How to write array to memory?

[E1M1]

Following code would write "something" in memory address, but how do I write array to memory so that it would be still array. I need to convert it to binary somehow?

#include <WinAPI.au3>
#include <Memory.au3>
$null = ""
$hProcess = _WinAPI_OpenProcess(0x001F0FFF, False, ProcessExists("c.exe"))
$struct = DllStructCreate("char[255]")
DllStructSetData($struct, 1, "something")
$alloc = _MemVirtualAllocEx($hProcess, "", DllStructGetSize($struct), $MEM_COMMIT, $PAGE_READWRITE)
_WinAPI_WriteProcessMemory($hProcess, $alloc, DllStructGetPtr($struct, 1), DllStructGetSize($struct), $null);
