❔ Data Parsing

Hello,I'm trying to built a simulation program by using windows forms application and I have a question:I want to parse a byte array bit by bit by using struct method and udp protocol.But I couldn't figure out how I can parse the byte array bit by bit.If someone can help I would appreciate it

What does "parse bit by bit" mean in your scenario?

most of the data I'm gonna parse is 1 bit length so ı need a way to parse byte array but each bit individually so that I can parse all the data I need I don't know If I'm able to tell what I'm trying to say 🙂

Typically if you want to work with individual bits you would create a mask containing the bit you want to examine and then use bitwise and (the & operator) to test if that bit is set.

int mask = 1;
byte val = 100;

for (int i = 0; i < 8; i++)
{
    int bit = (val & mask) == 0 ? 0 : 1;
    Console.Write(bit);

    mask <<= 1;
}

int mask = 1;
byte val = 100;

for (int i = 0; i < 8; i++)
{
    int bit = (val & mask) == 0 ? 0 : 1;
    Console.Write(bit);

    mask <<= 1;
}

Console Output

ok here you compartmentalize the data for specific byte value and within that value all the bits right ?

mtreit•2y ago

That code just walks the bit pattern from least significant bit to most significant bit (right to left, if you want to think of it that way) and outputs the bit value.

I understand

The opposite direction:

there's the BitArray class if you want to read the bits one by one
