C# to Send Mail using Outlook

I'm working in console Application and I'm using the below c# code to send mail automatically on a button click event,

    public void SendMail()
    {
        //// Create the Outlook application by using inline initialization.
        Outlook.Application oApp = new Outlook.Application();

        ////Create the new message by using the simplest approach.
        Outlook.MailItem oMsg = (Outlook.MailItem)oApp.CreateItem(Outlook.OlItemType.olMailItem);

        //Add a recipient.
        // TODO: Change the following recipient where appropriate.
        Outlook.Recipients oRecips = oMsg.Recipients;
        List<string> oTORecip = new List<string>();
        List<string> oCCRecip = new List<string>();

        oTORecip.Add("[email protected]");
        oCCRecip.Add("[email protected]");
        foreach (string t in oTORecip)
        {
            Outlook.Recipient oTORecipt = oRecips.Add(t);
            oTORecipt.Type = (int)Outlook.OlMailRecipientType.olTo;
            oTORecipt.Resolve();
        }

        foreach (string t in oCCRecip)
        {
            Outlook.Recipient oCCRecipt = oRecips.Add(t);
            oCCRecipt.Type = (int)Outlook.OlMailRecipientType.olCC;
            oCCRecipt.Resolve();
        }

        //Set the basic properties.
        oMsg.Subject = "TestMail- " + DateTime.Today.ToString("MM/dd/yyyy");
        oMsg.HTMLBody = "<html>" +
            "<head>" +
            "<title>TestMail</title>" +
            "</head>" +
            "<body style='background-color:#E6E6E6;'>" +
            "<div style='font-family: Georgia, Arial; font-size:14px; '>Hi,<br /><br />" +
            "PFA<br />" +
            "This is Test Mail.Please Ignore.<br /><br /><br /><br /><br />" +
            "Thanks & Regards<br />" +
            "test"+
            "</div>" +
            "</body>" +
            "</html>";
        string date = DateTime.Today.ToString("MM-dd-yyyy");

        //Add an attachment.
        // TODO: change file path where appropriate
        String sSource = "D:\\Test\\test_" + date + ".xlsx";
        String sDisplayName = "MyFirstAttachment";
        int iPosition = (int)oMsg.Body.Length + 1;
        int iAttachType = (int)Outlook.OlAttachmentType.olByValue;
        Outlook.Attachment oAttach = oMsg.Attachments.Add(sSource, iAttachType, iPosition, sDisplayName);

        // If you want to, display the message.
        // oMsg.Display(true);  //modal

        //Send the message.
        oMsg.Save();
        oMsg.Send();

        //Explicitly release objects.
        oTORecip = null;
        oCCRecip = null;
        oAttach = null;
        oMsg = null;
        oApp = null;
    }

Set MailItem.SendUsingAccount property on oMsg

http://msdn.microsoft.com/en-us/library/office/ff869311%28v=office.14%29.aspx

you can select only from Application.Session.Accounts collection.

or possibly check

MailItem.SentOnBehalfOfName http://msdn.microsoft.com/en-us/library/office/ff862145%28v=office.14%29.aspx

(for exchange)

There are some similar posts:

EDIT

Following code is ok with intellisense, check your DLL version. Checked with v 14 and v 12 of Outlook PIA.

Package downloaded from http://www.microsoft.com/en-us/download/details.aspx?id=43664

using Microsoft.Office.Interop.Outlook;
//C:\Program Files\Microsoft Visual Studio 11.0\Visual Studio Tools for Office\PIA\Office14\Microsoft.Office.Interop.Outlook.dll
//14.0.0.0 or 12.0.0.0 - it works from Outlook 2007 and higher

namespace ConsoleApplication1
{
    class Program
    {
        public void SendMail()
        {
            //// Create the Outlook application by using inline initialization.
            Application oApp = new Application();
            ////Create the new message by using the simplest approach.
            MailItem oMsg = (MailItem)oApp.CreateItem(OlItemType.olMailItem);
            oMsg.SendUsingAccount = oApp.Session.Accounts[2]; // it starts at 1

...

It seems you are using some other assembly DLL because for me the statement "using Microsoft.Office.Interop;" does not work at all.
