At first glance, the difference between dynamic and var may not be entirely obvious. With either, you do not have to tell the compiler explicitly what type of data you re working with the compiler ultimately ensures that the right thing happens. For example, whether using dynamic or var, the + operator has the same effect that it would have if you had used it with explicitly typed variables. So why do we need both The difference is timing: var does things much earlier. The C# compiler insists on being able to work out what type of data is in a var variable at compile time. But with dynamic, it works it out at runtime. This means there are some things you can do with dynamic that you cannot do with var. As Example 18-4 showed, you can use dynamic for the arguments of a function declaration, and also for its return type. But this would be illegal with var:

The one-time password system used to be implemented by giving users lists of passwords These lists were essentially small books full of passwords customized for users each time they would log in For example, the first time that the user logs in, she would use the first password on the list The next time she logs in, she would be instructed to use the second password on the list The system could also choose a random password number and expect the user to enter that number These lists, however, became cumbersome for users Most one-time password systems today are ones in which the user is given some device with a small amount of computing power that is used to compute passwords The device can be used as a source of passwords.

static var WillNotCompile(var a, var b) // Error { return a + b; }

The compiler has insufficient information to work out at compile time what the argument and return types are here. But with dynamic, that doesn t matter the compiler doesn t need to know at compile type what type of data we re using because it will generate code that works out what to do at runtime. Here s another thing that dynamic can do that var cannot:

dynamic differentTypes = "Text"; differentTypes = 42; differentTypes = new object();

The value in differentTypes changed from one line to the next. If we had used var, this would have been illegal a var variable s type is determined by the expression used to initialize it, so in this case, it would have been a string, meaning the second line would have failed to compile. So dynamic and var perfectly represent the distinction between dynamic and static: a dynamic variable s type (and consequently the behavior of any operations using that variable) is determined at runtime; a var variable s type is static it is determined at compile time and cannot change.

So the behavior is consistent with what we re used to with C#. The + operator continues to mean all the same things it can normally mean, it just picks the specific meaning at runtime it decides dynamically. The + operator is not the only language feature capable of dynamic operation. As you d expect, when using numeric types, all the mathematical operators work. In fact, most of the language elements you can use in a normal C# expression work as you d expect. However, not all operations make sense in all scenarios. For example, if you tried to add a COM object to a number, you d get an exception. (Specifically, a RuntimeBinderException, with a message complaining that the + operator cannot be applied to your chosen combination of types.) A COM object

The users, when they log into a system, take out the onetime password device, read off the password from that device, and enter it into the computer system All the passwords that are generated by this device are based off of some cryptographic algorithm There is typically some seed (initial value) that is used to generate an entire stream of many passwords over time That seed is also known by the server Therefore, given the current time and the seed, the server can check that the password the user is entering is correct The functionality provided in these one-time password devices are now integrated into PDAs, cell phones, and other mobile devices that users already carry One-time passwords end up being a very good system for ensuring password security.

such as one representing an Excel spreadsheet is a rather different sort of thing from a .NET object. This raises a question: what sorts of objects can we use with dynamic

We ve already seen one tool for dividing our code into manageable pieces: methods. A method is a piece of a program that encapsulates a particular behavior completely. It s worth understanding the benefits of methods, because the same principles apply to the classes and structs that are this chapter s main subject.

You will often see the term function used instead of method; they re related, but not identical. A function is a method that returns something. Some methods just do some work, and do not return any value. So in C#, all functions are methods, but not all methods are functions.
