#964 – Declaring a Variable within a Block of Statements

When you declare a block of statements in your code, you can declare variables within that block that will have a scope that is local to the block.  This is, the variable will be visible only to other code within the block.

This is most often done within a function:

        static void DoSomething()
        {
            // Variable local to this function
            string name = "Bob";

            Console.WriteLine(name);
        }

You can, however, declare local variables within any block of statements.

            if (DateTime.Now.DayOfWeek == DayOfWeek.Wednesday)
            {
                string bestFood = "Pizza";
                Console.WriteLine(bestFood);
            }

            // Can't access bestFood variable out here
