The closest I get is using new FileInfo(path).FullPath, but as far as I know FileInfo is for files only, not directory.

See also my comments to Jon Skeet's answer here for context.

    Add some examples. It's not clear what you want. – H H Oct 25 '11 at 09:01

    @@LouisRhys - What exactly is your question? The linked question does not tell me what you are looking for. You should be using **FileSystemInfo** and determine if its a File or a Directory. You keep trying to find faults in the provided answers without explaining the reasons. – Security Hound Oct 25 '11 at 11:57

The Path class also gives you a lot of nice methods and properties, e.g. GetFullPath(). See MSDN for all details.

Use the DirectoryInfo class for paths to directories. Works much in the same matter as FileInfo.

Note that the property for the path is called FullName.

DirectoryInfo di = new DirectoryInfo(@"C:\Foo\Bar\");
string path = di.FullName;

If you want to determine whether a path is a file or a directory, you can use static methods from the Path class:

string path1 = @"C:\Foo\Bar.docx";
string path2 = @"C:\Foo\";

bool output1 = Path.HasExtension(path1); //Returns true
bool output2 = Path.HasExtension(path2); //Returns false

However, paths could also contain something that might resemble an extension, so you might want to use it in conjunction with some other checks, e.g. bool isFile = File.Exists(path);

  • what if it's a file, not directory? – Louis Rhys Oct 25 '11 at 09:06
  • You really need to distinguish between when you want the path for a directory or when you want the path for a file. As far as I know, there is no generic "Path" class, to represent either a file or a directory. – Lars Kristensen Oct 25 '11 at 09:09

You can use file.getdirectory to get this done.

I think it's-

DirectoryInfo.FullName

Try this:

String strYourFullPath = "";
IO.Path.GetDirectoryName(strYourFullPath)

  • It doesn't return the full path – Louis Rhys Oct 25 '11 at 09:06
  • It does. when strYourFullPath is a file, then it returns the directory where it file is in, when its strYourFullPath is a directory, its stays the same. If this is not what you are looking for, then what are you trying to achive? – Vincent Van Eijsden Oct 25 '11 at 10:46

Use the DirectoryInfo class which extends FileSystemInfo and will give the correct result for either files or directories.

        string path = @"c:\somefileOrDirectory";
        var directoryInfo = new DirectoryInfo(path);
        var fullPath = directoryInfo.FullName;

According to msdn, FileSystemInfo.FullName gets the full path of the directory or file, and can be applied to a FileInfo. 

FileInfo fi1 = new FileInfo(@"C:\someFile.txt");
Debug.WriteLine(fi1.FullName); // Will produce C:\someFile.txt
FileInfo fi2 = new FileInfo(@"C:\SomeDirectory\");
Debug.WriteLine(fi2.FullName); // Will produce C:\SomeDirectory\
