如何從ASP.Net發送電子郵件

Question

我的問題是我應該使用電子郵件帳戶從asp.net應用程序發送電子郵件，或只是我可以從本地主機發送它？ 問候，

您需要使用System.Net.Mail，和該SmtpClient MAILMESSAGE和對象，像這樣：

using (MailMessage mail = new MailMessage("somebody@foo.com", "someoneelse@bar.com")) 
{ 
    //supply host name and mail port 
    SmtpClient client = new SmtpClient("YourHostName", 25); 

    mail.Subject = "Hello"; 
    mail.Body = "Mail body"; 
    mail.IsBodyHtml = true; 

    client.Send(mail); 
} 

這裏的一類我創建的encompa sses以上：

/// <summary> 
/// Wrapper class for the System.Net.Mail objects 
/// </summary> 
public class SmtpMailMessage : IDisposable 
{ 
    #region declarations 

    MailMessage Message; 
    SmtpClient SmtpMailClient; 

    #endregion 

    #region constructors 

    /// <summary> 
    /// Default constructor for the SmtpMailMessage class 
    /// </summary> 
    public SmtpMailMessage() 
    { 
     //initialize the mail message 
     Message = new MailMessage(); 
     Message.Priority = MailPriority.Normal; 
     Message.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;    
     Message.From = new MailAddress("testperson@foo.com");   

     //initialize the smtp client 
     SmtpMailClient = new SmtpClient(); 
     SmtpMailClient.DeliveryMethod = SmtpDeliveryMethod.Network; 
     SmtpMailClient.Host = "192.168.0.21"; 
     SmtpMailClient.Port = 25; 
    } 

    /// <summary> 
    /// Parameterized constructor for the SmtpMailMessage class. Allows for override of the default 
    /// SMTP host and port number 
    /// </summary> 
    /// <param name="HostIP">The IP address of the exchange server</param> 
    /// <param name="PortNumber">The port number for ingoing and outgoing SMTP messages</param> 
    public SmtpMailMessage(string HostIP, int PortNumber) : this() 
    { 
     //override the smtp host value 
     SmtpMailClient.Host = HostIP; 

     //override the smtp port value 
     SmtpMailClient.Port = PortNumber;
