Im trying to cast a 4 byte array to an ulong in C#. I'm currently using this code:
atomSize = BitConverter.ToUInt32(buffer, 0);
The byte[4] contains this:
0 0 0 32
However, the bytes are Big-Endian. Is there a simple way to convert this Big-Endian ulong to a Little-Endian ulong?
In .net core (>= 2.1), you can use this instead:
BinaryPrimitives.ReadUInt32BigEndian(buffer);
That way, you're sure of the endianness you're reading from.
It's implemented there in case you're wondering how it works
Edit: as mentionned by @smkanadl in the comments, it seems that you can use this API as well in .net framework by installing the System.Memory package.
