IDataRecord::GetOrdinal Method (String^)
.NET Framework (current version)
Return the index of the named field.
Assembly: System.Data (in System.Data.dll)
Parameters
- name
-
Type:
System::String^
The name of the field to find.
GetOrdinal performs a case-sensitive lookup first. If it fails, a second case-insensitive search is made. GetOrdinal is kana-width insensitive. If the index of the named field is not found, an IndexOutOfRangeException is thrown.
Because ordinal-based lookups are more efficient than named lookups, it is inefficient to call GetOrdinal within a loop. Save time by calling GetOrdinal one time and assigning the results to an integer variable for use within the loop.
The following example demonstrates how to use the inherited GetOrdinal method.
