Int to Byte Array

Question

Hey guys,
Int to Byte Array, please!?!

The byte array needs to be a fixed size of 4.

array<Byte> ^byte = gcnew array<Byte>(4);

and should be padded with 0x00's

So if the incoming int = 18, I want the byte array to look like
{ 0x00, 0x00, 0x00, 0x12 }

Thanks!

See BitConverter.GetBytes Method (Int32):

Answer 2

Alex,
That looks like what I need.  Can the BitConverter be forced to put the parameter-to-be-converted into the LSB position rather than MSB???
For examp, when I convert an int = 18, i get

{ 0x12, 0x00, 0x00, 0x00 }

How can i get

{ 0x00, 0x00, 0x00, 0x12 }

Answer 3

Found it!!!

UInt32 arg = 18;
array<Byte>^byteArray = BitConverter::GetBytes( arg);
// {0x12, 0x00, 0x00, 0x00 }

byteArray->Reverse(byteArray);
// { 0x00, 0x00, 0x00, 0x12 }
