It should be fairly apparent that a value type also needs to be pretty lightweight, because of all that copying going on Every time you pass it into a function, or assign it to a variable, a copy is made And copies are generally the enemy of good performance If your value type consists of more than two or three of the built-in types, it may be getting too big These constraints mean it is very rare that you will actually want to declare a value type yourself A lot of the obviously useful ones you might want are already defined in the NET Framework class libraries (things like 2D points, times, and dates) Custom value types are so rare that it was hard to come up with a useful example for this book that wasn t already provided in the class libraries.

(If you were wondering why our example application represents aircraft positions in such an idiosyncratic fashion, this is the reason) But that doesn t mean you should never, ever declare a value type Value types can have performance benefits when used in arrays (although as with most performance issues, this is not entirely clear-cut), and the immutability and copy semantics can make them safer when passing them in to functions you won t normally introduce side effects by working with a value type because you end up using a copy, rather than modifying shared data that other code might be relying on Our polar 3D point seems to comply with the requirements Any given point is just that: a specific point in 3D space a good candidate for immutability.

(We might want to move a plane to a different point, but we can t change what a particular point means) It is also no more than three doubles in size, which is small enough for copy semantics Example 3-28 shows our declaration of this type, which we can add to our project (As with enum, Visual Studio doesn t offer a template for value types Again, we can use the Class template, replacing the class with the code we want).

In the case that the user asks to create a key, the program creates a new file using a FileOutputStream object, and writes the key returned by the KeyGenerator s generateKey() method to the file The KeyGenerator class in Java should be used to construct cryptographically random keys that are not weak (see Section 142 for more information about weak keys) If the user requests encryption or decryption, the main program simply calls the encrypt() or decrypt() method, respectively, after initializing the AESEncrypter object with the key read from the key file (If the user did not specify a valid operation, a usage error is printed) From the preceding example, you can see how it s possible to practically implement a flexible encryption tool in just a few lines of code With just this small program, you can encrypt and decrypt any file.

struct PolarPoint3D { public PolarPoint3D(double distance, double angle, double altitude) { Distance = distance; Angle = angle; Altitude = altitude; } public double Distance { get; private set; } public double Angle { get; private set;

} public double Altitude { get; private set; }

}

If you think that it looks just like a class declaration, but using the struct keyword instead of class, you d be right these two kinds of types are very similar. However, if we try to compile it, we get an error on the first line of the constructor:

However, AESEncrypter does not provide integrity protection for the encrypted file, and in the real world you would add on a message authentication code (MAC) and use a key derivation function to get a different MAC and encryption key Aside from the limitation of not automatically providing integrity protection, the AESEncrypter class is written such that it can be used in other programs to encrypt and decrypt not only files, but also any data that can be transferred over a stream, including data that is exchanged between clients and servers over network sockets As you can imagine, one major challenge is securely distributing the key file to the client and server In s 13 and 14, we discuss asymmetric cryptography and key exchange, which helps address the key distribution problem In this chapter, we complete our discussion of symmetric cryptography with an introduction to stream ciphers..

So, although the basic syntax of a struct looks just like a class there are important differences Remember that when you allocate an instance of a particular type, it is always initialized to some default value With classes, all fields are initialized to zero (or the nearest equivalent value) But things work slightly differently with value types we need to do slightly more work Anytime we write a struct, C# automatically generates a default, parameterless constructor that initializes all of our storage to zero, so if we don t want to write any custom constructors, we won t have any problems (Unlike with a class, we aren t allowed to replace the default constructor We can define extra constructors, but the default constructor is always present and we re not allowed to write our own see the sidebar on the next page for details.
