Getting to know anonymous methods

In the previous chapter, we already discussed how to declare a delegate using named methods. When using named methods, we've have to create a method first, give it a name, and then associate it with the delegate. To refresh our memory, a simple delegate declaration associated with a named method is provided as follows:

delegate void DelDelegate(int x); 
void DoSomething(int i) { /* Implementation */ } 
DelDelegate d = DoSomething; 

From the preceding code, we simply create a delegate data type named DelDelegate, and we also create a method named DoSomething. After we have a named method, we can associate the delegate with the method. Fortunately, anonymous methods were announced in C# 2.0 to ease the use of delegates. They provide us with a shortcut to create a simple and short method that will be used once. The syntax to declare an anonymous method is as follows:

delegate([parameters]) { implementation }
