When to use Anonymous delegates

When to use Anonymous delegates

Best needs: predicates / comparer

Hi

Ever wondered why anonymous delegates were created when we already had proper delegates?

In normal delegate, we write as follows

Public delegate MyDelegate (string s);

Public void MyFunction(string s) { Console.Write(s); }

Public static void main() {

MyDelegate del = new MyDelegate(MyFunction);

del("Nitin");

}

In Anonymous delegates, we write

Public static void main() {

MyDelegate del = delegate(string s) { Console.Write(s); }

del("Nitin");

}

Basically this is same as

String s = "Nitin"; // this happens in normal delegate

myFunction(s);

myFunction("Nitin"); // this happens in anonymous delegate

Now the difference

If we don't need to use the function outside of the delegate scope, we can safely use anonymous delegate and remove the explicit function. If we need the function directly also, then we need to declare the function and use either anonymous or normal delegate.
