- TResult
The type of the elements of the sequence returned by selector.
Parameters
- source
- IAsyncEnumerable<TSource>
A sequence of values to project.
- selector
- Func<TSource,IAsyncEnumerable<TResult>>
A transform function to apply to each element.
Returns
An IAsyncEnumerable<T> whose elements are the result of invoking the one-to-many transform function on each element of the input sequence.
Exceptions
selector is null.
Applies to
SelectMany<TSource,TResult>(IAsyncEnumerable<TSource>, Func<TSource,CancellationToken,ValueTask<IEnumerable<TResult>>>)
- Source:
- SelectMany.cs
Projects each element of a sequence to an IEnumerable<T> and flattens the resulting sequences into one IAsyncEnumerable<T> sequence.
