Default Variable Differences

Hello Everyone and thanks for your help in advance. I am working on a file browser from an ASP.Net page. When I come across examples of recursing through the files in a directory, most of the examples have something like:

Dim Files() As String
Files = Directory.GetFiles(myDirectory)

My question is, what is the difference between:

Dim Files As String and Dim Files() As String

It appears that Files() is some sort of array, but I am not clear on this. Any insight on this owuld be greatly appreciated. Thanks.

Well, you can declare an array of any object. Despite it's name, "Files" is a single string whereas "Files()" is an array of strings. Simply put, you should be able to give any variable the trailing () and create an array of them.

Here's the thing that will really twist your noodle:

What's the difference between

    Dim Files() As String
        and
    Dim Files As String()

They do the same thing but I've always wondered if there is a difference. Perhaps it's just a flexibility in VB of where you can specify the variable as an array. It's frankly a poor "feature" because using the "String()" kind of implies a constructor. When used in this case, it certainly isn't one.
