C# Structs - c# - c# tutorial - c# net
What is struct C# ?
- In C#, classes and structs are blueprints that are used to create instance of a class.
- Structs are used for lightweight objects such as Color, Rectangle, Point etc.
- Unlike class, structs in C# are value type than reference type.
- It is useful if you have data that is not intended to be modified after creation of struct.

C# Struct Example
- Let's see a simple example of struct Rectangle which has two data members width and height.
using System;
public struct Rectangle
{
public int width, height;
}
public class TestStructs
{
public static void Main()
{
Rectangle r = new Rectangle();
r.width = 4;
r.height = 5;
Console.WriteLine("Area of Rectangle is: " + (r.width * r.height));
}

Area of Rectangle is: 20C# Struct Example: Using Constructor and Method
- Let's see another example of struct where we are using constructor to initialize data and method to calculate area of rectangle.
using System;
public struct Rectangle
{
public int width, height;
public Rectangle(int w, int h)
{
width = w;
height = h;
}
public void areaOfRectangle() {
Console.WriteLine("Area of Rectangle is: "+(width*height)); }
}
public class TestStructs
{
public static void Main()
{
Rectangle r = new Rectangle(5, 6);
r.areaOfRectangle();
}
}C# examples - Output :
Area of Rectangle is: 30- Note: Struct doesn't support inheritance. But it can implement interfaces.
