Editor to share with you how the structure of C# is like, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

There are many similarities between a class and a structure: a structure can implement an interface and can have the same member type as a class. However, structures differ from classes in several important respects: structures are value types rather than reference types, and structures do not support inheritance. The value of the structure is stored on the stack or inline. Careful programmers can sometimes enhance performance by using structures wisely.

For example, defining Point as a structure rather than a class can save a lot of memory space at run time. The following program creates and initializes an array of 100 points. For Point, which is implemented as a class, there are 101 instance objects, because the array needs one, and each of its 100 elements needs one.

Class Point {public int x, y; public Point (int x, int y) {this.x = x; this.y = y;}} class Test {static void Main () {Point [] points = new Point [100]; for (int I = 0; I < 100; iTunes +) points [I] = new Point (I, iTuni);}}

If you change Point to be implemented as a C # structure, such as

Struct Point {public int x, y; public Point (int x, int y) {this.x = x; this.y = y;}}

Only one instance object (the object used for the array) appears. Point instances are allocated inline in the array. This optimization may be misused. Using structures instead of classes also makes the application run more slowly or takes up more memory, because passing an instance of the C# structure as a value parameter results in the creation of a copy of the structure.

The above is all the content of this article "what is the example of C# structure?" Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
