vb.net - Is it possible to create an immutable property on a domain model? -


we have a number of logical domain objects reside in same physical database table workstep. simple sample of metadata in sql table id |name| type, such type fk table defines types possible. however, once selected database each row might represent different domain model, different business rules must applied. business rule working right once created, worksteptype property 1 of these objects can never change. so, call cause this change bad thing.

so, possible make object can constructed via add-ons automapper, , dapper, can have property set once. , never changed? also, types can not cast each other.

i haven't tried much, i'm not sure possible without hacky code

dapper maps private properties (or private setters/mutators).

public class workstep {     public worksteptype worksteptype { get; private set;} }

if need resulting domain object specific type, make above class simple factory generates type looking for.

public class workstepfactory     {         public worksteptype worksteptype { get; private set;}  public t createworkstep<t>() t : workstepbase{...}      }

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
