What the square brackets mean in vb.net on this line

Question

What do the square brackets in vb.net mean in this variable below, defining it as [String]

Dim client As New WebClient()
Dim htmlCode As [String] = client.DownloadString("http://www.stackoverflow.com")

Answer 1

In your example, this is useless. Reserved keywords are used in parentheses to ensure that they are not, for example

Dim [String] = "asdf"

which will create a variable called "String" (which is silly, but ...)
