Directory.Delete()/.Create()是否同步? [英] Is Directory.Delete() / .Create() synchronous?

问题描述

using System.IO;
Directory.Delete("someFolder",true);
Directory.Create("someFolder");

在删除目录之后还是在删除目录时，将执行第三行吗?我是否必须将第一个命令放入任务"并等待其完成?

Will the third line be executed after the dir was deleted or while the directory is being deleted? Do I have to put the first command into a "Task" and wait until it is finished?

推荐答案

这是一个较旧的问题，但值得注意- Directory.Delete 最终会调用Windows的 RemoveDirectory 函数，哪个将标记为要删除的目录，但是在关闭所有文件句柄之前，文件系统不会实际上将其删除(

This is an older question but worth noting - Directory.Delete ultimately calls the RemoveDirectory Windows function, which marks the directory as to-be-deleted, but the filesystem won't actually delete it until all file handles are closed (see docs). As a result it is perfectly possible to return from Directory.Delete and find the directory still exists.
