WhenEach(IEnumerable<Task>)
- Source:
- Task.cs
Creates anIAsyncEnumerable<T> that will yield the supplied tasks as those tasks complete.

- tasks
- IEnumerable<Task>
The tasks to iterate through as they complete.
Returns
AnIAsyncEnumerable<T> for iterating through the supplied tasks.
Applies to
WhenEach(ReadOnlySpan<Task>)
- Source:
- Task.cs
Creates anIAsyncEnumerable<T> that will yield the supplied tasks as those tasks complete.

- tasks
- ReadOnlySpan<Task>
The tasks to iterate through as they complete.
Returns
AnIAsyncEnumerable<T> for iterating through the supplied tasks.
Applies to
WhenEach(Task[])
- Source:
- Task.cs
Creates anIAsyncEnumerable<T> that will yield the supplied tasks as those tasks complete.
public: static System::Collections::Generic::IAsyncEnumerable<System::Threading::Tasks::Task ^> ^ WhenEach(... cli::array <System::Threading::Tasks::Task ^> ^ tasks);public static System.Collections.Generic.IAsyncEnumerable<System.Threading.Tasks.Task> WhenEach(params System.Threading.Tasks.Task[] tasks);static member WhenEach : System.Threading.Tasks.Task[] -> System.Collections.Generic.IAsyncEnumerable<System.Threading.Tasks.Task>Public Shared Function WhenEach (ParamArray tasks As Task()) As IAsyncEnumerable(Of Task)Parameters
- tasks
- Task[]
The task to iterate through when completed.
Returns
AnIAsyncEnumerable<T> for iterating through the supplied tasks.
Exceptions
tasks isnull.
tasks contains anull.
Remarks
The supplied tasks will become available to be output via the enumerable once they've completed. The exact order in which the tasks will become available is not defined.
