示例1: OnRowUpdating

// handler for RowUpdating event

   {
       PrintEventArgs(e);
   }

   //Handler for RowUpdated event.
   private static void OnRowUpdated(object sender, SqlRowUpdatedEventArgs e) 
   {
       PrintEventArgs(e);
   }

   public static int Main() 
   {
       const string CONNECTION_STRING = "Persist Security Info=False;Integrated Security=SSPI;database=northwind;server=mySQLServer";
       const string SELECT_ALL = "select * from Products";

       //Create DataAdapter.
       SqlDataAdapter rAdapter    = new SqlDataAdapter(SELECT_ALL, CONNECTION_STRING);
