Will the ID of a byte affect the size too?

Hello Codeproject,

Assuming I have two bytes:

C#

byte One = 0;
byte Two = 1;

If I save these, will One be less than two since the byte value itself is less? I mean, everything is written in bitcode. But are all the bits of the bytes the same length such as:

C#

bit One = 010101;
bit Two = 011101;

Or would it be more like this:

C#

bit One = 010;
bit Two = 010011;

I'm not sure if I'm able to ask this in an understandable way but, do bytes have different bitlengths?

"ID of a byte" means only one thing: gibberish:

You are confusing bytes with strings representing bytes. This is very frustrating. The only one thing can come: learn some computing from the very beginner. Answering your particular question won't help you. Instead, you should understand how data is represented in principle, how variables and types work, what .NET does, what the language and a compiler do. Right not, you don't have a clue.

Any value will be padded with 0's (for a positive or unsigned number) or 1's (for a negative signed number) to fit the size of the value it's in (8 bits for bytes, 16 for short, etc.).

Solution 1

A value typed as byte will always use at least 8 bits: Integral Types Table (C# Reference)[^].

I think it will always use exactly 8 bits, no?

Not always, since a compiler can always choose the optimal representation. Sometimes using word or double word aligned bytes can cause a significant performance gain. It all depends on how the byte is supposed to be used. There is an attribute called SequentialLayout that also plays a role in how a compiler may be constrained in optimizing an internal representation of a value.
