Public Function Select(Of TSource, TResult) (source As IAsyncEnumerable(Of TSource), selector As Func(Of TSource, Integer, CancellationToken, ValueTask(Of TResult))) As IAsyncEnumerable(Of TResult)Type Parameters
- TSource
The type of the elements of source.
- TResult
The type of the value returned by selector.
Parameters
- source
- IAsyncEnumerable<TSource>
A sequence of values to invoke a transform function on.
- selector
- Func<TSource,Int32,CancellationToken,ValueTask<TResult>>
A transform function to apply to each element; the second parameter of the function represents the index of the source element.
Returns
An IAsyncEnumerable<T> whose elements are the result of invoking the transform function on each element of source.
Exceptions
selector is null.
