This tutorial illustrates how to obtain Mailbox information with a few lines of code in Ultimate IMAP Component. Other examples for SMTP and POP3 can also be found at SMTP blog and POP3 blog. The simplest way to obtain information about a specified mailbox is using the GetMailboxInfo method. You only need to pass the mailbox name to the method. It returns a Mailbox object containing information about the mailbox you have requested.

If you want to obtain mailbox information of a Gmail IMAP account, please ensure the imap client connection is enabled on the GMAIL account setting page as shown in this picture:

The following steps illustrate how to obtain mailbox information with Ultimate mail library:

1. Add using directives to your code to create aliases for existing ComponentSoft namespaces and avoid having to type the fully qualified type names. The code looks similar to the following:

   
   C#

   using ComponentSoft.Net;
   using ComponentSoft.Net.Mail;

   VB.NET

   Imports ComponentSoft.Net
   Imports ComponentSoft.Net.Mail

2. Create a new instance of the ImapClient class and call the Connect methods. The code looks similar to the following:
   C#

   // Create a new instance of the ImapClient class.
   ImapClient client = new ImapClient();
   // Connect to the server.
   client.Connect("myserver");
   // Or you can specify the IMAP port with
   // client.Connect("myserver", 143);
   // Login to the server.
   client.Authenticate("user", "password");
   // Get information about the INBOX mailbox.
   Mailbox m = client.GetMailboxInfo("INBOX");
   Console.WriteLine("The number of recent messages: " + m.RecentMessages);
   Console.WriteLine("The number of new unseen messages messages: " + m.NewUnseenMessages);
   // Close the connection.
   client.Disconnect();

   VB.NET

   ' Create a new instance of the ImapClient class.
   Dim client As New ImapClient()
   ' Connect to the server.
   client.Connect("myserver")
   ' Or you can specify the IMAP port with
   ' client.Connect("myserver", 143);
   ' Login to the server.
   client.Authenticate("user", "password")
   ' Get information about the INBOX mailbox.
   Dim m As Mailbox = client.GetMailboxInfo("INBOX")
   Console.WriteLine("The number of recent messages: " & m.RecentMessages)
   Console.WriteLine("The number of new unseen messages messages: " & m.NewUnseenMessages)
   ' Close the connection.
   client.Disconnect()
   

Now you have successfully connected to the IMAP server and obtained information about the mailbox on the server. This is just a basic steps to manipulate mailboxes and messages. For more advanced tutorials, you can download the Ultimate Mail Library and take a look at the documentation as well as a number of carefully designed sample projects.
