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.

I have a Path;
\\\\username-txd\location\Configuration\MediaManagerConfig\Web.config
I want to create a copy of file at one position up in the same folder i.e.
\\\\username-txd\location\Configuration\Web.config
Can anyone help me with the code since I am new to C#
DirectoryInfo.Parent returns this MediaManagerConfig and you can do little bit string manupalition like;
var di = new DirectoryInfo(#"\\\\username-txd\location\Configuration\MediaManagerConfig\Web.config");
Console.WriteLine(di.FullName.Replace(di.Parent.Name + Path.DirectorySeparatorChar, ""));
Result will be;
\\username-txd\location\Configuration\Web.config
If you want 4 back slash based on your result, your can replace with \\ to \\\\ as well.
You can use File.Copy to copy the file.
To get your destination file name, you can do
Path.Combine(Path.GetDirectoryName(Path.GetDirectoryName(path)), Path.GetFileName(path));
with 'path' the full path with the file name.
You need to import System.IO.
I would use seomthing like the power of the DirectoryInfo class. It knows the relationship on the filesystem and provides e.g. the .Parent property:
string originalFilename = "\\\\username-txd\\location\\Configuration\\MediaManagerConfig\\Web.config";
string originalPath = Path.GetDirectoryName(originalFilename);
string newPath = Path.Combine(new DirectoryInfo(originalPath).Parent.FullName, Path.GetFileName(originalFilename));
Basically I want to sub-string directory path for example path is "server/student/personal/contact"
I want to path like "/student/personal/contact". That's mean first folder name I don't want to in
in path. Every time this path is change by project requirement so how to remove first folder name
from string path.
problem that here in string path first Folder name not same name every time So please help for this how to remove first folder name from string path
Try this:
string strp = "server/student/personal/contact";
strp = strp.Substring(strp.IndexOf("/"));
Output:
/student/personal/contact
I usually write something like this
string example = "server/student/personal/contact";
var paths = example.Split('/').ToList();
if (paths.Any())
{
paths.RemoveAt(0);
}
string result = string.Join("/", paths);
or you can:
string example = "server/student/personal/contact";
var pos = example.IndexOf("/", System.StringComparison.Ordinal);
if (pos > 0)
{
example = example.Substring(pos);
}
you can simply do this :
string path = "server/student/personal/contact";
//IndexOf() gives you the first occurrence of the character.
int firstSlash=path.IndexOf('/');
string modifiedPath = path.Substring(firstSlash);
I want to cut out a part of a path but don't know how.
To get the path, I use this code:
String path = System.IO.Path.GetDirectoryName(fullyQualifiedName);
(path = "Y:\Test\Project\bin\Debug")
Now I need the first part without "\bin\Debug".
How can I cut this part out of the current path?
If you know, that you don't need only "\bin\Debug" you could use replace:
path = path.Replace("\bin\Debug", "");
or
path = path.Remove(path.IndexOf("\bin\Debug"));
If you know, that you don't need everything, after second \ you could use this:
path = path.Remove(path.LastIndexOfAny(new char[] { '\\' }, path.LastIndexOf('\\') - 1));
and finally, you could Take so many parts, how many you want like this:
path = String.Join(#"\", path.Split('\\').Take(3));
or Skip so many parts, how many you need:
path = String.Join(#"\", path.Split('\\').Reverse().Skip(2).Reverse());
You can use the Path class and a subsequent call of the Directory.GetParent method:
String dir = Path.GetDirectoryName(fullyQualifiedName);
string root = Directory.GetParent(dir).FullName;
You can do it within only 3 lines.
String path= #"Y:\\Test\\Project\\bin\\Debug";
String[] extract = Regex.Split(path,"bin"); //split it in bin
String main = extract[0].TrimEnd('\\'); //extract[0] is Y:\\Test\\Project\\ ,so exclude \\ here
Console.WriteLine("Main Path: "+main);//get main path
You can obtain the path of the parent folder of your path like this:
path = Directory.GetParent(path);
In your case, you'd have to do it twice.
How do you get the last folder/directory out of user-input regardless of if the input is a path to a folder or a file? This is when the folder/file in question may not exist.
C:\Users\Public\Desktop\workspace\page0320.xml
C:\Users\Public\Desktop\workspace
I'm trying to get out the folder "workspace" out of both examples, even if the folder "workspace" or file "page0320.xml" doesn't exist.
EDIT: Using BrokenGlass's suggestion, I got it to work.
String path = #"C:\Users\Public\Desktop\workspace";
String path2 = #"C:\Users\Public\Desktop\workspace\";
String path3 = #"C:\Users\Public\Desktop\workspace\page0320.xml";
String fileName = path.Split(new char[] { '\\' }).Last<String>().Split(new char[] { '/' }).Last<String>();
if (fileName.Contains(".") == false)
{
path += #"\";
}
path = Path.GetDirectoryName(path);
You can substitute any of the path variables and the output will be:
C:\Users\Public\Desktop\workspace
Of course, this is working under the assuption that files have extensions. Fortunately, that assumption works for my purposes.
Thanks all. Been a long-time lurker and first-time poster. It was really impressive how fast and helpful the responses were :D
use Path.GetDirectoryName :
string path = Path.GetDirectoryName(#"C:\Users\Public\Desktop\workspace\page0320.xml");
string path2 = Path.GetDirectoryName(#"C:\Users\Public\Desktop\workspace\");
Note the trailing backslash in the path though in the second example - otherwise workspace will be interpreted as file name.
I will use DirectoryInfo in this way:
DirectoryInfo dif = new DirectoryInfo(path);
if(dif.Exist == true)
// Now we have a true directory because DirectoryInfo can't be fooled by
// existing file names.
else
// Now we have a file or directory that doesn't exist.
// But what we do with this info? The user input could be anything
// and we cannot assume that is a file or a directory.
// (page0320.xml could be also the name of a directory)
You can use GetFileName after GetDiretoryName from the Path class in the System.IO namespace.
GetDiretoryName will get the path without the filename (C:\Users\Public\Desktop\workspace).
GetFileName then returns the last part of the path as if it is a extensionless file (workspace).
Path.GetFileName(Path.GetDirectoryName(path));
EDIT: the path must have a trailing path separator to make this example work.
If you can make some assumptions then its pretty easy..
Assumption 1: All files will have an extension
Assumption 2: The containing directory will never have an extension
If Not String.IsNullOrEmpty(Path.GetExtension(thePath))
Return Path.GetDirectoryName(thePath)
Else
Return Path.GetFileName(thePath)
End If
Like said before, there's not really a feasible solution but this might also do the trick:
private string GetLastFolder(string path)
{
//split the path into pieces by the \ character
var parts = path.Split(new[] { Path.DirectorySeparatorChar, });
//if the last part has an extension (is a file) return the one before the last
if(Path.HasExtension(path))
return parts[parts.Length - 2];
//if the path has a trailing \ return the one before the last
if(parts.Last() == "")
return parts[parts.Length - 2];
//if none of the above apply, return the last element
return parts.Last();
}
This might not be the cleanest solution but it will work. Hope this helps!
I have a method which is doing a file copy. The 'root' is specified by the user on the command line, which I sanitize with Path.GetFullPath(input).
I need to get the path of the file relative to that root, so the following cases would return:
Root FilePath Return
y:\ y:\temp\filename1.txt temp\filename1.txt
y:\dir1 y:\dir1\dir2\filename2.txt dir2\filename2.txt
You can write
var relative = new Uri(rootPath).MakeRelativeUri(new Uri(filePath));
http://msdn.microsoft.com/en-us/library/system.uri.makerelativeuri.aspx
string s1 = "y:\\";
string s2 = "y:\\temp\filename1.txt";
Console.WriteLine(s2.Substring(s1.Length)); \\ Outputs temp\filename1.txt
Hope this helps
Might want to call a .Trim() as well to ensure removing trailing \ characters or the like.
System.IO.Path.GetFullPath( filePath ).Substring( rootPath.Length )
string relativePath = Path.GetFullPath(input).Replace(rootPath, "");
