BinaryReader Question

Trying to read the values AS bytes, but reader reads them as decimals, is there a trick to making it bytes?

        private void ReadArenaDefs(string arenaSlotNumber)
        {
            string fileName = @$"{AppDomain.CurrentDomain.BaseDirectory}\ArenaDefinition_00505.jsfb";
            
            byte[] bytesCrowdType = new byte[8];
            int offset = 288;

            if (File.Exists(fileName)) 
            {
                using (BinaryReader reader = new BinaryReader(new FileStream(fileName, FileMode.Open)))
                {
                    reader.BaseStream.Seek(offset, SeekOrigin.Begin);
                    reader.Read(bytesCrowdType, 0, 8);          
                }    
            }  
        }

        private void ReadArenaDefs(string arenaSlotNumber)
        {
            string fileName = @$"{AppDomain.CurrentDomain.BaseDirectory}\ArenaDefinition_00505.jsfb";
            
            byte[] bytesCrowdType = new byte[8];
            int offset = 288;

            if (File.Exists(fileName)) 
            {
                using (BinaryReader reader = new BinaryReader(new FileStream(fileName, FileMode.Open)))
                {
                    reader.BaseStream.Seek(offset, SeekOrigin.Begin);
                    reader.Read(bytesCrowdType, 0, 8);          
                }    
            }  
        }

Just read the bytes directly from Stream You don't need BinaryReader, that's for reading bytes as other types

Core DreamOP•3y ago

hmm but the issue i have is it comes back as decimals

Core DreamOP•3y ago

is there a way to convert it to bytes in the bytes[] array or it has to be .ToString("X") for that?

reacher•3y ago

It is bytes It's just displayed as base 10 Everything is bytes internally That's just how the debugger is configured to display them

Core DreamOP•3y ago

ah Is there a way to turn them into this? 732B2BDED5BB0FCA which is those in hex

reacher•3y ago

Probably, google "visual studio debugger hex"

Core DreamOP•3y ago

ty wait, so if i put it to "RELEASE" it will show hex? in my form

reacher•3y ago

Why would release have anything to do with anything?

Core DreamOP•3y ago

DebugOutputContent.Text = fs.Read(bytesCrowdType, 0, bytesCrowdType.Length).ToString("X"); Because I want the USER to see hex no one makes games or mods or does stuff in base 10 🙂 even in Unity I just suck at this I guess 😦

reacher•3y ago

Release doesn't have anything to do with how you format things to display to the user But yes if you want to display a hex string to the user you have to convert the bytes to a hex string like that

Core DreamOP•3y ago

foreach (byte b in bytesCrowdType) { DebugOutputContent.Text += b.ToString("X"); } got it 🙂 Thank you for putting up with my dumb question I appreciate your time and help Also the new help post system is amazing 🙂

reacher•3y ago

Yeah I kinda like it lol It's nice

Core DreamOP•3y ago

Yeah Discord did g ood on that front 🙂 Last question based on 'writing' bytes (fs i guess) don't worry if its not hex then right? it will convert to hex in file?

reacher•3y ago

If you want to write bytes you write bytes from a byte array Make sure you don't write a string

        private void WriteArenaDefs(string arenaSlotNumber)
        {
            string fileName = @$"{AppDomain.CurrentDomain.BaseDirectory}\ArenaDefinition_00505.jsfb";

            byte[] bytesCrowdType = new byte[8];

            int offset = 288;

            if (File.Exists(fileName))
            {
                using (FileStream fs = File.OpenWrite(fileName))
                {
                    for (int i = 0x120; i <= 0x127; i++)
                    {
                        fs.Position = offset;
                        fs.Write(bytesCrowdType);
                    }
                   
                    fs.Close();
                 
                }
            }
        }

        private void WriteArenaDefs(string arenaSlotNumber)
        {
            string fileName = @$"{AppDomain.CurrentDomain.BaseDirectory}\ArenaDefinition_00505.jsfb";

            byte[] bytesCrowdType = new byte[8];

            int offset = 288;

            if (File.Exists(fileName))
            {
                using (FileStream fs = File.OpenWrite(fileName))
                {
                    for (int i = 0x120; i <= 0x127; i++)
                    {
                        fs.Position = offset;
                        fs.Write(bytesCrowdType);
                    }
                   
                    fs.Close();
                 
                }
            }
        }

so like this someone told me you needed to loop through each byte in the array too

reacher•3y ago

Why are you seeking and writing one byte at a time? Just seek once and write the whole array?

Core DreamOP•3y ago

I am not sure how to do that with writing fs.Position = offset; fs.Write(bytesCrowdType); ah think i got it
