DirectoryInfo.GetFiles已损坏 [英] DirectoryInfo.GetFiles is broken

问题描述

MSDN> 当扩展名完全是

三个字符长时，searchPattern的匹配行为与扩展名超过

三个字符长时不同。正好三个字符的searchPattern返回

文件，其扩展名为三个或更多字符。一个，两个或三个以上字符的一个，两个或三个以上字符的searchPattern只返回具有完全长度的扩展名

的文件。


什么< BLEEP>他们的想法是什么！


好​​吧，不是说我的系统没有...


由于可能的原因，MS决定了" * ABC"。应解释为

" * .abc *"？

three characters long. A searchPattern of exactly three characters returns
files having an extension of three or more characters. A searchPattern of
one, two, or more than three characters returns only files having extensions

WHAT THE <BLEEP> WERE THEY THINKING!

Ok, not that I have that out of my system...

For what possible reason did MS decide that "*.abc" should be interpreted as
"*.abc*"?

为什么可能的原因做了MS决定* .abc应该将
解释为*。abc *？


因为当你说*。abc时，它不知道你是指文件的长名称还是它的b / b
的简称。文件名1234567890.abcdef

的简称123456~1.abc符合你的模式。

Because when you say "*.abc", it doesn''t know if you are referring to
the file''s longname or it''s shortname. A file name "1234567890.abcdef" has
a short name of "123456~1.abc" which matches your pattern.

不确定您运行的是哪个OS .NET版本，但它在带有.NET v1.1 SP1的

XP SP2上按预期工作。


如果一个目录包含：

readme.abc

和

readme.abcde


GetfFiles（*。abc"）

只返回readme.abc

Not sure what OS .NET version you are running, but it works as expected on
XP SP2 with .NET v1.1 SP1.

so if a directory contains:
readme.abc
and
readme.abcde

GetfFiles(*.abc")
only returns readme.abc

我的带有.NET v1.1 w / o SP1的XP SP2就像文档所述的那样工作。


GetfFiles（" *。abc" ）发现：


c：\readme.abc

c：\readme.abcde


只是什么<寻呼>他们在想什么？ ：^）


安装SP1后我会再试一次，看看会发生什么......

My XP SP2 with .NET v1.1 w/o SP1 works just as the documentation states.

GetfFiles("*.abc") finds:

c:\readme.abc
c:\readme.abcde

JUST WHAT THE <BLEEP> WERE THEY THINKING? :^)

I''ll try it again after installing SP1 and see what happens...
