推荐答案

这里是另一种方法.使用此导出的函数创建一个C DLL:

Here is an alternate approach. Create a C DLL with this exported function:

extern "C" __declspec(dllexport) void MoveDirectory(
    const wchar_t* source, const wchar_t* destination)
{
    SHFILEOPSTRUCT fop = {};
    fop.wFunc = FO_MOVE;

    fop.pFrom = source;
    fop.pTo = destination;

    SHFileOperation (&fop);

}

然后P/从C#调用它:

And P/Invoke it from C#:

[DllImport("SomeLib.dll", CharSet = CharSet.Unicode,
    CallingConvention = CallingConvention.Cdecl)]
public static extern void MoveDirectory(string source, string destination);

static void Main()
{
    MoveDirectory("c:\\abc\0", "d:\\abc\0");
}

请注意，我在字符串中添加了额外的NULL.这是必需的，不是错字.

Notice the extra NULLs I added to the string. That is required and is not a typo.

您使用的是Directory.Move吗?如果是这样，尝试移动到其他驱动器时会遇到什么错误?

是的，这不适用于所有卷.您可以递归创建目录并复制文件，然后删除源目录.这项工作有些繁琐，但是Google进行了快速搜索，发现了一些现有的解决方案(人们已经编写了递归方法来做到这一点.).

Are you using Directory.Move? If so, what error do you get when you try to move to a different drive?

[Update]

Yes, that won''t work across volumes. You could recursively create directories and copy files over, and then delete the source directory. It''s a bit of work but a quick google search reveals a few existing solutions (people have written recursive methods to do this).
