Write Byte Array to File

How to write byte array to file ?
Ans :
//writeByteArrayToFile : This function write byte array to the file
        public bool writeByteArrayToFile(byte[] f_arData, string f_stFilePath)
            //create response flag for notify the calling function about status
            //default value set to false
            bool l_blResponse = false;
                //Create FileStream instance in ReadWrite
                FileStream l_FileStream = new FileStream(f_stFilePath, FileMode.Create, FileAccess.ReadWrite);
                //Create BinaryReader Instance with open filestream instance
                BinaryWriter l_BinaryWriter = new BinaryWriter(l_FileStream);
                //Wriete Bytes to the file
                //Just need to close open streams
                //set Response Falg to true
                l_blResponse = true;
            catch (Exception ex)
                //If we have any exception then just write message to console
            //return response to the calling funciton
            return l_blResponse;


Read Byte Array From File

 //ReadByteArrayFromFile : This function read file from FilePath
        public byte[] ReadByteArrayFromFile(string f_stFilePath)
            //Create Data array
            byte[] l_arData = null;
            //Create FileStream instance in Read mode
            FileStream l_FileStream = new FileStream(f_stFilePath, FileMode.Open, FileAccess.Read);
            //Create BinaryReader Instance
            BinaryReader l_BinaryReader = new BinaryReader(l_FileStream);
            //Calculate Total Number of bytes to be read
            long l_nmTotalBytes = new FileInfo(f_stFilePath).Length;
            //Read Bytes Using BinaryReader Instance
            l_arData = l_BinaryReader.ReadBytes((int)l_nmTotalBytes);
            //Now we have data in DataArray so, just need to close open streams
            //return Data array to the calling function
            return l_arData;

Convert char Array To String

//Take one sample string data
String l_stData = "Hello how are you";

//convert into character array
char[] l_arData = l_stData.ToCharArray();

//Lets convert back to string
l_stData =  new String(l_arData);
