i wrote code to send emails to user from my application , i put TO, CC and Subject textboxes in which i mention Recepients but problem is that i can only mention 1 recepient in To and CC fields, i am just wondering that how to add multiple reciepient, like in Outlook we mention multiple recepients like with colon e.g.

user1@yahoo.com; user2@hotmail.com; user3@gmail.com; ........................

same in CC

i have a simple text box TO in which i can put 1 address

how to do that ?

CODE:

<pre lang="c#">using System.Net.Mail;
using System.Net;
using Outlook = Microsoft.Office.Interop.Outlook;

public ActionResult dailyLog(String txtEmailTo, String txtCC, String txtSubject, String txtBody) 
        {
            if (!String.IsNullOrEmpty(Session["Admin"] as string))
            {
                try
                {
                    Outlook.Application oApp = new Outlook.Application();
                    Outlook.MailItem oMsg = (Outlook.MailItem)oApp.CreateItem(Outlook.OlItemType.olMailItem);
                    oMsg.HTMLBody = txtBody;
                    //Add an attachment.
                    //String sDisplayName = "MyAttachment";
                    int iPosition = (int)oMsg.Body.Length + 1;
                    //int iAttachType = (int)Outlook.OlAttachmentType.olByValue;
                    //now attached the file
                    //Outlook.Attachment oAttach = oMsg.Attachments.Add(@"C:\\fileName.jpg", iAttachType, iPosition, sDisplayName);
                    //Subject line
                    oMsg.Subject = txtSubject;
                    // Add a recipient.
                    Outlook.Recipients oRecips = (Outlook.Recipients)oMsg.Recipients;
                    Outlook.Recipient oRecip = (Outlook.Recipient)oRecips.Add(txtEmailTo);
                    oRecip = oRecips.Add(txtCC);
                    oRecip.Type = (int)Outlook.OlMailRecipientType.olCC;
                    oRecip.Resolve();
                    // Send.
                    oMsg.Send();
                    // Clean up.
                    oRecip = null;
                    oRecips = null;
                    oMsg = null;
                    oApp = null;
                    ViewBag.Confirmation = "Daily Has Been Log Submitted";
                    return View();
                }
                catch (Exception ex)
                {
                    ViewBag.Confirmation = ex.Message;
                    return View();
                }
            }
