Why do I have to include an index?

Question

So I found this code online (usually I do C# however I'm trying to teach smallbasic to a friend of mine) that basically reads a file:

TextWindow.Write("Enter the name of the new directory: ")
DirectoryName = TextWindow.Read()
files = File.GetFiles(DirectoryName)        
TextWindow.WriteLine("This is the content in the file: ")   
TextWindow.WriteLine(File.ReadContents(files[1])) 

I understand what that all does, but why does it need to be files[1] instead of just files?

Removing the index [1] just makes the line not work, the program still compiles and whatnot.

SB doesn't have a debugger and the resources online aren't very good.

Answer 1

According to the API documents, File.GetFiles returns an array:

If the operation was successful, this will return the files as an array. Otherwise, it will return "FAILED".

You specify an index because it returns an array and File.ReadContents expects a single instance.
