Convert byte array to int

Question

I am trying to do some conversion in C#, and I am not sure how to do this:

private int byteArray2Int(byte[] bytes)
{
    // bytes = new byte[] {0x01, 0x03, 0         


        

Answer 1

A fast and simple way of doing this is just to copy the bytes to an integer using Buffer.BlockCopy:

UInt32[] pos = new UInt32[1];
byte[] stack = ...
Buffer.BlockCopy(stack, 0, pos, 0, 4);

This has the added benefit of being able to parse numerous integers into an array just by manipulating offsets..
