#11 Static Class, Methods, Constructor, Fields

When you define a class, method constructor, or field as static it means that a thing will only have one instance of it and it can’t be instantiated. I.e you are taking away the ability to create or access it using an object.


  • Static classes can’t be instantiated.
  • If a class is declared as static then all its members must also be declared as static.
  • Static classes are sealed and hence can’t be inherited.
  • A static class remains in memory till the lifetime of the application.
using System;
public static class Staticclass
    public static int Value { get; set; }

    public static int getValue()
        return Value;

public class nonstaticclass
    public int Value { get; set; }

    public static void getValue()
        Console.WriteLine("I cant access value property");

class Program
    static void Main(string[] args)
        //below object cretion will not work
        //Staticclass obj = new Staticclass();
        Staticclass.Value =10;
        nonstaticclass obj = new nonstaticclass();
        obj.Value =10;
        //obj.getValue(); this will not work
