Question

So I wanted to try and send my self some mail using a Visual C# application but it seems to just run through the code (I know this because I put a message box at the end of the code) and not send anything. I did change the email information below for obvious reasons.

Here’s what I have:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net.Mail;
using System.Net;

namespace WindowsFormsApplication9
{
    public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {

    }

    private void button1_Click(object sender, EventArgs e)
    {
        string Host = "smtp.live.com";
        Int16 Port = 587;
        bool SSL = true;
        string Username = "[e-mail]";
        string Password = "mypassword";

        // Mail options
        string To = "[e-mail]";
        string From = "[e-mail]";
        string Subject = "This is a test";
        string Body = "It works!";

        MailMessage mm = new MailMessage(From, To, Subject, Body);
        SmtpClient sc = new SmtpClient(Host, Port);
        NetworkCredential netCred = new NetworkCredential(Username, Password);
        sc.EnableSsl = SSL;
        sc.UseDefaultCredentials = false;
        sc.Credentials = netCred;

        MessageBox.Show("Test");
    }
}
}

*Note, I get NO errors from this.

You don’t actually send the mail.

Add this to your code – you should be able to figure out where:

sc.Credentials = netCred;

try 
{
  sc.Send(message);
}  
catch (Exception ex) 
{
  MessageBox(ex.ToString());              
}              
MessageBox.Show("Test");
