Question

I am developing a WPF 4.0 application in which we get the data from a remote web service. The web service exposes around 120+ methods to its clients. If a web service call from my WPF application fails, I need to retry it n times which is configurable via App.Config. How to implement this? Are there any design patterns that address this problem?

Answer 1

static T TryNTimes<T>(Func<T> func, int times)
{
  while (times>0)
  {
     try
     {
        return func();
     }
     catch(Exception e)
     {
       if (--times <= 0)
          throw;
     }

  }
}
