namespace kompiler
{
    class fda
    {
        public enum state
        {
            /* 0*/
            INIT = 0, ACCEPTCHAR, ACCEPTNUM, ETC
        };

        /* Doesn't compile; No overload for method 'Add' takes '1' arguments */
        Dictionary<char, Dictionary<state, state>> students = new Dictionary<char, Dictionary<state, state>>()
            {
                { 'l', new Dictionary <state, state>  ()  {
                             state.INIT, state.INIT }
                },
                { 'd', new Dictionary<state, state>(){
                             state.INIT, state.INIT }
                },
                { '"', new Dictionary<state, state>(){
                             state.INIT, state.INIT }
                }
            };
         
    }
}

There needs to be an extra set of {} around each of the { state, state }

Now the Dictionary declaration looks like this

Dictionary<char, Dictionary<state, state>> students = new Dictionary<char, Dictionary<state, state>>()
{
{ 'l', new Dictionary <state, state> () {
{state.INIT, state.INIT}
}
},
{ 'd', new Dictionary<state, state>(){
{ state.INIT, state.INIT }
}
},
{ '"', new Dictionary<state, state>(){
{ state.INIT, state.INIT }
}
}
};
