| SharedPtr<IEnumerable<ResultType> > System::Collections::Generic::IEnumerable< T >::LINQ_SelectMany | ( | const Func< T, SharedPtr< IEnumerable< ResultType >>> & | selector | ) |
Projects each element of a sequence and combines the resulting sequences into one sequence.
- Template Parameters
-
ResultType The type of the value returned by the selector.
- Parameters
-
selector A transform function.
- Returns
- An IEnumerable that contains the result of invoking a one-to-many projection function on each element of the input sequence.
◆ LINQ_SelectMany() [2/2]
| SharedPtr<IEnumerable<Result> > System::Collections::Generic::IEnumerable< T >::LINQ_SelectMany | ( | const Func< Source, SharedPtr< IEnumerable< Result >>> & | selector | ) |
