Compare 2 Files Byte for Byte

Question

Hi All Trying to figure out a way to compare 2 files byte for byte and capture/return the decimal offset/location of each difference. I've looked at binaryreader and streamreader but really am unsure how to read and compare. Any tips? Thanks

If the files are not too big then something like this should work: using System; using System.IO; using System.Collections.Generic; class BinaryCompare { static void Main() { byte[] bytes1 = File.ReadAllBytes(file1.bin); byte[] bytes2 = File.ReadAllBytes(file2.bin); List diffs = new List (); int minLen = Math.Min(bytes1.Length bytes2.Length); int maxLen = Math.Max(bytes1.Length bytes2.Length); for(int i = 0; i { if( bytes1[i] != bytes2[i]) diffs.Add(i); } if(maxLen > minLen) { for(int i = minLen; i } // do something with diffs } }
