How can I get member variable class(int) from object Item in the below function? I can see it in Visual Studio debugger dynamic view. but not sure how could I access this programmatically.

        private void ThisAddIn_Startup(object sender, System.EventArgs e)
        {
            Application.ItemSend  = new Outlook.ApplicationEvents_11_ItemSendEventHandler(Application_ItemSend);

void Application_ItemSend(object Item, ref bool Cancel)

I want to use something like (int)Item.class So I can see Item's class such as mailitem, taskitem or meetingitem. and process accordingly.

You can use standard .net ways of checking the item type at runtime, for example:

            if (Item is Outlook.MailItem)
            {
                Outlook.MailItem mailItem =
                    (Item as Outlook.MailItem);
                itemMessage = "The item is an e-mail message."  
                    " The subject is "   mailItem.Subject   ".";
                mailItem.Display(false);
            }
            else if (Item is Outlook.ContactItem)
            {
                Outlook.ContactItem contactItem =
                    (Item as Outlook.ContactItem);
                itemMessage = "The item is a contact."  
                    " The full name is "   contactItem.Subject   ".";
                contactItem.Display(false);
            }
            else if (Item is Outlook.AppointmentItem)
            {
                Outlook.AppointmentItem apptItem =
                    (Item as Outlook.AppointmentItem);
                itemMessage = "The item is an appointment."  
                    " The subject is "   apptItem.Subject   ".";
            }
            else if (Item is Outlook.TaskItem)
            {
                Outlook.TaskItem taskItem =
                    (Item as Outlook.TaskItem);
                itemMessage = "The item is a task. The body is "
                      taskItem.Body   ".";
            }
            else if (Item is Outlook.MeetingItem)
            {
                Outlook.MeetingItem meetingItem =
                    (Item as Outlook.MeetingItem);
                itemMessage = "The item is a meeting item. "  
                     "The subject is "   meetingItem.Subject   ".";
            }

Either use the Class property (it is exposed by all OOM objects) - it will be 43 (OlObjectClass.olMail) for the MailItem objects, or use "is" and/or "as" operators.
