What is the difference between Dim s As String and Dim s As [String]?

Question

What's the difference between:

Dim s As String

and

Dim s As [String]

Answer 1

There is no difference.

In VB, you can wrap the identifier in parentheses to make it be parsed as an identifier, not a keyword.

For example, you can write

Dim [If], [As], [Dim]

without any syntax errors.

The brackets have no effect, except to indicate that the identifier is not a keyword, someVarand therefore [someVar]identical.

Answer 2

Technically, there is no difference. Dim s As Stringcoincides withDim s As [String]

Answer 4

There are no functional differences in the hosted code.

You can use square brackets to declare a variable with the same name as the VB.NET keyword. Given a variable named "Loop" (reserved keyword in VB):

Loop.Visible = True 'Causes an error.
[Loop] .Visible = True 'Sets the Visible property of the variable named "Loop".

This example is provided on the MSDN page in the subject .
