C# Static Class with Examples

In c#, a static class can be created by using static modifier and the static class can contain only static members.


Generally, the static class is same as non-static class, but only difference is the static class cannot be instantiated. Suppose if we apply static modifier to a class, then we should not use the new keyword to create a variable of the class type.


Another difference is the static class will contain only static members, but the non-static class can contain both static and non-static members.

C# Static Class Syntax

In c#, we can create a static class by applying static keyword to the class like as shown below.


static class sample


     //static data members

    //static methods


If you observe above syntax, to create a static class called “sample”, we applied static keyword to the class type. The methods and data members which we are going to implement in sample class must be a static.


In c#, we can access a members of static class directly with the class name. For example, we have a static class called “User” with a method “Details()” that we can access like User.Details().

C# Static Class Example

Following is the example of defining a static class to access data members and member functions without creating an instance of class in c# programming language.


using System;


namespace Tutlane


    static class User


        // Static Variables

        public static string name;

        public static string location;

        public static int age;

        // Static Method

        public static void Details()


            Console.WriteLine("Static Method");



    class Program


        static void Main(string[] args)


            User.name = "Suresh Dasari";

            User.location = "Hyderabad";

            User.age = 32;

            Console.WriteLine("Name: {0}", User.name);

            Console.WriteLine("Location: {0}", User.location);

            Console.WriteLine("Age: {0}", User.age);


            Console.WriteLine("\nPress Enter Key to Exit..");





If you observe above example, we are accessing static class members and functions directly with the class name because we cannot instantiate the static class.


When we execute above c# program, we will get the result like ass shown below.

This is how we can create a static class and use it in our c# applications based on our requirements.

C# Static Class Features

Following are the main features of static class in c# programming language.


  • The static class in c# will contain only static members.
  • In c#, the static classes cannot be instantiated.
  • C# static classes are sealed, therefore it cannot be inherited.
  • The static classes in c# will not contain instance constructors.

As discussed in previous article static keyword in c#, we can use static members in non-static classes such as normal classes. For normal classes we can create an instance of class using new keyword to access non-static members and functions but it cannot access the static members and functions.


To know more about it, check this article static keyword in c# with examples.


The advantage of using static classes in c# applications will make sure that instance of classes cannot be created.
