That depends on the format they are using, endiannes, width of bitfields for
float point numbers etc. Easiest would be if you could obtain a C reference
for data conversion from them. It'll be relatively simple to convert it to
C#.
In general a handy tool for conversions between simple data types is
Buffer.BlockCopy:

double[] a = new double[] { 1, 2, 3 };

byte[] b = new byte[Buffer.ByteLength(a)];

Buffer.BlockCopy(a, 0, b, 0, Buffer.ByteLength(a));

This converts an array of doubles into their memory representation as bytes.
Both target and source can be any of the basic types, like int, short,
double, even char.
