c# - LINQ 如何向这条语句添加一个 order by？

Question

我有以下 LINQ，我也想按文件创建日期排序，这是怎么做到的？

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

Answer 1

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

或

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