Class Methods

Just like structs, classes can also have methods. The syntax for creating and calling methods is also very similar:

For example, we can create a class called Rectangle with width and height attributes and a method called area, which calculates the area of the rectangle object based on the width and height values:

index.cs

index.cs

copy
1234567
class className { // ... other class code public returnType methodName(datatype param1, datatype param2, ...) { // code } }
index.cs

index.cs

copy
123456789101112131415161718192021222324252627
using System; public class ConsoleApp { class Rectangle { public double width; public double height; public double area() { return width * height; } } public static void Main(string[] args) { Rectangle r1 = new Rectangle(); r1.width = 10; r1.height = 20; Rectangle r2 = new Rectangle(); r2.width = 14.7; r2.height= 17.9; Console.WriteLine($"Area of R1 is {r1.area()}"); Console.WriteLine($"Area of R2 is {r2.area()}"); } }
