public:
virtual String^ GetName(
	int ordinal
) override

Parameters

ordinal
Type: System::Int32

The zero-based column ordinal

Return Value

Type: System::String^

The name of the specified column.

Implements

IDataRecord::GetName(Int32)

Exception Condition
ArgumentOutOfRangeException

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

InvalidOperationException

An attempt was made to read or access a column in a closed DataTableReader.

The GetName and GetOrdinal methods provide inverse functionality. That is, calling GetOrdinal on the return value of calling GetName should return the original parameter passed to GetName; the same applies to calling the procedures in the opposite order.

The following simple example includes a procedure that lists the names of all the columns within the specified DataTableReader, and the column's ordinal position, to the Console window.
