Refactor the code

class ClassA
{
  public ClassA() { }

  public ClassA(int pValue) {  }
}

// client program
class Program
{
  static void Main(string[] args)
  {
    ClassA refA = new ClassA();
  }
}

Is there a way to modify ClassA so that you can you call the constructor with parameters, when the Main method is called, without creating any other new instances of the ClassA?

The this keyword is used to call other constructors, to initialize the class object. The following shows the implementation:

class ClassA
{
  public ClassA() : this(10)
  { }

  public ClassA(int pValue)
  {  }
}
