Question 3

How can you change the size of an array in C#?

Accepted Answer

You can change the size of an array associated with an identifier, if necessary. For example, if you declare int [] array; , you can assign five elements later with array = new int [5]; ; later in the program, you might alter the array size to 100 with array = new int [100]; . Still later, you could alter it again to be either larger or smaller. This feature is not allowed in most other programming languages. If you resize an array in this manner, the same identifier refers to a new array in memory and all the values are set to 0.
