Folder management using IMAP (create, delete, rename)

Here’s the simple example that creates, renames and deletes an IMAP folder:

// C# version:

using Limilabs.Mail;
using Limilabs.Client.IMAP;

class Program
{
    static void Main(string[] args)
    {
       using (Imap imap = new Imap())
       {
           imap.Connect("server.company.com");
           imap.Login("user", "password");

           imap.SelectInbox();

           imap.CreateFolder("New folder");
           imap.RenameFolder("New folder", "Better name");
           imap.DeleteFolder("Better name");

           imap.Close();
       }
    }
};

' VB.NET version:

Imports Limilabs.Mail
Imports Limilabs.Client.IMAP

Public Module Module1
    Public Sub Main(ByVal args As String())

        Using imap As New Imap()
            imap.Connect("server.company.com")
            imap.Login("user", "password")

            imap.SelectInbox()

            imap.CreateFolder("New folder")
            imap.RenameFolder("New folder", "Better name")
            imap.DeleteFolder("Better name")

            imap.Close()
        End Using

    End Sub
End Module
