经典多线程任务分发合并模型

最近写了个关于多线程的分发合并代码：

public static string GetCSVStringFromFacotry(int MaximumCurveNumber,IEmerable<IData> revertEligible)
    {
        int currenttotalNumverOfCurve = revertEligible.Count();
        List<Task> tasks = new List<Task>();
        int startIndex = 0;
        while (currenttotalNumverOfCurve > 0)
        {
            List<IData> currentExecuteCurveList = new List<IData>();
            for (int i = startIndex; i < startIndex + MaximumCurveNumber; i++)
            {
                if(revertEligible.Count() > i)
                    currentExecuteCurveList.Add(revertEligible.ElementAt(i));
            }

            tasks.Add(Task.Factory.StartNew
                (
                () =>
                {
                    string content = GetOneTimeCSVStringFromFacotry(currentExecuteCurveList);
                    //Remove header
                    lock (result)
                    {
                        if (!string.IsNullOrWhiteSpace(result))
                        {
                            //Remove header
                            content = RemoveCSVHeader(content);
                        }
                        result += content;
                    }
                }
            ));
            currenttotalNumverOfCurve -= MaximumCurveNumber;
            startIndex += MaximumCurveNumber;
        }
        try
        {
            Task.WaitAll(tasks.ToArray());
        }
        catch (AggregateException ae)
        {
            foreach (var innerException in ae.InnerExceptions)
            {
                log.Error("Exception in GetCSVStringFromFacotry", innerException);
            }
        }
        return result;
    }
