“移动不能跨卷工作"- 为什么?以及如何克服? [英] "Move will not work across volumes" - Why? And how to overcome?

问题描述

为什么当源文件和目标文件在不同的分区时 File.Move(sourceFileName, destFileName) 工作正常，但是 Directory.Move(sourceDirName, destDirName)代码> 不?它抛出

Why is it that File.Move(sourceFileName, destFileName) works fine when the source file and destination files are in different partitions, but Directory.Move(sourceDirName, destDirName) don't? It throws

System.IO.IOException: "源和目标路径必须有同根.移动不能跨卷工作."

System.IO.IOException: "Source and destination path must have identical roots. Move will not work across volumes."

我什至尝试创建一个 DirectoryInfo 实例并使用 MoveTo(destDirName) 方法，但没有成功.

I even tried to create a DirectoryInfo instance and use the MoveTo(destDirName) method but without success.

我错过了什么吗?我真的必须自己实现移动"功能吗?(顺便说一下，我要移动的目录很大).

Am I missing something? Do I really have to implement a "move" functionality myself? (the directory I want to move is very large btw).

推荐答案

您还可以 p/invoke SHFileOperation 与 Windows 资源管理器用来移动目录的功能相同.它将根据需要执行真正的移动或递归复制然后删除.

You can also p/invoke SHFileOperation which is the same function Windows Explorer uses to move directories around. It will either perform a true move or recursive-copy-then-delete, as appropriate.

它还可以显示与资源管理器相同的进度 UI，只需设置一个标志即可.

It can also show the same progress UI as explorer, just by setting a flag.
