how to get the Directory from Full path in C#?

Question

Hi,
i have a Full path as given below...

C:\Users\Ronny\Desktop\Sources\Danny\kawas\trunk\csharp\ImportME\XukMe\bin\Debug\DannyGoXuk.DTDs.xhtml-math-svg-flat.dtd

No i just want the DTDs directory to be fetched from this whole part?
Can i use String methods in this?
If yes then how to fetch this directory?

Thanks for your help.... Regards

Answer 1

Use System.IO.Path.GetDirectoryName() for the entire path, or new DirectoryInfo(path).Parent.Name for just the name of that one folder.

There is no directory named "DTDs" in the path you posted. IT looks like there's a file named "DannyGoXuk.DTDs.xhtml-math-svg-flat.dtd", but the periods (.) in that path are not valid directory separator characters. Did you mean "DannyGoXuk\DTDs\xhtml-math-svg-flat.dtd"?

If that's the case, given that entire new path, you want something like this to return a list of files in the DTDs folder:

string path = @"C:\Users\Ronny\Desktop\Sources\Danny\kawas\trunk\csharp\ImportME\XukMe\bin\Debug\DannyGoXuk\DTDs\xhtml-math-svg-flat.dtd";
string[] files = new DirectoryInfo(path).Parent.GetFiles();

in properties window i choose Build Type as Embedded resource.

And now we finally get to it. When you choose "Embedded Resource", the item is bundled into your executable program file. There is no direct path anymore. Instead, set your Build Type to "Content" and set "Copy to Output Directory" to "Copy Always" or "Copy if Newer".

Calling

System.IO.Path.GetFileName

with the full directory path returns the last part of the path which is a directory name. GetDirectoryName returns the whole path of parent directory which is unwanted.

If you have a file name and you just want the name of the parent directory:

var directoryFullPath = Path.GetDirectoryName(@"C:\DTDs\mydtd.dtd");  // C:\DTDs
var directoryName = Path.GetFileName(directoryFullPath);  // DTDs

Answer 3

System.IO.Path.GetFileName( System.IO.Path.GetDirectoryName( fullPath ) )

That will return just the name of the folder containing the file.

For

C:\windows\system32\user32.dll

this will return

system32

I'm inferring that that's what you want.

Answer 4

You can use:

System.IO.Path.GetDirectoryName(path);

Answer 5

You can use Path ...

Path.GetDirectoryName(myStr);

Answer 6

don't use string manipulation directly:

System.IO.Path.GetDirectoryName(myPath);

Answer 7

Use the FileInfo object...

FileInfo info = new FileInfo(@"C:\Users\Ronny\Desktop\Sources\Danny\kawas\trunk\csharp\ImportME\XukMe\bin\Debug\DannyGoXuk.DTDs.xhtml-math-svg-flat.dtd");
string directoryName = info.Directory.FullName;

The file doesn't even have to really exist.

Answer 8

Path.GetDirectory on the path you have specified returns:

"C:\Users\Ronny\Desktop\Sources\Danny\kawas\trunk\csharp\ImportME\XukMe\bin\Debug"

Try it yourself:

var path = Path.GetDirectoryName(@"C:\Users\Ronny\Desktop\Sources\Danny\kawas\trunk\csharp\ImportME\XukMe\bin\Debug\DannyGoXuk.DTDs.xhtml-math-svg-flat.dtd");

Your question is a little strange though- there is no directory called DTDs.

Answer 9

How bout this string manipulation trick...

string strFullPath = @"C:\Users\Ronny\Desktop\Sources\Danny\kawas\trunk\csharp\ImportME\XukMe\bin\Debug\DannyGoXuk.DTDs.xhtml-math-svg-flat.dtd";
string strDirName; 
int intLocation, intLength;

intLength = strFullPath.Length;
intLocation = strFullPath.IndexOf("DTDs");

strDirName = strFullPath.Substring(0, intLocation); 

textBox2.Text = strDirName;
