Algorithm for sbyte?

Dear All,

Does anyone know the algorithm used to convert to an sbyte like follows? It
is not a straight hex conversion.

sbyte.Parse("B2 ", System.Globaliz ation.NumberSty les.HexNumber, null);

Any help is appreciated. Thanks and have a great day!

Cheers,
Rich

It is a straight hex conversion and ends up storing the same binary value in
the byte as it would in an unsigned byte. Its how the binary value is then
interpreted as a number. The top bit being set indicates its a negative
number in signed byte.

The algorithm is called 2's complement. See:-

After downloading and using two different memory profiling applications today, it seems that sbyte, int16, and int32 are all stored using 12b of memory. Someone please tell me I'm reading these memory profilers wrong! If I'm really reading it correctly, then what's the point of using anything other than a 32 bit integer? If they're all going to be stored the same way, then I can't achieve any memory savings(which I was really hoping for) by...

I need to convert a byte to an sbyte - and it has to preserve the original binary meaning of the 8 bits. For example - a 1111 1111, which is interpreted as byte to be 255, should show up in the sbyte as -1. The BitConverter class only takes 2 byte arrays or larger, and the Convert.ToSByte simply throws an overflow error. Any ideas? Thanks, Ray Ackley

I am using binary writer to write an array of bytes to disk. However, my data starts out as an array of sbytes. I am currently type casting each array element in a for loop. Is there a faster method for converting an array of sbytes to an array of bytes? Thanks, Darrel

I am attempting to pass an SByte to another .NET class that expects the data to be passed as SByte *. I searched around and found the boxing can be used to produce a pointer but I'm not sure if this is appropriate. I am using the following sequence: // Load class Assembly c = Assembl.LoadFrom("filename ....); // Get the types cTypes = c.GetTypes();

Hello i'm just starting out with csharp. and am trying to figure out why an sbyte can take any value from '-128' to 128. i've drawn a BIT box with eight bytes, and I'm assuming the eighth bit is used to SIGN the number, which leaves seven bits. when all 7 bits are on you get : 127 so i was assuming the most you can get negative would be 127, and the
