wie E-Mail Bulk-Liste zu Adresse hinzufügen, die von Dataset mit sparkpost

Question

Ich versuche, Bulk-Mail-Liste zu Adressen hinzufügen, so dass ich diese Bulk-Mail-Liste zu einer Zeit senden kann.Hier habe ich dies durch Schleifen in jeden Datensatz getan dass kehrte von meinem dataset.Is es eine bessere Art und Weise, dass die Gesamtdatenmenge ohne looping.Thanks der Adressliste hinzuzufügen, in advance.Here mein Code

DataSet ds = new DataSet(); 

List<string> to = new List<string>(); 

//I have returned one dataset containing list of emails to be send. 

ds = email.GetBulkProcessMails("Process"); 

//here I am looping through every record in the dataset and adding that records to my List 

if (ds.Tables.Count > 0) 
      { 

       foreach (DataRow dtrow in ds.Tables[0].Rows) 
       { 
        tomailscount bmscount = new tomailscount(); 
        bmscount.destinationmails = dtrow["tomail_id"].ToString(); 
        to.Add(bmscount.destinationmails.ToString()); 
       } 
      } 


//Here I am assigning that entire list to address and adding that recipient for transmission 
    for (int i = 0; i < to.Count; i++) 
      { 
       var recipient = new Recipient 
       { 

        Address = new Address { Email = to[i] } 

       }; 
       transmission.Recipients.Add(recipient); 
      } 


//Here I am sending that transmission 

var sparky = new Client(ConfigurationManager.AppSettings["APIKey"]); 
sparky.Transmissions.Send(transmission);

Sie eine Schleife entfernen können, und gerade dies zu tun:

if (ds.Tables.Count > 0) 
{ 

    foreach (DataRow dtrow in ds.Tables[0].Rows) 
    { 
     tomailscount bmscount = new tomailscount(); 
     bmscount.destinationmails = dtrow["tomail_id"].ToString(); 
     to.Add(bmscount.destinationmails.ToString()); 
     transmission.Recipients.Add(new Recipient { 
      Address = new Address { Email = bmscount.destinationmails.ToString() } 
     }); 
    } 

    // send it 
    var sparky = new Client(ConfigurationManager.AppSettings["APIKey"]); 
    sparky.Transmissions.Send(transmission); 
}
