C# two bytes to int
WebBut I need to convert them into an usable int variable. For example, 02 00 00 00 = 2 So far, I have this code to convert the first 2 bytes: (I used FileStream.Read to store the raw datas into a buffer variable) int num = ( (buffer [5] << 8) + buffer [4]); But it will only convert the first two bytes. (02 00 in the example, not 02 00 00 00) WebOct 14, 2009 · 7. Is suspect that the line: byte b = BIT_ZERO_SET BIT_ONE_SET; is actually processed by the C# compiler into an assignment of a constant value to b, rather than a bitwise operation - it can do this because the right side of the expression is fully defined at compile time. The line: //b = b BIT_TWO_SET;

WebJan 12, 2012 · public static unsafe byte[] GetBytes(int value) { byte[] buffer = new byte[4]; fixed (byte* bufferRef = buffer) { *((int*)bufferRef) = value; } return buffer; } Which from my point of view is more clean and seems faster than making 1 integer + 4 byte assignments to a explicit struct as this one. WebWe can use another approach without bit shift to convert bytes to short without shift by using java.nio.ByteBuffer. ByteBuffer bb = ByteBuffer.allocate(2); bb.order(ByteOrder.LITTLE_ENDIAN); bb.put(nTempByteArr[1]); bb.put(nTempByteArr[0]); short shortVal = bb.getShort(0); and we can use the get function of ByteBuffer will help …
WebJun 3, 2009 · 16 Answers. So, there is no + operation on bytes, bytes are first cast to integers and the result of addition of two integers is a (32-bit) integer. that is because there is no + operation for bytes (see above). Try byte z = (byte) ( (int) x + (int) y) This has got to be the most correct, concise answer.
