Here we used a lambda expression to provide a delegate that takes a Document parameter called doc, and returns a string. In this case, it is just a constant string. Later, we ll do some work to emit a more useful message. Take a moment to notice again how compact the lambda syntax is, and how the compiler infers all those parameter types for us. Remember how much code we had to write to do this sort of thing back in the world of abstract base classes Compile and run, and we see the following output:

That s an example of a delegate for a function that returns something other than void or a bool. As you might have already guessed, the .NET Framework provides us with a generic type so that we don t have to declare those delegates by hand, either.

The .NET Framework exposes a generic class called Func<T, TResult>, which you can read as Func-of T and TResult. As with Predicate<T> and Action<T> the first type parameter determines the type of the first parameter of the function referenced by the delegate. Unlike Predicate<T> or Action<T> we also get to specify the type of the return value, using the last type parameter: TResult.

Class members can be associated with an instance or with the class. By default, members are associated with an instance. You can think of each instance of a class as having its own copy of each class member. These members are called instance members. Changes to the value of one instance field do not affect the values of the members in any other instance. So far, the fields and methods you ve looked at have all been instance fields and instance methods. For example, the following code declares a class D with a single integer field Mem1. Main creates two instances of the class. Each instance has its own copy of field Mem1. Changing the value of one instance s copy of the field does not affect the values of the other instances copies. Figure 6-2 shows the two instances of class D. class D { public int Mem1; } class Program { static void Main() { D d1 = new D(); D d2 = new D(); d1.Mem1 = 10; d2.Mem1 = 28; Console.WriteLine("d1 = {0}, d2 = {1}", d1.Mem1, d2.Mem1); } } This code produces the following output:

Just like Action<T>, there is a whole family of Func<> types which take one, two, three, and more parameters. Before .NET 4, Func<> went up to four parameters, but now goes all the way up to 16.

So we could replace our custom delegate type with a Func<>. We can delete the delegate declaration:

delegate string LogTextProvider(Document doc);

and update the property:

Besides instance fields, classes can also have static fields. A static field is shared by all the instances of the class. With a static field, all the instances access the same memory location. If the value of the memory location is changed by one instance, the change is visible to all the instances. The static modifier is used to declare a field static, as follows: class D { int Mem1; static int Mem2; Keyword }

public Func<Document,string> LogTextProvider { get; set; }

var customer = { firstName: 'John', lastName: 'Doe' };

We can build and run without any changes to our client code because the new property declaration still expects a delegate for a function with the same signature. And we still get a bit of log text:

Processing document 1 The processing will not succeed. Some text for the log... Processing document 2 Document traduit. Some text for the log... Spellchecked document. Some text for the log... Repaginated document.

The NET Framework class library is big To make it easier to find your way around the many services it offers, the library is split into namespaces For example, the SystemIO namespace offers I/O (Input/Output) services such as working with files on disk, while SystemDataSqlClient is for connecting to a SQL Server database A namespace contains types A type typically represents either a kind of information or a kind of object For example, there are types that provide the core forms of information used in all programs, such as SystemString which represents text, or the various numeric types such as SystemDouble or SystemInt32 Some types are more complex for example, the SystemNetHttpWebRequest class represents an HTTP request to be sent to a web server.

For example, the code in Figure 6-3 declares class D with static field Mem2 and instance field Mem1. Main defines two instances of class D. Because Mem2 is static, both instances of class D share a single Mem2 field. If Mem2 is changed in one instance, it is changed in the other as well. Member Mem1 is not declared static, so each instance has its own copy.
