Dim s As [String] = [String].Emtpy

Dim s As [String] = [String].Emtpy

Is that a valid declaration in vb.net?

I see it in some example code in the msdn but I have no clue what the brackets are for. Can anyone enlighten me?

Also when you actually type the the statement, after you type "As [String]", the IDE removes the Brackes, so only way to do add this kind of declaration is to paste the whole thing and then it will stay.. Can anyone clue me in?

Not sure why you would need any brackets..... if it takes them off, then they are not needed.

Dunno why the MSDN shows them.... maybe just so you know it's a string? :confused:

it equates to this :

VB Code:

[COLOR=BLUE]Dim[/COLOR] s [COLOR=BLUE]As[/COLOR] [COLOR=BLUE]String[/COLOR] = [COLOR=BLUE]String[/COLOR].Empty

the [ ] get removed automatically if you type it with them in :)

He wanted to know why the MSDN showed code like that with the brackets, he already posted that VB automaticly takes them off....

yeah i overlooked that small detail lol:p
anyway , the [ ] are only there as you said , to show it's a string.

Hmm, I don't think it's just to "express" that it's a string because there are certain areas in the code where they have it.. As I said, you can actually paste the whole thing and it will work and the IDE will retain the brackets and it will act as a string. I'm thinking that this might have been something from beta or a earlier version of .Net that actually used the brackets.. see for yourself.. paste this into your browser and look at the code..

sorry, the first link was a local MSDN link.. works if you have 2003 msdn installed and IE on your machine :)

The brackets are used when a word can have two meanings in the current namespace. For instance if you want to use a shared method of the Enum class you'd have to use [Enum] or else it will think you are trying to declare an Enum. So either the example just used it to show it is using a member of the String class or something about the namespace made it be used.

VB Code:

<Flags()> _
    Enum QueryTypes
        [Select] = 1
        Insert = 2
        Update = 4
        Delete = 8
    End Enum
 
        Dim x As QueryTypes = [Enum].Parse(GetType(QueryTypes), "Insert")
        MsgBox(x.ToString)

Thank you Edneeis, that clears things up :)

Sweet! Just like in SQL. That's good to know. Thanks Edneeis! :)
