如何用C＃中的姓名發送多個電子郵件地址

Question

如何用C＃中的姓名發送多個電子郵件地址？目前我需要從數據庫加載名稱和電子郵件地址併發送它。

1. 所以我應該創建一個字符串數組來存儲名稱和電子郵件地址？

2. 那麼我該如何發送電子郵件？必須將MailMessages（）或MailAddress用於多個郵件地址？

我的代碼

while (sdrReader.Read()) 
{  
    ReceiverName = sdrReader["Name"].ToString(); 
    ReceiverEmail = sdrReader["EmailAddress"].ToString();   
} 

//郵件添加，在這裏我想要得到的多個電子郵件名稱和地址，然後發送。

mail.To.Add(new MailAddress(ReceiverEmail, ReceiverName)); 



sSQL = @"SELECT * FROM EmailSystem"; 

      try 
      { 
       scConnection.Open(); 
       scCommand = new SqlCommand(sSQL, scConnection); 
       sdrReader = scCommand.ExecuteReader(); 

       while (sdrReader.Read()) 
       { 

         ReceiverName = sdrReader["Name"].ToString(); 
         ReceiverEmail = sdrReader["EmailAddress"].ToString(); 

       } 
      } 



try 
      { 
       // Instance of Mail Server 
       MailMessage mail = new MailMessage(); 

       // Instance of SMTP Server 
       SmtpClient server = new SmtpClient(smtpAddress); 


       mail.To.Add(new MailAddress(ReceiverEmail, ReceiverName));    
      }

這是你可能會爲了實現自己的目標使用的草圖。我沒有觸及數據庫連接，我希望你檢查了你可以從數據庫中讀取數據。如果你有更多的問題，請不要猶豫。

// define the body of your mail 
var message = new MailMessage 
{ 
    From = new MailAddress("foo@gmail.com", "John Doe"), 
    Subject = "Please don't spam me", 
    Body = "I will be very angry if you send me spam." 
}; 

// if you don't use gmail, then you have to specify your own settings!!! 
var client = new SmtpClient("smtp.gmail.com", 587) 
{ 
    EnableSsl = true, 
    Credentials = new NetworkCredential("foo@gmail.com", "superPassword") 
}; 

// I skipped the creation of connection and command. 
// Don't forget to call Dispose when you finish to work with database. 
while (sdrReader.Read()) 
{ 
    var to = new MailAddress(sdrReader["EmailAddress"].ToString(), 
          sdrReader["Name"].ToString()); 
    message.To.Add(to); 
} 

client.Send(message);

您可以自動運行Microsoft Outlook以編程方式發送電子郵件。有關更多信息，請參閱Using Automation to Send a Microsoft Outlook Message。

使用數據集或數據表來代替數據讀取器，併爲每個數據迭代值。
