Analysis of examples of C # Array Operation
This article mainly explains the "example Analysis of C # Array Operation". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought slowly and deeply. Let's study and learn "C # array operation example analysis"!
An array is a collection of objects of the same type. Because arrays can be of almost any length, you can use arrays to store thousands or even millions of objects, but you must determine the size of the array when you create it. Each item in the array is accessed by index, which is a number indicating where or where the object is stored in the array. Arrays can be used to store both reference types and value types.
