Solution Review: Override a Method in the Derived Class

// Base Class
class Product {
  // Private Data Members
  private string _className;
  
  public Product() { // Default Constructor
  	this._className = "Product";
  }
  // Getter Function
  public virtual string GetName() {
    return this._className;
  }
  
}
// Derived Class
class XProduct : Product { 
  
  private string _className;
  
  public XProduct(string className) { // Default Constructor
    this._className = className;
  }
  
  // Overriden Method
  public override string GetName() { 
    return base.GetName() + ", " +this._className;
  }
  
}
class Demo {
  
 public static void Main(string[] args) {
   
   Product beverage = new XProduct("Beverage");
   Console.WriteLine(beverage.GetName());
    
 }
}
