Bitconverter.getbytes reverse order

Copy if you are handling byte array. Using Linq is an overkill in terms of GC for such an easy low level task. It would be the hell slower and creates hundreds of garbage bytes on heap. Marc Gravell Marc Gravell k gold badges silver badges bronze badges.

I know BitConverter assumes little-endian, so your first example would be needed if he was going to pass the result to BitConverter. ToInt32 tempForTimestamp, 0 ; but if he just wanted the int value, then wouldn't he just not use the bit shifts??? Big-endian CPUs exist and can run. If you want t check: query BitConverter. IsLittleEndian — Marc Gravell. Goku what is array1? The details really, really matter here , so we need to be very explicit.

Also, it isn't true to say that Windows is strictly little-endian. Remember Itaniums? Now, when we're assigning an integer the entire point is that how that is implemented internally is masked from us unless we look beneath the covers. Integers on big and little endian CPUs behave identically in most ways, including shift operators. It is only when we do re-interpret casts unsafe thunks, etc that Which basically means: serializers and interop code. Or things using SIMD.

I was wrong, I played around some more in a console app and completely forgot that if I shift and OR, the other byte being compared to is padded with 0s ON THE LEFT before doing the comparison this lead to some bad assumptions from weird results. Sorry for the sloppy comments, I'll delete them so they don't confuse someone else — Goku. Add a reference to System. Memory nuget and use BinaryPrimitives.

Good answer. M Granja M Granja 8 8 silver badges 26 26 bronze badges. IsLittleEndian return BitConverter. ToInt16 BitConverter. Skip offset. Take 2. ToArray : data, 0 ; return BitConverter. Found a bug in the previous code in that the arrays were being reversed, but the starting index was not, resulting in non-obvious behavior.

I fixed that for all but the ToString methods. Expand Embed Plain Text. Copy this code and paste it in your HTML. Generic ;. Linq ;. Text ;. This implementation. GetBytes value ;. GetBytes value.
