I think you want to get parent folder name from file path. It is easy to get. 
One way is to create a <code>FileInfo</code> type object and use its <code>Directory</code> property.

Example:

<pre><code>FileInfo fInfo = new FileInfo("c:\projects\roott\wsdlproj\devlop\beta2\text\abc.txt");

String dirName = fInfo.Directory.Name;
</code></pre>

Simply use <code>Path.GetFileName</code>

Here - Extract folder name from the full path of a folder:

<pre><code>string folderName = Path.GetFileName(@"c:\projects\root\wsdlproj\devlop\beta2\text");//Return "text"
</code></pre>

Here is some extra - Extract folder name from the full path of a file:

<pre><code>string folderName = Path.GetFileName(Path.GetDirectoryName(@"c:\projects\root\wsdlproj\devlop\beta2\text\GTA.exe"));//Return "text"
</code></pre>

blocks|key|760869|text|我想除了进入文件系统来找出text.txt是一个目录还是仅仅是一个文件之外，没有别的办法。如果你想要一些简单的东西，也许你可以直接使用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|760870|s.Substring(s.LastIndexOf(@"\"));|code-block|syntax|javascript|760871|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

I figured there's no way except going into the file system to find out if text.txt is a directory or just a file. If you wanted something simple, maybe you can just use:

<pre><code>s.Substring(s.LastIndexOf(@"\"));
</code></pre>

blocks|key|976376|text|在这种情况下，您想要获取的文件存储在strpath变量中：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|976377|string+strPath+=+Server.MapPath(Request.ApplicationPath)+%2B+"/contents/member/"+%2B+strFileName;|code-block|syntax|javascript|976378|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

In this case the file which you want to get is stored in the strpath variable:

<pre><code>string strPath = Server.MapPath(Request.ApplicationPath) + "/contents/member/" + strFileName;
</code></pre>

blocks|key|976500|text|下面是另一种方法，它不需要创建DirectoryInfo对象就能为我工作。关键的一点是，当路径中没有尾部斜杠时，GetFileName()可以工作。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|976501|var+name+=+Path.GetFileName(path.TrimEnd(Path.DirectorySeparatorChar));|code-block|syntax|javascript|976502|示例：|976503|var+list+=+Directory.EnumerateDirectories(path,+"*")

Here is an alternative method that worked for me without having to create a DirectoryInfo object. The key point is that <code>GetFileName()</code> works when there is no trailing slash in the path.

<pre><code>var name = Path.GetFileName(path.TrimEnd(Path.DirectorySeparatorChar));
</code></pre>

Example:

<pre><code>var list = Directory.EnumerateDirectories(path, "*")
 .Select(p =&gt; new
 {
 id = "id_" + p.GetHashCode().ToString("x"),
 text = Path.GetFileName(p.TrimEnd(Path.DirectorySeparatorChar)),
 icon = "fa fa-folder",
 children = true
 })
 .Distinct()
 .OrderBy(p =&gt; p.text);
</code></pre>

blocks|key|760819|text|这也可以像这样做；|type|unstyled|depth|inlineStyleRanges|entityRanges|data|760820|var+directoryName+=+System.IO.Path.GetFileName(@"c:\projects\roott\wsdlproj\devlop\beta2\text");|code-block|syntax|javascript|760821|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]
