// we uses BinaryFormatter and FileStream for serializing a double array and connecting it into a file.
// Just create FileStream and Binaryformatter objects and connect with each others.

BinaryFormatter bf = new BinaryFormatter();  // creates a BinaryFormatter object
FileStream fs = new FileStream("C:\\bin.dat", FileMode.Create); // Creates a FileStream Object which handles file creations.
bf.Serialize(fs, doubleArrayWillBeSaved ); // double array is serialized and saved into a file. BinaryFormatter serializes double array and send it to FileStream. Then Filestream save it into a file, "bin.dat".

// In de-serializing, we uses same classes, BinaryFormatter and FileStream.
// But just call Deserialize function for deserializing.
// If you understand the previous example, this example is easy to understand.
// Deserialize function returns the object which has double array we saved.
// The program doesn't know what it is, but we know. So we teach the program what it is.
// For tell the type of object, we uses type-transforming. In this case, we tell the program this object type is "Double[]"
