Algorithm
In C#, the static keyword is used to define members of a class that belong to the class itself rather than instances of the class. This means that you can access static members without creating an instance of the class.
Here are the main uses of the static keyword in C#:
Code Examples
#1 Static Variables in C# program
Code -
C# Programming
using System;
namespace StaticKeyword {
class Student {
// static variable
public static string department = "Computer Science";
}
class Program {
static void Main(string[] argos) {
// access static variable
Console.WriteLine("Department: " + Student.department);
Console.ReadLine();
}
}
}Output
#2 Static Variables Vs Instance Variables in C#
Code -
C# Programming
class Student {
// instance variable
public string studentName;
}
class Program {
static void Main(string[] args) {
Student s1 = new Student();
Student s2 = new Student();
}
}#3 Code Excample- Static Variable Vs. Instance Variable in C# Programming
Code -
C# Programming
using System;
namespace StaticKeyword {
class Student {
static public string schoolName = "DevsEnv School";
public string studentName;
}
class Program {
static void Main(string[] args) {
Student s1 = new Student();
s1.studentName = "Akash";
// calls instance variable
Console.WriteLine("Name: " + s1.studentName);
// calls static variable
Console.WriteLine("School: " + Student.schoolName);
Student s2 = new Student();
s2.studentName = "Azad";
// calls instance variable
Console.WriteLine("Name: " + s2.studentName);
// calls static variable
Console.WriteLine("School: " + Student.schoolName);
Console.ReadLine();
}
}
}Output
School: DevsEnv School
Name: Azad,br> School: DevsEnv School
#4 Static Methods in C# Program
Code -
C# Programming
class Test {
public static void display() {....}
}
class Program {
static void Main(string[] args) {
Test.display();
}
}#5 Static and Non-static Methods in C# Programming
Code -
C# Programming
using System;
namespace StaticKeyword {
class Test {
public void display1() {
Console.WriteLine("Non static method");
}
public static void display2() {
Console.WriteLine("Static method");
}
}
class Program {
static void Main(string[] args) {
Test t1 = new Test();
t1.display1();
Test.display2();
Console.ReadLine();
}
}
}Output
Static method
#6 Static Class in C# Programming
Code -
C# Programming
using System;
namespace StaticKeyword {
static class Test {
static int a = 5;
static void display() {
Console.WriteLine("Static method");
}
static void Main(string[] args) {
// creating object of Test
Test t1 = new Test();
Console.WriteLine(a);
display();
}
}
}#7 Access static Members within the Class in C# programming
Code -
C# Programming
using System;
namespace StaticKeyword {
class Test {
static int age = 25;
public static void display() {
Console.WriteLine("Static method");
}
static void Main(string[] args) {
Console.WriteLine(age);
display();
Console.ReadLine();
}
}
}Output
Static method
