Question about inheritance

[Du Dang]

class Base
{
public Base (string str)
{
Console.WriteLine(str);
}
}

class Derived : Base
{
public Derived (int i)
{
// do some thing here based on "i" to generate a
string
base ("some string"); <- this does work
}
}

==================

// i know something like this would work .. but this is not what i need
public Derived (string msg) : base (msg) {
}

thanks for any suggestion

The very first statement in the body of a constructor is always the call to
the base class.
There can not be any other statements before a base(foo,...) call.

To work around this limitation, create a separate method that does something
(in your case, Console.WriteLine(str); ) and call this method from your base
and derived constructors.
