试图用C＃发送邮件，但它似乎没有工作

Question

所以我想尝试使用Visual C＃应用程序发送自己的一些邮件，但它似乎只是通过代码运行（我知道这是因为我把代码末尾的消息框）并且不发送任何内容。我确实更改了以下电子邮件信息，原因很明显。

这是我有：

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 = "[email protected]"; 
     string Password = "mypassword"; 

     // Mail options 
     string To = "[email protected]"; 
     string From = "[email protected]"; 
     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"); 
    } 
} 
} 

*注意，我从中得到任何错误。

Answer 1

你实际上并没有发送邮件。

添加到您的代码 - 你应该能够找出其中：

sc.Credentials = netCred; 

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

Answer 2

添加这些命名空间...

using System.Net.Mail; 
using System.Net; 
using System.Configuration; 

添加以下代码行的代码隐藏文件您想在哪里发送电子邮件。

System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage("yourEmailId", "destinationEmailId"); 
mail.Subject = ""; //Enter the text for the subject of the mail in quotes. 
mail.Body = ""; //Enter the text for the body of mail within the quotes. 
mail.IsBodyHtml = true; 
SmtpClient client = new SmtpClient("smtp.live.com"); 
NetworkCredential cred = new NetworkCredential("yourEmailId", "yourPassword"); 
client.EnableSsl = true; 
client.Credentials = cred; 
try 
{ 
client.Send(mail); 
} 
catch (Exception) 
{ 
}
