Java code - negative byte in byte array to C#

Question

In Java I have the following line:

new byte[]{59, 55, 79, 1, 0, 64, -32, -3};

However, in C# I can't use negative bytes in a byte array. I tried casting it to byte and it failed. What can I do? thanks!

Answer 1

Because in C# bytes are unsigned. In Java, bytes are signed.

From Byte Structure

Byte is an immutable value type that represents unsigned integers with values that range from 0 (which is represented by the Byte.MinValue constant) to 255 (which is represented by the Byte.MaxValue constant)

From Primitive Data Types

The byte data type is an 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127

What can I do?

You can use sbyte in C# which represents 8-bit signed integer.

The SByte value type represents integers with values ranging from negative 128 to positive 127.

Like;

sbyte[] sb = new sbyte[] {59, 55, 79, 1, 0, 64, -32, -3};
