How to convert this in C to a TByteDynArray

I need to send Hex values to a C DLL file as a Byte Array.  So how would I
store the example below in a TByteDynArray?

unsigned char sampleString[35] =
{
0x53, 0x65, 0x63, 0x75, 0x72, 0x65, 0x20, 0x53, 0x65, 0x72, 0x76, 0x69,
0x63, 0x65,     0x73, 0x20, 0x43, 0x6F, 0x72, 0x70, 0x20, 0x2D, 0x20, 0x53,
0x48, 0x41, 0x50, 0x45, 0x20, 0x4C, 0x69, 0x6E, 0x78, 0x21, 0x00} ;


Thanks
