Question

I’m just curious as to why I have to use the string[] when using Directory.GetDirectories()

string[] directories = Directory.GetDirectories("c:\\");

foreach (var dir in directories)
{
     Console.WriteLine(dir);
}

Why can’t I use

List<string> _directories = new List<string>();
        _directories = Directory.GetDirectories("c:\\");

Answer 1

Because GetDirectories returns a string[], basically.

Anyway, you can:

List<string> _directories = new List<string>(Directory.GetDirectories("c:\\"));

…or:

List<string> _directories = Directory.GetDirectories("c:\\").ToList();
