How to write retry logic in C#?
Retry logic is implemented whenever there is a failing operation. Implement retry logic only where the full context of a failing operation.
It's important to log all connectivity failures that cause a retry so that underlying problems with the application, services, or resources can be identified.
Example
class Program{ public static void Main(){ HttpClient client = new HttpClient(); dynamic res = null; var retryAttempts = 3; var delay = TimeSpan.FromSeconds(2); RetryHelper.Retry(retryAttempts, delay, () =>{ res = client.GetAsync("https://example22.com/api/cycles/1"); }); Console.ReadLine(); } } public static class RetryHelper{ public static void Retry(int times, TimeSpan delay, Action operation){ var attempts = 0; do{ try{ attempts++; System.Console.WriteLine(attempts); operation(); break; } catch (Exception ex){ if (attempts == times) throw; Task.Delay(delay).Wait(); } } while (true); } }
