brackets, braces and arrays

[bric]

Every time that I sit down to use an array I wonder a bit about
syntax. Even if it's a simple thing and I can just do it quickly and
get it out of the way.

The reason I wonder is this. (Most often I'm coding vb)

dim sTest(3) as string

is fine for grabbing my 4 test items.
But I've also gotten into the habit of doing this:

dim arParm as sqlparameter() = new sqlparameter(3){}

So are they both 2 ways of doing the same thing? Intellisense doesn't
give errors when I type a string array in this same manner as used
with the sqlparm.


And I recently noticed that in C# you do this:

string[] sTest = new string[3];

.... is this the corrolary for the vb syntax used above in my arParm
example?


And why the curly brackets at the end of the line? Are they ever used
for anything?

I figured I better ask this before too many years pass and I retire
without learning the basics.


thanks
Brian

The brackets at the end of the line can be used to initialize the array:

Dim arInt as Integer() = new Integer(3){0,1,2}

I had googled but a fresh search was useful. Thanks.

Thanks John.

And again, for interested others I found this:

which cleared up a few things.
