Reading Outlook 2010 Folders - Is there a better way to do this?

Hello Everyone:

My goals are:

1. Use C# to find ALL mail folders in users Outlook ap


2. Read and display ALL emails in the C# Application

I'm working on goal one right now. Following is my script:

        private void All_Mail_Btn_Click(object sender, EventArgs e)
        {
            OutLook.Application app = new OutLook.Application();
            OutLook.NameSpace ns = app.GetNamespace("MAPI");

            foreach (Folder folder in ns.Folders)
            {
                GetFolders(folder);
            }
        }

And

        public void GetFolders(MAPIFolder folder)
        {
            string mailFldr = folder.Name.ToString();
            if (mailFldr == "Inbox" || mailFldr.StartsWith("Sent"))
            {
                Console.WriteLine("mail Folder Name: " + folder.Name + " ... Count: " + folder.Items.Count);
            }
            if (folder.Folders.Count > 0)
            {
                foreach (MAPIFolder subFolder in folder.Folders)
                {
                    GetFolders(subFolder);
                }

            }
         
        }

So... is this the most efficient way to read ONLY mail folders (and ALL inbox/sent folders)?

I'm asking - because it seems sort of convoluted to me to run GetFolders(subFolder) inside GetFolders(MAPIFolder folder)?

From experimentation, I can tell that the first round processes the root folders and the foreach (MAPIFolder subFolder in folder.Folders) processes subfolders. So ... in a way it makes sense.

But honestly - Accessing Outlook folders has to be a common need within Visual Studio, C# and VB ... is there no other way to do this??

In addition I understand MAPI is being depreciated ... so that is another reason I'm wondering if there is a more efficient way?

Any feedback would be appreciated.

Thanks in advance - Pavilion
