That's just how <a href="http://msdn.microsoft.com/en-us/library/wz42302f.aspx" rel="nofollow">Directory.GetFiles</a> works. From the manual:

<blockquote>
 When using the asterisk wildcard character in a searchPattern, such as
 "*.txt", the matching behavior when the extension is exactly three
 characters long is different than when the extension is more or less
 than three characters long. A searchPattern with a file extension of
 exactly three characters returns files having an extension of three or
 more characters, where the first three characters match the file
 extension specified in the searchPattern.

From <a href="http://msdn.microsoft.com/en-us/library/ms143327.aspx" rel="nofollow">MSDN:</a>

<blockquote>
 When using the asterisk wildcard character in a searchPattern (for
 example, "*.txt"), the matching behavior varies depending on the
 length of the specified file extension. A searchPattern with a file
 extension of exactly three characters returns files with an extension
 of three or more characters, where the first three characters match
 the file extension specified in the searchPattern. A searchPattern
 with a file extension of one, two, or more than three characters
 returns only files with extensions of exactly that length that match
 the file extension specified in the searchPattern. When using the
 question mark wildcard character, this method returns only files that
 match the specified file extension. For example, given two files in a
 directory, "file1.txt" and "file1.txtother", a search pattern of
 "file?.txt" returns only the first file, while a search pattern of
 "file*.txt" returns both files.

<code>Directory.GetFiles</code> internally uses <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/aa364418%28v=vs.85%29.aspx" rel="nofollow"><code>FindFirstFile</code> function from Win32 API</a>. 

From the documentation of <code>FindFirstFile</code>:

<blockquote>
 • The search includes the long and short file names.
</blockquote>

A file that has long file name of <code>asd.tiff</code> will have a short file name like <code>asd~1.tif</code> and this is why it shows up in the results.

More than three character extensions are matched except when the path is on a network share (or mapped drive). For some reason the pattern only matches the long file name on remote drives.

So, I feel lame for asking this, but I'm kinda stumped. I'm trying to get a list of file in a directory that end in tif ... only tif ... not tiff. So, I did this in C# ...

<pre><code>Directory.GetFiles(path, "*.tif", SearchOption.TopDirectoryOnly);
</code></pre>

I would expect it to only return tif files, but that is not the case. I get tiff as well. I would think that if I supplied the mask .tif? that would get me both, but not the mask .tif. I tried it at a command prompt as well and I am getting both as well in DOS. Am I missing something here? This just seems wrong to me. I guess I could sanitize the results afterwards, but if I don't have to that would be best.

所以，我觉得问这个问题很差劲，但我有点困惑。我想在一个以tif结尾的目录中得到一个文件列表.只有蒂夫..。不是蒂夫。所以，我在C# .Directory.GetFiles(path, "*.tif", SearchOption.TopDirectoryOnly);我希望它只返回tif文件，但事实并非如此。我也会被骗的。...
