using (OleDbConnection connection = new
OleDbConnection(ConfigurationManager.ConnectionStrings["Access"].ConnectionString))
{
  using (OleDbCommand command = new OleDbCommand(strSQL, connection))
  {
       command.CommandType = CommandType.Text;
       command.Parameters.Add(new OleDbParameter("@AlbumID", albumid));
       command.Parameters.Add(new OleDbParameter("@Size", (int)size));
      ...
   }
}

What is diference? Any performance improvement? I found the code above on a
starter kit

OleDbConnection connection = new
OleDbConnection(ConfigurationManager.ConnectionStrings["Access"].ConnectionString)
OleDbCommand command = new OleDbCommand(strSQL, connection)
command.CommandType = CommandType.Text;
command.Parameters.Add(new OleDbParameter("@AlbumID", albumid));
command.Parameters.Add(new OleDbParameter("@Size", (int)size));
...
