    Some code that may help you to achieve your goal.

    public static class Retry
{
   public static void Do(
       Action action,
       TimeSpan retryInterval,
       int retryCount = 3)
   {
       Do(() => 
       {
           action();
           return null;
       }, retryInterval, retryCount);
   }

   public static T Do(
       Func action, 
       TimeSpan retryInterval,
       int retryCount = 3)
   {
       var exceptions = new List();

       for (int retry = 0; retry < retryCount; retry++)
       {
          try
          { 
              if (retry > 0)
                  Thread.Sleep(retryInterval);
              return action();
          }
          catch (Exception ex)
          { 
              exceptions.Add(ex);
          }
       }

       throw new AggregateException(exceptions);
   }
}



    Call and retry as below:
    


    int result = Retry.Do(SomeFunctionWhichReturnsInt, TimeSpan.FromSeconds(1), 4);
