Get folder name from full file path

Question

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(@"\"));
