I read through this explanation of lambdas by @mk. and it has the following example:
Func<int, Func<int, int>> adder = (int x) => (int y) => x + y; // `int` declarations optional Func<int, int> add5 = adder(5); var add6 = adder(6); // Using implicit typing Debug.Assert(add5(1) == 6); Debug.Assert(add6(-1) == 5); // Closure example int yEnclosed = 1; Func<int, int> addWithClosure = (x) => x + yEnclosed; Debug.Assert(addWithClosure(2) == 3); I've used lambdas in C# for years and yet I do not understand what is going on here. Obviously this adds an instance variable, but what in the declaration is defining all this? Is x or y the instance variable? And what's with the Closure example at the bottom?
