示例1: OnRowUpdating
// handler for RowUpdating event
private static void OnRowUpdating(object sender, SqlRowUpdatingEventArgs e)
{
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";

//Create DataAdapter.
SqlDataAdapter rAdapter = new SqlDataAdapter(SELECT_ALL, CONNECTION_STRING);
//Create and fill DataSet (Select only first 5 rows.).
DataSet rDataSet = new DataSet();
