public Subindex<T,TKey> Add<TKey>( Expression<Func<T,TKey>> keySelector, bool keyIsUnique, bool onlyOnce, CultureInfo locale )
Parameters
- keySelector
- Key selector expression of the subindex, see KeySelector.
- keyIsUnique
- Specifies whether the key used in this subindex is unique for any given value of the parent key (default: false).
- onlyOnce
- Specifies whether it is required that the subindex does not exist prior to this method call (default: false). If a subindex with this keySelector already exists, an exception is thrown if it is true, and this method call is ignored if it is false.
- locale
- Locale information used to compare strings in the subindex (default: CultureInfo.CurrentCulture).
Type Parameters
- TKey
- The type of the subindex key.
Return Value
The new subindex added to its parent's IndexDefinition<T>.Subindexes collection.
