C# static class example
- Let's see the example of static class that contains static field and static method.
using System;
public static class MyMath
{
public static float PI=3.14f;
public static int cube(int n){return n*n*n;}
}
class TestMyMath{
public static void Main(string[] args)
{
Console.WriteLine("Value of PI is: "+MyMath.PI);
Console.WriteLine("Cube of 3 is: " + MyMath.cube(3));
}
}C# examples - Output :
Value of PI is: 3.14
Cube of 3 is: 27
