SportsCar sc = new SportsCar(100);
SportsCar sc2 = sc;
sc.SpeedUp(); // Method adds 20
Console.WriteLine(sc.Speed); // 120
Console.WriteLine(sc2.Speed); // 120
// In this code, sc and sc2 refer to the same object. The last two lines will print the same value to the console.In C#, classes and interfaces are reference types. Variables of reference types store references to their data (objects) in memory, and they do not contain the data itself.
An object of type Object, string, or dynamic is also a reference type.
