Public Shared Function ForAsync(Of T As IBinaryInteger(Of T)) (fromInclusive As T, toExclusive As T, parallelOptions As ParallelOptions, body As Func(Of T, CancellationToken, ValueTask)) As Task

Type Parameters

T

Parameters

fromInclusive
T

The start index, inclusive.

toExclusive
T

The end index, exclusive.

parallelOptions
ParallelOptions

An object that configures the behavior of this operation.

body
Func<T,CancellationToken,ValueTask>

An asynchronous delegate that is invoked once per element in the data source.

Returns

A task that represents the entire for each operation.

Exceptions

The body argument is null.

Remarks

The operation will execute at most ProcessorCount operations in parallel.

Type Parameters

T

Parameters

fromInclusive
T

The start index, inclusive.

toExclusive
T

The end index, exclusive.

cancellationToken
CancellationToken

body
Func<T,CancellationToken,ValueTask>

An asynchronous delegate that is invoked once per element in the data source.

Returns

A task that represents the entire for each operation.

Exceptions

The body argument is null.

The cancellation token was canceled. This exception is stored into the returned task.
