}
static void Main()
{
FillDataSet();
}

new SqlDataAdapter(queryString, connectionString))
{
// Add the handlers.
dataAdapter.SelectCommand.Connection.StateChange
+= new StateChangeEventHandler(OnStateChange);
// Create a DataSet.
DataSet dataSet = new DataSet();
// Fill the DataSet, which fires several StateChange events.
dataAdapter.Fill(dataSet, 0, 5, "Table");
}
}
protected static void PrintEventArgs(StateChangeEventArgs args)
{
Console.WriteLine("StateChangeEventArgs");
