Java acts as D here:

C# requires the new keyword:

A D version that does as you desire:
import std.stdio;
class SC {
string f_ = "SC";
@property string f() { return f_; }
void show() { writeln(this.f); }
}
class C : SC {
string f_ = "C";
@property override string f() { return f_; }
}
void main () {
auto c = new C();
writeln(c.classinfo.name);
auto sc = new SC();
writeln(sc.classinfo.name);
writeln(c.f); // "C"
c.show(); // "C"
}
