New in C# 2.0: Anonymous methods: delegate expressions (C# Precisely section 12.20)
Advanced API’s often have methods that take delegates as arguments, for instance:
class IntList {
public IntList Filter(IntPredicate p);
…
}
delegate bool IntPredicate(int x);
The Filter method may return a list containing only those elements x for which p is true.
We can define a method Even that is true for even integers, make a delegate, and apply Filter to it:
static bool Even(int x) { return x%2 == 0; }
…
list.Filter(Even);
C# 2.0 allows us to define Filter’s delegate argument inline, as an anonymous method:
list.Filter(delegate(int x) { return x%2…
