Siddharth Gajbhiye · Answer

array ^FileToByteArray(System::String ^_FileName) { array ^_Buffer = nullptr; try { // Open file for reading System::IO::FileStream ^_FileStream = gcnew System::IO::FileStream(_FileName, System::IO::FileMode::Open, System::IO::FileAccess::Read); // attach filestream to binary reader System::IO::BinaryReader ^_BinaryReader = gcnew System::IO::BinaryReader(_FileStream); // get total byte length of the file System::IO::FileInfo ^_FileInfo = gcnew System::IO::FileInfo(_FileName); System::Int64 _TotalBytes = _FileInfo->Length; // read entire file into buffer _Buffer = _BinaryReader->ReadBytes(safe_cast (_TotalBytes)); // close file reader _FileStream->Close(); delete _FileStream; _BinaryReader->Close(); } catch (Exception ^_Exception) { // Error Console::WriteLine( "Exception caught in process: {0}" , _Exception->ToString()); } return _Buffer; } HI There here is the code to convert file to bytearray and to reverse an array here is the code to reverse it /* Function to reverse arr[] from start to end*/ void rvereseArray( int arr[], int start, int end) { while (start { int temp = arr[start]; arr[start] = arr[end]; arr[end] = temp; start++; end--; } } You just need to call this function and thats it... if any query in the code please reply.. Thanku
