c# - Best way to provide params to a state transition in a FSM -

i'm in situation 1 of states in fsm needs information outside world job. information needs provided when transition requested. what's best way accomplish this? @ time i'm using fsm class blackboard share inforamtion between states.

one dirty solution have information cached in fsm , fill before requesting transition , let state have fsm black board. don't it.

my language c#

cheers.

to show meant passing delegate:

class mystatemachine {   private readonly func<string> askforname;    public mystatemachine(func<string> askforname)   {     this.askforname = askforname;   }    // ...    void statetransitionforactionx()   {     var name = askforname();      // ...   } }  public mystatemachine createmachine() {   return new mystatemachine    (      () =>       {        console.writeline("please, enter name: ");        return console.readline();      }    ); } 

of course, can used data request whatsoever - using console seemed simple way illustrate idea :) closures in particular can pretty powerful.
