Static class in C#
The C# static class cannot be instantiated and can only have only static members. The static class in C# is sealed and cannot contain instance constructors.
The following is an example with static class and static members −
Example
using System; public static class Demo { public static float PI = 3.14f; public static int calc(int n){return n*n;} } class Program { public static void Main(string[] args) { Console.WriteLine("PI: "+Demo.PI); Console.WriteLine("Square: " + Demo.calc(3)); } }
Output
PI: 3.14 Square: 9
Above, the static class is −
public static class Demo { public static float PI = 3.14f; public static int calc(int n){return n*n;} }
Above we have the following static members −
public static float PI = 3.14f; public static int calc(int n){return n*n;}
