ParallelHelperForAsyncT(T, Int32, Int32, TaskConfig, ActionInt32) Method

public static Task<bool> ForAsync<T>(
	T operation,
	int fromInclusive,

	Action<int> body
)

Public Shared Function ForAsync(Of T) ( 
	operation As T,
	fromInclusive As Integer,
	toExclusive As Integer,
	asyncConfig As TaskConfig,
	body As Action(Of Integer)
) As Task(Of Boolean)

static Task<bool>^ ForAsync(
	T operation, 
	int fromInclusive, 
	int toExclusive, 
	TaskConfig^ asyncConfig, 
	Action<int>^ body
)

static member ForAsync : 
        operation : 'T * 
        fromInclusive : int * 
        toExclusive : int * 
        asyncConfig : TaskConfig * 
        body : Action<int> -> Task<bool> 

Parameters

operation  T

The operation to be reported when Progress is set in asyncConfig. Progress is reported only if this parameter is not .

fromInclusive  Int32

The start index, inclusive.

toExclusive  Int32

The end index, exclusive.

asyncConfig  TaskConfig

An optional configuration to adjust parallelization, cancellation, completion callback or reporting progress.

body  ActionInt32

The delegate that is invoked once per iteration.

Type Parameters

T

The type of the operation parameter.

Return Value

If fromInclusive is greater than or equal to toExclusive, then the operation completes synchronously without performing any iterations.

If operation is not , Progress is set in asyncConfig and there is at least one iteration, then the IAsyncProgress.New method will be called before the first iteration passing the specified operation to the operationType parameter. It will be followed by as many IAsyncProgress.Increment calls as many iterations were completed successfully.

This method is not a blocking call even if the MaxDegreeOfParallelism property of the asyncConfig parameter is 1.
