Retry

After setting WorkOption.RetryOption, if a work throws an exception and fails to execute, it will be retried according to the settings.
You can configure the retry behavior (immediate retry or requeue), set the number of retries, or allow for unlimited retries (properties to stop retrying are provided in both callback and WorkEnded event parameters).

powerPool.QueueWorkItem(() =>
{
    throw new Exception();
}, new WorkOption<object>()
{
    RetryOption = new RetryOption()
    {
        RetryBehavior = RetryBehavior.Requeue,
        RetryPolicy = RetryPolicy.Limited,
        MaxRetryCount = 5,
    },
    Callback = (res) =>
    {
        if (res.Status == Status.Failed)
        {
            if (res.RetryInfo.CurrentRetryCount == 2)
            {
                res.RetryInfo.StopRetry = true;
            }
        }
    }
});
