Calling Base Constructor in Derived Class Constructor C#

I have a class A as below.

Class A
     public A(string str)
        //Does Something

Now I need to extend this class to B class. I am not supposed to touch A class.

class B : A
    public B()

Now I need to pass string to A constructor. but the string will be computed through some logic and it has to be passed to base class A.

Usually we can do something like

 public B() : base("c#") {}

but this is only applicable for some standard values. but i need to form the string and call the base constructor.

how to achieve this ?
