C# (CSharp) FunctionalTricks Examples

Example #1

        public void OnlyLastResultReturned()
        {
            FunctionalTricks f      = new FunctionalTricks();
            Curry            adding = f.Add5;

            adding += f.Add10;
            //Delegates may have more than one method attached, but only the result of the last method is returned.
            Assert.Equal(15, adding(5));
        }
