Do you have an example, please? Because I'm lost :x

❔ Read bits from a byte[] array

For example, if I then want to read 3 bits from my byte stream, the ReadInt32BigEndian method won't advance the stream by 4 bytes, do you understand?

❔ Read bits from a byte[] array

Yes, it works, but I can't read several values in my byte stream

❔ Read bits from a byte[] array

Yes, except that there's no lib capable of reading a byte stream in little endian :/

❔ Read bits from a byte[] array

I get 0x00000035 when using MemoryStream + BinaryReader and 0x35000000 when using BitStream

BitStream reads big endian data https://github.com/Sewer56/Sewer56.BitStream/issues/2

❔ Read bits from a byte[] array

To keep things simple, the server will write a int32 at the beginning of the packet, which I must read to retrieve the value

❔ Read bits from a byte[] array

I need to read negative values in the header variable because basically the packet id can be -1, -3 etc

❔ Read bits from a byte[] array

// I get two different results here
// I would like to obtain the same result as header2 in header 1
var header1 = bitStream.Read32(32);
var header2 = BitConverterToInt32(binReader.ReadBytes(4));

// I get two different results here
// I would like to obtain the same result as header2 in header 1
var header1 = bitStream.Read32(32);
var header2 = BitConverterToInt32(binReader.ReadBytes(4));

❔ Read bits from a byte[] array

Yes, I get the same behavior, but from the moment I start reading 4 bytes I don't get the same values

❔ Read bits from a byte[] array

I think it's a cast problem, yes, because in my code there are conditions that check whether the header variable corresponds to something and I never get to that condition, whereas if I use MemoryStream + BinaryReader it works

❔ Read bits from a byte[] array

Okay, but why get a different value in the console? If I use MemoryStream + BinaryReader or something else, I'll get the same values, but smaller

❔ Read bits from a byte[] array

Basically I have this:

public static void Parse(byte[] buffer)
{
  var stream = new ArrayByteStream(buffer);
        
  var bitStream = new BitStream<ArrayByteStream>(stream);

  // Reads 4 bytes and advances the position by 4 bytes
  var header = bitstream.ReadInt32();
        
  // Read 3 bits and advance position by 3 bits
  var subchanIndex = bitstream.ReadBits(3);
}

public static void Parse(byte[] buffer)
{
  var stream = new ArrayByteStream(buffer);
        
  var bitStream = new BitStream<ArrayByteStream>(stream);

  // Reads 4 bytes and advances the position by 4 bytes
  var header = bitstream.ReadInt32();
        
  // Read 3 bits and advance position by 3 bits
  var subchanIndex = bitstream.ReadBits(3);
}

Except that the values I get are much larger than if I use MemoryStream + StreamReader

❔ Read bits from a byte[] array

Basically, I have a UDP client that must read packets sent to me by a UDP server In the stream I receive, I have to read both integers and bits In C#, we can only read bytes in a stream

❔ Read bits from a byte[] array

Yes, I know that we can read an int32 natively EXCEPT that in the rest of my code I have to read bits and we can't do that natively

❔ Read bits from a byte[] array

Thanks for your answer In the library, using Read<int>() means that I want to read 32 bits (4 bytes), and advance the position by 4 bytes.
