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
     }
 }
