One way to determine whether two files are identical is to compare the files byte-by-byte. The following method uses this approach to determine whether two files are identical:
// Return true if the files are identical.public static bool FilesAreIdentical(FileInfo fileinfo1, FileInfo fileinfo2){ byte[] bytes1 = File.ReadAllBytes(fileinfo1.FullName); byte[] bytes2 = File.ReadAllBytes(fileinfo2.FullName); if (bytes1.Length != bytes2.Length) return false; for (int i = 0; i < bytes1.Length; i++) if (bytes1[i] != bytes2[i]) return false; return true;}
This method uses the File class's ReadAllBytes method to read the two files into byte arrays. If the arrays have different lengths, then the files are not identical, so ...
