C# LINQ如何将order by添加到此语句中？

我有下面的LINQ，我也想按文件创建日期订购，这是如何做到的

taskFiles = taskDirectory.GetFiles(Id + "*.xml")
 .Where(fi => !fi.Name.EndsWith("_update.xml", StringComparison.CurrentCultureIgnoreCase))
 .ToArray();

或

var taskFiles = from taskFile in taskDirectory.GetFiles(Id + "*.xml")
                where !taskFile.Name.EndsWith("_update.xml", StringComparison.CurrentCultureIgnoreCase)
                orderby taskFile.CreationTime
                select taskFile;

var taskFiles = from taskFile in taskDirectory.GetFiles(Id + "*.xml")
                where !taskFile.Name.EndsWith("_update.xml", StringComparison.CurrentCultureIgnoreCase)
                orderby taskFile.CreationTime
                select taskFile;
