# Binary Pattern Search

Hi Everyone,\

```
namespace XYZ{    public partial class Form1 : Form {        StringBuilder bldr = new StringBuilder();        byte[] readFromFile;        Regex hexPattern = new Regex("0000000800(?<binaryText>.{16})");        MatchCollection matchBinary;        FileStream bStream = new FileStream("C:\\XYZ.bin", FileMode.Open, FileAccess.Read);        BinaryReader fruity;        public Form1() {            InitializeComponent();            using (fruity = new BinaryReader(bStream)) {                readFromFile = fruity.ReadBytes(31);            }            // create a hex-dump formatted string             // from the binary file input data             foreach (byte thisbyte in readFromFile) {                bldr.Append(thisbyte.ToString("x2"));            }            // then search the hex-dump-format string for the            // pattern he seeks. 'Capture' the eight bytes which            // follow the pattern.            matchBinary = hexPattern.Matches(bldr.ToString());            // No recovery required ... just index the data bytes            // in 'readFromFile' using the index supplied by Regex.        }// end constructor    }// end class Form1}// end Namespace ‘XYZ’
```
