Simple question about arrays

Post by jacekm23 »

How can I define table of 256 bytes.

In C# I can write:

Byte[] data = new Byte[256];

In X#:

Local data as Byte[]
data := ?

Jacek,

In general you can change the C# code

new <type>(params)

to X# :

<type>{params}

so:

data := BYTE[]{256}

Hi Wolfgang,

Nice article. Maybe you should mention also that the old VO arrays use USUALs and makes the performance lower than that of typed .NET arrays.
And that at compile time you lack the checks of the compiler.
