Computes the average of a sequence of nullable values.
public static System.Threading.Tasks.ValueTask<double?> AverageAsync(this System.Collections.Generic.IAsyncEnumerable<long?> source, System.Threading.CancellationToken cancellationToken = default);static member AverageAsync : System.Collections.Generic.IAsyncEnumerable<Nullable<int64>> * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<Nullable<double>><Extension()>
Public Function AverageAsync (source As IAsyncEnumerable(Of Nullable(Of Long)), Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of Nullable(Of Double))Parameters
- source
- IAsyncEnumerable<Nullable<Int64>>
A sequence of nullable values to calculate the average of.
- cancellationToken
- CancellationToken
The CancellationToken to monitor for cancellation requests. The default is None.
Returns
The average of the sequence of values, or null if the source sequence is empty or contains only values that are null.
Exceptions
source is null.
The sum of the elements in the sequence is larger than MaxValue (via the returned task).
source contains no elements (via the returned task).
