Cleanest way to write retry logic?

Question

Occasionally I have a need to retry an operation several times before giving up. My code is like:

int retries = 3;
while(true) {
  try {
    DoSomething();
         


        

Answer 1

You should try Polly. It's a .NET library written by me that allows developers to express transient exception handling policies such as Retry, Retry Forever, Wait and Retry or Circuit Breaker in a fluent manner.

Example

Policy
    .Handle(ex => ex.Number == 1205)
    .Or(ex => ex.ParamName == "example")
    .WaitAndRetry(3, retryAttempt => TimeSpan.FromSeconds(3))
    .Execute(() => DoSomething());
