#1,119 – Scope of Iteration Variable Is Limited to Body of foreach

The iteration variable that is set to a new element during each pass of a foreach statement only has scope within the body of the foreach loop.  It may not be used or referenced outside of the loop.

            List<Dog> myDogs = new List<Dog>
                {
                    new Dog {Name = "Kirby", Age = 15},
                    new Dog {Name = "Ruby", Age = 2},
                    new Dog {Name = "Jack", Age = 17}
                };

            foreach (Dog d in myDogs)
            {
                Console.WriteLine(d);
                d.Age++;
            }

            // Compile Error: The name 'd' does not exist in the current context
            string someDog = d.Name;
