Answer 1

You can try something like this

public static void CompactAndRepair(string accessFile, Microsoft.Office.Interop.Access.Application app)
        {
            string tempFile = Path.Combine(Path.GetDirectoryName(accessFile),
                              Path.GetRandomFileName() + Path.GetExtension(accessFile));

            app.CompactRepair(accessFile, tempFile, false);
            app.Visible = false;

            FileInfo temp = new FileInfo(tempFile);
            temp.CopyTo(accessFile, true);
            temp.Delete();
        }

objJRO.GetType().InvokeMember("CompactDatabase",
    System.Reflection.BindingFlags.InvokeMethod,
    null,
    objJRO,
    oParams);
