Returns the column ordinal, given the column name.
Visual Basic
Public Overrides Function GetOrdinal( _
ByVal name As String _
) As Integer
C#
public override int GetOrdinal(
string name
);
name The column name.
The zero-based column ordinal.
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. You can save time by calling GetOrdinal once and assigning the results to an integer variable for use within the loop.
