How can I call a base class's parameterized constructor from a derived class if the derived class has no parameterized constructor?

Question

I have a base class with two constructors: a default constructor and a parameterized constructor. Another class inherits from that base class and it only has a default const

Here you go:

// Parent class
class Parent
{
    public Parent()
        {
        // Paremeterless constructor
        }

        public Parent(string a, int b)
        {
        // Paremterised constructor
        }       
}


// Child class       
class Child : Parent
{
    public Child()
                :base("hi", 10)
        {
        // Parameterized constructor of the base class is invoked   
        }
}
