Converting byte array to short array?

Ole
Hi,

Is there a better / faster way to convert a byte array to a short array than
to use Convert.toInt16(bytearray, i) in a loop?

Thanks
Ole

It depends .. do you want 1 short per byte or a byte represents a high and
low of a short .. if the second then try Buffer.BlockCopy().

Yes. Don't call the Convert.ToInt16 method, it's not needed when you
convert a byte to a short. All it does is:

public static short ToInt16(byte value)
{
return value;
}

As to the loop, it can't be avoided. As a byte and short are of
different size, you can't copy the data using any block copy method.
