    fieldName : String
) : int

參數

• fieldName
  型別：System. . :: . .String
  The name of the field to find.

傳回值

型別：System. . :: . .Int32
The index of the named field.

備註

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

GetOrdinal is 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.
