Storing names in array without path

Question

I have following code that reads folder names given a path.

string[] dirNames =(Directory.GetDirectories(@"c:\test\project\"));
foreach(string name in dirNames)
{
   Console.WriteLine(name);
}

Problem is that dirNames array is storing the directory name with path. While I just want to store the directory file name no path. I can remove it in the foreach loop but I want to store originally in the array with out path. Please let me know how to fix it. Thanks

Answer 1

Use GetDirectoryName from the Path class:

  foreach(string name in dirNames)
  {
      Console.WriteLine(Path.GetDirectoryName( name ));
  }

Answer 2

What about:

string[] dirNames = Directory.GetDirectories(@"c:\test\project\").Select(x => Path.GetDirectoryName(x)).ToArray();

Answer 3

You can get a new array (or list) in which the path is removed:

var dirNamesNew = dirNames.Select( x => x.Replace(path,"")).ToArray();

or in a single instruction:

string[] dirNames = (Directory.GetDirectories(path)).Select(x => x.Replace(path,"")).ToArray();

the Select will fetch the names, replace the path with no character, and then convert it back to an Array.

Answer 4

Try creating a DirectoryInfo and projecting the name for each directory:

var onlyDirectoryNames = Directory.GetDirectories(@"c:\test\project\").Select(x => new DirectoryInfo(x).Name)
