Store the name but not the path of all folders in a specified folder to a list?
So I have a folder in the same directory as my .exe console application. I want to make a list of all the folders inside of that folder (it's called ClientFiles ) but I don't want the full paths. So if I have a hierarchy like this:
ClientFiles
--- Folder1
--- Folder2
--- Folder3
I should end up with a list containing the strings: "Folder1", "Folder2", "Folder3".
This is what I have right now:
List<string> clientNumbers = Directory
.GetDirectories(AppDomain.CurrentDomain.BaseDirectory + "ClientFiles")
.ToList<string>();
but the list it's returning contains the full path for each element. Any quick way to resolve this? I guess I could foreach through and remove the preceding path text but that seems so extra.
There are a few ways that you can accomplish this.
The first is simply removing the component you already know:
string directory = AppDomain.CurrentDomain.BaseDirectory + "ClientFiles";
List<string> clientNumbers = Directory
.GetDirectories(directory)
.Select(x => x.Substring(AppDomain.CurrentDomain.BaseDirectory.Length - 1)
.ToList();
Assuming you only want the file's name (or folder's name if it's a folder object), you can use the Path class
List<string> clientNumbers = Directory
.GetDirectories(directory)
.Select(x => Path.GetFileName(x))
.ToList();
有了一点LINQ：
List<string> clientNumbers = System.IO.Directory.GetDirectories(AppDomain.CurrentDomain.BaseDirectory + "ClientFiles")
.Select(x => x.Replace(AppDomain.CurrentDomain.BaseDirectory + "ClientFiles", "")).ToList();
您可以在.Select(x=>x.Split('').LastOrDefault())添加.Select(x=>x.Split('').LastOrDefault()) ，例如：
List<string> clientNumbers = Directory.GetDirectories(AppDomain.CurrentDomain.BaseDirectory + "ClientFiles").ToList<string>()
.Select(x=>x.Split('').LastOrDefault());
