write classes with virtual methods which is derived from your abstract base class SomeThingWriter.

then every class which are derived from base class should implement a function like writeSomething or whatever you want.

abstract class MyBaseClass
{
     public abstract void writeSomething();
}

class DerivedClass1 : MyBaseClass
{
    public override void writeSomething()
    {
        Writeln("something else here  1");
    }
}

class DerivedClass2 : MyBaseClass
{
    public override void writeSomething()
    {
        Writeln("something else here  2");
    }
}

than just call like

MyBaseClass c = new DeriveClass1();
c.writeSomething();
c = new DerivedClass2();
c.writeSomething();
