] { get; }

This overload for Item behaves identically to the GetValue method.

The following example displays the contents of all the columns, in all the rows from the supplied DataTableReader. The code uses the Item method (the indexer, in Microsoft C#) to retrieve the value that is contained in each column.

private static void DisplayItems(DataTableReader reader)
{
    int rowNumber = 0;
    while (reader.Read())
    {
        Console.WriteLine("Row " + rowNumber);
        for (int i = 0; i < reader.FieldCount; i++)
        {
            Console.WriteLine("{0}: {1}", reader.GetName(i), reader[i]);
        }
        rowNumber++;
    }
}
