Repeating a function in C# until it no longer throws an exception

Question

I\'ve got a class that calls a SOAP interface, and gets an array of data back. However, if this request times out, it throws an exception. This is good. However, I want m

Answer 1

I follow this pattern in order to solve this problem:

    public void Send(String data, Int32 attemptNumber)
    {
        try
        {
            yourCodeHere(data);
        }
        catch (WebException ex)
        {
            if (attemptNumber > 0)
                Send(data, --attemptNumber);
            else
                throw new AttemptNumberExceededException("Attempt number exceeded!", ex);
        }
        catch (Exception ex)
        {
            //Log pourpose code goes here!
            throw;
        }
    }

Trying forever seems not to be a good idea as you may end up having an infinite process. If you think you need many attempts to achieve your goal just set huge number here.

I personally think its wise to wait some milliseconds, or seconds after eac attempt Thread.Sleep(1000); before callig Send(data); --- you could for example, use the attempNumber variable to increse or decrease this waiting time if you think its wise for your scenario.
