C# .Net Deserialization $type Not Working -


i'm trying deserialize json using $type property. however, error stating "type specified in json not resolved. i'm not sure i'm doing wrong. appreciated.

my json 

{ movies: [     {         $type:"rtmoviepagewithslides",         title:"reservoir dogs",         slides:[             {$type:"rtcharacterpage", title:"mr. orange",       img:""},             {$type:"rtcharacterpage", title:"mr. blonde",       img:""},             {$type:"rtcharacterpage", title:"mr. white",        img:""},             {$type:"rtcharacterpage", title:"mr. pink",         img:""},             {$type:"rtcharacterpage", title:"nice guy eddie",   img:""},         ]     }     {         $type:"rtmoviepagewithsubpages",         title:"jackie brown",         pages:[             {$type:"rtactorpage", title:"pam gier",             other_movies:[]},             {$type:"rtactorpage", title:"samuel l. jackson",    other_movies:[]},             {$type:"rtactorpage", title:"robert forester",      other_movies:[]}         ]     } ] }

my classes

using system.collections; using system.collections.generic;  public class rtmoviedata {     public list<rtmoviepage> movies;     }  public class rtmoviepage {     public string title; }  public class rtmoviepagewithslides : rtmoviepage{     public list<rtmoviepage> slides = new list<rtslidepagedata>{}; }  public class rtmoviepagewithsubpages : rtmoviepage{     public list<rtmoviepage> pages = new list<rtpagedata>{}; }  public class rtcharacterpage : rtmoviepage {     public string img; }  public class rtactorpage : rtmoviepage {     public  list<string>other_movies; }

deserialization code

var settings = new jsonserializersettings();     settings.typenamehandling = typenamehandling.auto;      rtmoviedata data = jsonconvert.deserializeobject<rtmoviedata>(jsonstring, settings);

@programmer mentions post "deserialization of json using minijson" in unity c#" duplicate post. however, 2 posts not related @ all. other post describes user using different json deserializer , was having problem getting array deserialize. issue specific using $type property deserializer instantiate subclasses stated in title of post.

solution: in json needed add "assembly-csharp" value of $type property.

$type:"rtmoviepagewithslides, assembly-csharp"

and 

$type:"rtcharacterpage, assembly-csharp"

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
