Help deciphering this line of code...

Dim bytes() As Byte = New Byte(1023) {}

If someone could help me understand this line of code (especially the part
to the right of the equal sign) I'd be much obliged...

re: Help deciphering this line of code...

It creates an array named bytes and initializes it with 1024(indicies 0-1023)
byte structures.

Piece by piece:

Dim bytes() - Dimension the variable bytes as an array
As Byte - of Byte structures
= New Byte(1023) {} - and initialize it to a newly created array of 1023
Bytes. Basically, the {} tells VB that this is a New array we are creating,
not a single instance of Byte. (1023) means that this new array has 1024
elements.

re: Help deciphering this line of code...

You can also initialize the array values as follows:

Dim bytes As Byte() = New Byte() {1,2,3,4,5,6,7,8,9,10}

This creates a byte array from index of 0 to 9 where the values are:

bytes(0) = 1
bytes(1) = 2
.......
bytes(9) = 10

Note when doing this, you can't specifiy the size of the array like (10)
since the size of the array is controlled by the number if values between
the {}

Terry,

In addition to the others, probably written from someone who converted C# to
VBNet.

Dim bytes(1023) as Byte

As we are used to do it.

the {} is an initialiser, the word New is what tells VB that this is a new
instance of a Type

The '{}' tells VB that it should create an array and don't call a
parameterized constructor of the class/structure. It must be specified
to remove ambiguity.

That's why I was confused. I looked at that and wondered why we couldn't
just do it the VB way. I thought maybe it created something completely
different.
