C# equivalent of Python's pack/unpack and sum?

Is there any function equivalent to Python's struct.pack and struck.unpack in C# that allows me to pack and unpack values like this?

comman_type = 1
command_class=5
command_code=0x14
arg0=0
arg1=0

packed_message = pack('<bBBii',comman_type,command_class,command_code,arg0,arg1)
cs = sum(unpack('bbbbbbbbbbb',packed_message)
packed_message =   pack('<bBBiib',comman_type,command_class,command_code,arg0,arg1,cs)

I have an array of type char which contains the same data which are at the top on the python code.C#

List<char> tx_buffer2 = new List<char>();

(char message_Type, byte Command_Class, byte command_code,Int32 argument1, Int32 argument2)
Exemple array
('1', 1, 0x22, 1 , 0)

and I want to convert to bytes that respect the format present in pack and unpack function and the sum method

    Hi QuatreHuit-1669,
    The closest equivalent would probably be to use BinaryWriter writing into a MemoryStream, or BitConverter for a one-off conversion of a single value into a byte array.
    xanatos provided a code example in this thread you can refer to.
    Besides,fdmillion wrote a own class to achieve it in this thead which is useful for you.
    Best Regards,
    Daniel Zhang
