changed it for posting purposes but in my actual code, I have the correct password inputted in.

Try something like

smtp.Credentials = CredentialCache.DefaultNetworkCredentials;

Taken from: http://msdn.microsoft.com/en-us/library/system.net.mail.smtpclient.credentials.aspx

http://msdn.microsoft.com/en-us/library/system.net.credentialcache.aspx

Or if you want to use your own email and password you can try something like this:

NetworkCredential myCred = new NetworkCredential( SecurelyStoredUserName,SecurelyStoredPassword,SecurelyStoredDomain);

CredentialCache myCache = new CredentialCache();

myCache.Add(new Uri("www.contoso.com"), "Basic", myCred);

WebRequest wr = WebRequest.Create("www.contoso.com");
smtp.Credentials = myCache;

Hi there. Thanks for posting up this issue, as it's very helpful for my current project.

This is going to sound probably like a somewhat noobish question, so I apologise in advance.

I've copied your code into a separate C# script and replaced the line:

smtp.Credentials = new System.Net.NetworkCredential("curtisgmurray@gmail.com", "JuicyFruit");

with

smtp.Credentials = (ICredentialsByHost) new System.Net.NetworkCredential("example@gmail.com", "examplePassword");

However when I try to run the script I get two errors. Both related to each other. The first says:

The type or namespace name $$anonymous$$ail$$anonymous$$essage' could not be found. Are you missing a using directive or an assembly reference? the second says: The type or namespace name SmtpClient' could not be found. Are you missing a using directive or an assembly reference?

I looked online and saw that I might need to put the script in my standard assets folder, but that didnt change anything (plus all my scripts are C#). Can anyone help?

I have this working on PC can it be adapted to Android/iOS? I would rather not use the Application.OpenURL method to send email as the user could change the email when sending and my idea is to check the email against the database to ensure it is only sent to who we intend. Any help would be great.
