GetOrdinal method


Description 

The column ordinal, given the column name.

Syntax 

int GetOrdinal( string name )

Parameters 

name    The column name.

Return Value 

The zero-based column ordinal.

Implements 

IDataRecord.GetOrdinal

Usage 

GetOrdinal performs a case-sensitive lookup first. If it fails, a second case-insensitive search is made.

GetOrdinal is Japanese kana-width insensitive.

Because ordinal-based lookups are more efficient than named lookups, it is inefficient to call GetOrdinal within a loop. Save time by calling GetOrdinal once and assigning the results to an integer variable for use within the loop.
