C# to move mail to PST

Question

I want to use C# to access my Outlook Sent Folder and move the messages there to a folder in my PST called Archive. This is the code I was working with, but I am getting multiple compile errors. Does someone here with more coding experience know how to accomplish this?

static void MoveMe()
{
try
{
    _app = new Microsoft.Office.Interop.Outlook.Application();
    _ns = _app.GetNamespace("MAPI");
    _ns.Logon(null, null, false, false);
    Application.ActiveExplorer().Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderOutbox);
    Outlook.Items SentMailItems = SentMail.Items;
    Outlook.MailItem newEmail = null;
    foreach (object collectionItem in SentMailItems)
    {
        moveMail.Move(Archive);
    }
}
catch (System.Runtime.InteropServices.COMException ex)
{
    Console.WriteLine(ex.ToString());
}
finally
{
    _ns = null;
    _app = null;
    _inboxFolder = null;
}
}

Error list from the comments:

1. Only assignment, call, increment, decrement, and new object expressions can be used as a statement
2. The type or namespace name 'Emails' could not be found (are you missing a using directive or an assembly reference?)
3. The name 'A_Sent' does not exist in the current context
4. The name 'moveMail' does not exist in the current context
5. The name 'SentMail' does not exist in the current context

here is an example of how you would get the source folder (SentItems) and move them to a PST(Archive).

using Outlook = Microsoft.Office.Interop.Outlook; 

public void MoveMyEmails()
    {
        //set up variables
        Outlook.Application oApp = null;
        Outlook.MAPIFolder oSource = null;
        Outlook.MAPIFolder oTarget = null;
        try
        {
            //instantiate variables
            oApp = new Outlook.Application();
            oSource = oApp.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderSentMail);
            oTarget = oApp.Session.Folders["Archive"];
            //loop through the folders items
            for (int i = oSource.Items.Count; i > 0; i--)
            {
                move the item
                oSource.Items[i].Move(oTarget);
            }
        }
        catch (Exception e)
        {
            //handle exception
        }
        //release objects
        if (oTarget != null)
        {
            System.Runtime.InteropServices.Marshal.ReleaseComObject(oTarget);
            GC.WaitForPendingFinalizers();
            GC.Collect();
        }
        if (oSource != null)
        {
            System.Runtime.InteropServices.Marshal.ReleaseComObject(oSource);
            GC.WaitForPendingFinalizers();
            GC.Collect();
        }
        if (oApp != null)
        {
            System.Runtime.InteropServices.Marshal.ReleaseComObject(oApp);
            GC.WaitForPendingFinalizers();
            GC.Collect();
        }

    }
