#1,126 – Rewriting a Loop to Avoid continue Statement

The continue statement allows jumping to end of the body of a loop, skipping the rest of the code within the loop.  Either the next iteration of the loop executes, or the code following the loop statement executes.

            List<Dog> myDogs = new List<Dog>
            {
                new Dog {Name = "Kirby", Age = 5},
                new Dog {Name = "Jack", Age = 17},
                new Dog {Name = "Ruby", Age = 2}
            };

            foreach (Dog d in myDogs)
            {
                if (d.Age > 15)
                    continue;

                Console.WriteLine("{0} doing a trick", d.Name);
                d.DoATrick();
            }

In most cases, you can rewrite the body of a loop and avoid using a continue statement by using an if statement.  The end result is generally more readable.

            foreach (Dog d in myDogs)
            {
                if (d.Age <= 15)
                {
                    Console.WriteLine("{0} doing a trick", d.Name);
                    d.DoATrick();
                }
            }
