通用尝试并在C#中使用超时重试？

public async Task<T> RetryOnTimeoutAsync<T>(Func<Task<T>> func, int maxRetryCount, TimeSpan timeout)
{
    int retryCount = 0;
    while (true)
    {
        try
        {
            using (var timeoutCancellationTokenSource = new CancellationTokenSource())
            {
                var task = func();
                await Task.WhenAny(task, Task.Delay(timeout, timeoutCancellationTokenSource.Token));
                timeoutCancellationTokenSource.Cancel();
                return await task;
            }
        }
        catch (OperationCanceledException)
        {
            retryCount++;
            if (retryCount >= maxRetryCount)
            {
                throw;
            }
        }
    }
}
