constructors

class Class1
{
    static void Main(string[] args)
    {
        MyDerivedClass derived = new MyDerivedClass(3);
    }
}

public class MyBaseClass
{
    public MyBaseClass()
    {
        Console.WriteLine("MyBaseClass()");
    }

    public MyBaseClass(int i)
    {
        Console.WriteLine("MyBaseClass(int i)");
    }
}

public class MyDerivedClass : MyBaseClass
{
    public MyDerivedClass()
    {
        Console.WriteLine("MyDerivedClass() base(5) -> {0}");
    }

//    public MyDerivedClass(int i)
//    {
//        Console.WriteLine("MyDerivedClass(int i)");
//    }

    public MyDerivedClass(int i, int j)
    {
        Console.WriteLine("MyDerivedClass(int i,int j) -> {0},{1}",i,j);
    }

    public MyDerivedClass(int j) : base(i)
    {
        Console.WriteLine("MyDerivedClass(int j) : base(i) -> i={0} j={0}",i,j);
    }

} 

doesnt work bcoz he says base(i) doesnt exist . . .
