A static class is a class that contains only static members and cannot be instantiated. You declare a class as static using the static keyword.

A static class:

Example :

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
Employee e1 = new Employee("keshav", 23);
Employee e2 = new Employee("Raj", 24);
EmployeeMethods.SpeakALot(e1);
Console.WriteLine(EmployeeMethods.MarriedName(e1,e2));
Console.ReadLine();
}
}

public static class EmployeeMethods
{
private static int NumSpeak = 5;

public static void SpeakALot(Employee d)
{
for (int i = 1; i <= NumSpeak; i++)
{
d.EmployeeSpeak();
}
}

public static string MarriedName(Employee d1, Employee d2)
{
return d1.Name + d2.Name;
}
}

public partial class Employee
{
public string Name { get; set; }
public int Age { get; set; }
public Employee(string name, int age)
{
Name = name;
Age = age;
}

public void EmployeeSpeak()
{
Console.WriteLine("Hello");
}
}
}
