当调用 DirectoryInfo.GetDirectories（。）上它指向一个有效的文件夹（不包括驱动器根）一个DirectoryInfo类的实例，结果是一个DirectoryInfo的数组，其第一个（也是唯一一个）元素指向一个无效的目录名称相同的本身，本身下方。

When calling DirectoryInfo.GetDirectories(".") on an instance of a DirectoryInfo class which points to a valid folder (excluding drive roots), the result is a DirectoryInfo array whose first (and only) element points to a invalid directory named the same as itself, below itself.

例如：

static void Main(string[] args)
{
    DirectoryInfo di = new DirectoryInfo("c:temp");
    DirectoryInfo[] dis = di.GetDirectories(".");
    Console.WriteLine(dis[0].FullName);
}

打印出一个不存在的目录：

Prints out a non-existent directory:

c:temptemp

据我所知，在Windows中，一个。指当前目录。这或许可以被接受我，如果该方法返回C： TEMP，但返回假的子目录具有相同的名称似乎是绝对错误的行为。

I understand that in Windows, a "." refers to the current directory. That might be acceptable to me if the method returned "c:temp", but returning a fake subdirectory with the same name seems like absolutely the wrong behavior.

我应该可以断言，任何DirectoryInfo对象返回这个函数确实存在....吧？！

我反编译使用.net反射的类，但它导致了这种方法

I decompiled the class using .NET Reflector, but it leads to this method

internal static string[] InternalGetFileDirectoryNames(string path, string userPathOriginal, string searchPattern, bool includeFiles, bool includeDirs, SearchOption searchOption)"

这是一个野兽，我不喜欢通过逻辑在我的头上走。这显然​​是一个错误恕我直言。

Which is a BEAST and I don't feel like walking through the logic in my head. It's clearly a bug IMHO.

仅供参考 - 一个*为预期的工作，有人问前

FYI - a "*" works as expected, before someone asks.

推荐答案

我可以证实你说的话，并不能看到任何合理的解释吧，所以我投票的错误。

I can confirm what you say, and can't see any rational explanation for it, so I'm voting BUG.

我觉得这样很好，我其提交来微软

I think so as well, I submitted it to Microsoft
