Get folder name from full file path

How do I get the folder name from the full path of the application?

This is the file path below,

c:\projects\root\wsdlproj\devlop\beta2\text

Here "text" is the folder name.

How can I get that folder name from this path?

See DirectoryInfo.Name:

string dirName = new DirectoryInfo(@"c:\projects\roott\wsdlproj\devlop\beta2\text").Name;

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

Example:

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

String dirName = fInfo.Directory.Name;

Try this

var myFolderName = @"c:\projects\roott\wsdlproj\devlop\beta2\text";
var result = Path.GetFileName(myFolderName);

You could use this:

string path = @"c:\projects\roott\wsdlproj\devlop\beta2\text";
string lastDirectory = path.Split(new char[] { System.IO.Path.DirectorySeparatorChar }, StringSplitOptions.RemoveEmptyEntries).Last();

Simply use Path.GetFileName

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

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

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

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

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:

s.Substring(s.LastIndexOf(@"\"));

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

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

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

var name = Path.GetFileName(path.TrimEnd(Path.DirectorySeparatorChar));

Example:

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

This can also be done like so;

var directoryName = System.IO.Path.GetFileName(@"c:\projects\roott\wsdlproj\devlop\beta2\text");

Based on previous answers (but fixed)

using static System.IO.Path;

var dir = GetFileName(path?.TrimEnd(DirectorySeparatorChar, AltDirectorySeparatorChar));

Explanation of GetFileName from .NET source:

> Returns the name and extension parts of the given path. The resulting > string contains the characters of path that follow the last > backslash (""), slash ("/"), or colon (":") character in > path. The resulting string is the entire path if path > contains no backslash after removing trailing slashes, slash, or colon characters. The resulting > string is null if path is null.

Path.GetDirectoryName(@"c:\projects\roott\wsdlproj\devlop\beta2\text");
