Namespace:  System.Data
Assembly:  System.Data (in System.Data.dll)

public override Object this[
	int ordinal
] { get; }

Parameters

ordinal
Type: System.Int32

The zero-based column ordinal.

Property Value

Type: System.Object
The value of the specified column in its native format.

Implements

IDataRecord.Item

ExceptionCondition
IndexOutOfRangeException

The index passed was outside the range of 0 to FieldCount - 1.

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++;
    }
}
