I Get list of files listed in a folder called Book like this

string[] files = Directory.GetFiles("Book");

and I put these files name as button texts in my app . buttons texts get like this :

Book\1.mp3
book\2.mp3

I want to remove this Book\ from texts. How can I do that?

Answer 1

If you want to get to the names:

string[] files = new DirectoryInfo("Book").GetFiles().Select(f => f.Name).ToArray();

I don't know how much overhead getting the directoryinfo really would introduce. But if it seems overkill as suggested you can use Path.GetFileName.

Answer 2

If you just want the filename then you can use Path.GetFileName

Answer 3

You can use Path.GetFileName to get the file name from the path. Here is the example

string filename = Path.GetFileName(@"Book\1.mp3");

here in filename you will get 1.mp3

Answer 4

Assuming the directory is always called "Book":

string[] files = Directory.GetFiles("Book").Select(f => f.Substring(5));

This will strip out the beginning of the text ("Book\") leaving you with just the file name itself.

Answer 5

As you got the names from Directory.GetFiles so the return list is obviously file paths. You can separate the file name from a path or relative path using following api

string name = Path.GetFileName(@"\Book\test.mp3");

it will give you test.mp3 in return. See detail about Path.GetFileName

Answer 6

using Replace funciton

 files[0].Replace("Book\","");
    files[1].Replace("Book\","");

Use for loop
