How to parse mails in Microsoft Outlook using C#?

We often get hundreds of mails in our Outlook Inbox and want to do some processing with these mails. This scenario arises mainly with the customer support people who wanted to act depending on the mail subject line. Here is a simple code to parse the Microsoft Outlook Inbox:

  static void ReadMail()
  {
            Microsoft.Office.Interop.Outlook.Application app = null;
            Microsoft.Office.Interop.Outlook._NameSpace ns = null;
            Microsoft.Office.Interop.Outlook.MailItem item = null;
            Microsoft.Office.Interop.Outlook.MAPIFolder inboxFolder = null;

            try
            {
                app = new Microsoft.Office.Interop.Outlook.Application();
                ns = app.GetNamespace("MAPI");
                ns.Logon(null, null, false, false);

                inboxFolder = ns.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderInbox);
                // subFolder = inboxFolder.Folders["Inbox"]; //folder.Folders[1]; also works
                Console.WriteLine("Folder Name: {0}, EntryId: {1}", inboxFolder.Name, inboxFolder.EntryID);
                Console.WriteLine("Num Items: {0}", inboxFolder.Items.Count.ToString());

                System.IO.StreamWriter strm = new System.IO.StreamWriter(@"d:\Test\Inbox.txt");
                for (int counter = 1; counter <= inboxFolder.Items.Count; counter++)
                {
                    item = (Microsoft.Office.Interop.Outlook.MailItem)inboxFolder.Items[counter];
                    Console.WriteLine("Item: {0}", counter.ToString());
                    Console.WriteLine("Subject: {0}", item.Subject);
                    Console.WriteLine("Sent: {0} {1}", item.SentOn.ToLongDateString(), item.SentOn.ToLongTimeString());
                    Console.WriteLine("Sendername: {0}", item.SenderName);
                    strm.WriteLine(counter.ToString() + "," + item.Subject + "," + item.SentOn.ToShortDateString() + "," + item.SenderName);
                }
                strm.Close();
            }
            catch (System.Runtime.InteropServices.COMException comException)
            {
                Console.WriteLine(comException.ToString());
            }
            finally
            {
                ns = null;
                app = null;
                inboxFolder = null;
            }

  }

Hope this helps you :)
