Get folder name from full file path

Question

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?

Answer 1

请参阅DirectoryInfo.Name ：

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

Answer 2

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;

Answer 3

Try this

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

Answer 4

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();

Answer 5

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"

Answer 6

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(@"\"));

Answer 7

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);

Answer 8

在这种情况下，您要获取的文件存储在 strpath 变量中：

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

Answer 9

也可以这样做；

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

Answer 10

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");
