Hello,
I need to support a file format that stores integers with the MSB first
and the LSB last. When I use
BinaryWriter aWriter = new BinaryWriter(aF ileStream, Encoding.ASCII) ;
int someValue = 1;
aWriter.WriteIn t32(someValue);
the byte stream that appears in the file is
01 00 00 00
What I need for this file format is
00 00 00 01
There does not appear to be anything in Marshal that supports this. Does
anyone have a recommendation?
Thanks in advance,

You could try using System.Net.IPAd dress.HostToNet workOrder to convert
the integer first....
using System;
using System.Net;
public class test
{
public static void Main ()
{
int i = 1;
int j = IPAddress.HostT oNetworkOrder (i);
Console.WriteLi ne (BitConverter.T oString (BitConverter.G etBytes (i)));
Console.WriteLi ne (BitConverter.T oString (BitConverter.G etBytes (j)));
}
}

You can also do by yourself with some bit shifting:
public void WriteInt32BigEn dian ( int value )
{
base.Write( new byte [0x4] {
(byte) (value >> 0x18),
(byte) (value >> 0x10),
(byte) (value >> 0x8),
(byte) (value)
} );
}

Looking at the language spec, I can't find a statement
about the byte order for value types, such as int, float,
etc. Are they guaranteed to be little-endian or big-
endian? I know that, on a little-endian machine, the byte
order is little-endian. But what if I run C# on a big-
endian machine, say, using Mono?
Does the C# language (or IL) make any guarantees as to the
byte order?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
