如何有效重构此代码？

Question

我创建了一些使用EWS API的C＃代码。大部分是google-fu，因为我只用C＃编写了几周的东西。我的老板要求我重构代码以使其与某种样式匹配，但是我完全迷失了（因为我不知道自己在做什么！）

我尝试对代码进行多次更改，但始终面临着一片红色。 我使用了内置的重构，但是它正在创建新的方法，并且仍未编译。

static void Main(string[] args)
{
    try
    {
        FindItemsResults<Item> findResults;
        ConfigureExchangeSearchResults(out ExchangeService service, out SearchFilter sf, out ItemView view);

        if (Settings.Default.envLive == true)
        {
            findResults = ProcessLiveEmails(service, sf, view);
        }
        else
        {
            FindFoldersResults findFolderResults = service.FindFolders(WellKnownFolderName.Inbox, new FolderView(int.MaxValue));
            foreach (Folder folder in findFolderResults.Folders)
            {
                logger.Info(folder.DisplayName);
                if (folder.DisplayName == Settings.Default.envFolder)
                {
                    do
                    {
                        findResults = service.FindItems(folder.Id, sf, view);
                        logger.Info("Found " + findResults.TotalCount + " Messages");
                        foreach (Item item in findResults.Items)
                        {
                            logger.Info(item.DateTimeReceived);
                            EmailMessage message = EmailMessage.Bind(service, item.Id, new PropertySet(BasePropertySet.IdOnly, ItemSchema.Attachments, ItemSchema.HasAttachments, EmailMessageSchema.IsRead, ItemSchema.DateTimeReceived));
                            CheckMessageReceivedDate(message);
                            message.IsRead = true;
                                message.Update(ConflictResolutionMode.AutoResolve);
                        }
                    }
                    while (findResults.MoreAvailable);
                }
            }
        }
    }
    catch (Exception e)
    {
        logger.Error(e, "Error Occured On: " + DateTime.Now + " - Error Details: " + e.Message);
    }
    NLog.LogManager.Shutdown();
}

这是我当前的代码。我被要求将其重构为：

static void Main(string[] args)
{
    try
    {
        ExchangeService service;
        SearchFilter sf;
        ItemView view;
        ConfigureExchangeSearchParameters(out service, out sf, out view);

        if (settings.Default.envLive == true)
        {
            ProcessLiveEmails(service, sf, view);
        }
        else
        {
            ProcessTestEmails(service, sf, view);
        }
    }
    catch (Exception e)
    {
        logger.Error(e, "Error Occurred On: " + DateTime.Now + " - Error Details: " + e.Message);
    }
    NLog.LogManager.Shutdown();
}

本月晚些时候，我准备了一些C＃培训课程，但是我需要先整理一下这些课程！

任何帮助将不胜感激。

ETA： 这是ProcessLiveEmails和ProcessTestEmails的重构方法：

 private static FindItemsResults<Item> ProcessTestEmails(ExchangeService service, SearchFilter sf, ItemView view)
    {
        FindItemsResults<Item> findResults;
        FindFoldersResults findFolderResults = service.FindFolders(WellKnownFolderName.Inbox, new FolderView(int.MaxValue));
        foreach (Folder folder in findFolderResults.Folders)
        {
            logger.Info(folder.DisplayName);
            if (folder.DisplayName == Settings.Default.envFolder)
            {
                do
                {
                    findResults = service.FindItems(folder.Id, sf, view);
                    logger.Info("Found " + findResults.TotalCount + " Messages");
                    foreach (Item item in findResults.Items)
                    {
                        logger.Info(item.DateTimeReceived);
                        EmailMessage message = EmailMessage.Bind(service, item.Id, new PropertySet(BasePropertySet.IdOnly, ItemSchema.Attachments, ItemSchema.HasAttachments, EmailMessageSchema.IsRead, ItemSchema.DateTimeReceived));
                        CheckMessageReceivedDate(message);
                        message.IsRead = true;
                        message.Update(ConflictResolutionMode.AutoResolve);
                    }
                }
                while (findResults.MoreAvailable);
            }
        }

       return findResults;
    }

    private static void ConfigureExchangeSearchResults(out ExchangeService service, out SearchFilter sf, out ItemView view)
    {
        service = new ExchangeService(ExchangeVersion.Exchange2010_SP2)
        {
            UseDefaultCredentials = true
        };
        service.AutodiscoverUrl(Properties.Settings.Default.autoURL, RedirectionUrlValidationCallback);
        sf = new SearchFilter.SearchFilterCollection(LogicalOperator.And, new SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, false));
        view = new ItemView(int.MaxValue);
        view.OrderBy.Add(ItemSchema.DateTimeReceived, SortDirection.Ascending);
    }





    private static FindItemsResults<Item> ProcessLiveEmails(ExchangeService service, SearchFilter sf, ItemView view)
    {
        FindItemsResults<Item> findResults;
        do
        {
            findResults = service.FindItems(WellKnownFolderName.Inbox, sf, view);
            logger.Info("Found " + findResults.TotalCount + " Messages");
            foreach (Item item in findResults.Items)
            {
                logger.Info(item.DateTimeReceived);
                EmailMessage message = EmailMessage.Bind(service, item.Id, new PropertySet(BasePropertySet.IdOnly, ItemSchema.Attachments, ItemSchema.HasAttachments, EmailMessageSchema.IsRead, ItemSchema.DateTimeReceived));
                CheckMessageReceivedDate(message);
                message.IsRead = true;
                message.Update(ConflictResolutionMode.AutoResolve);
            }
        }
        while (findResults.MoreAvailable);
        return findResults;
    }

ProcessLiveEmails似乎很好，问题出在ProcessTestEmails，特别是最后一行：

return findResults;
