Like this…?

public class DerivedFromDerived (int i) : base (int j) : base (int k) {

The derived class already calls the base constructor in its constructor - you have to pass all of the parameters to the derived constructor and pass the appropriate ones up the chain…

public class ClassA
{
    public ClassA(int k)
    {
        // do something with k
    }
}

public class ClassB : ClassA
{
    public ClassB(int j, int k) : base(k)
    {
        // do something with j
    }
}

public class ClassC : ClassB
{
    public ClassC(int i, int j, int k) : base(j, k)
    {
        // do something with i
    }
}
