public class NoRetryPolicy : IRetryPolicy

Methods

ExecuteAsync<T>(IRetryPolicy.RetriedOperation<T>, IRetryPolicy.ShouldRetryChecker<T>, CancellationToken, IProgress<RetryQueuedProgress>)

An async method that can retry an operation if it hasn't succeeded.

Declaration

public async Task<T> ExecuteAsync<T>(IRetryPolicy.RetriedOperation<T> retriedOperation, IRetryPolicy.ShouldRetryChecker<T> shouldRetryChecker, CancellationToken cancellationToken = default(CancellationToken), IProgress<RetryQueuedProgress> progress = null)

Parameters

Type	Name	Description
IRetryPolicy.RetriedOperation<T>	retriedOperation	The IRetryPolicy.RetriedOperation<T> that needs to be performed.
IRetryPolicy.ShouldRetryChecker<T>	shouldRetryChecker	A IRetryPolicy.ShouldRetryChecker<T> that helps determine whether the retriedOperation should be retried.
CancellationToken	cancellationToken	Token to cancel the task execution.
IProgress<RetryQueuedProgress>	progress	Provider for progress updates on queued retries.

Returns

Type	Description
Task<T>	The result of the retriedOperation, if available, after shouldRetryChecker returns false.

Type Parameters

Name	Description
T

Implements

IRetryPolicy.ExecuteAsync<T>(IRetryPolicy.RetriedOperation<T>, IRetryPolicy.ShouldRetryChecker<T>, CancellationToken, IProgress<RetryQueuedProgress>)

Exceptions

Type	Condition
RetryExecutionFailedException	When shouldRetryChecker returns false after retriedOperation throws an exception, in which case the internal exception is passed through the former's innerException field. When shouldRetryChecker throws an RetryExecutionFailedException, in which case this exception is immediately bubbled up.
TimeoutException	When the retry policy expires.
OperationCanceledException	When the retriedOperation or the cancellationToken is cancelled.
InvalidArgumentException	When shouldRetryChecker throws an invalid exception. When shouldRetryChecker does not await the completion of operationTask.
