Postman 'POST' request sucess but Angular 5 'Post' not working

I am trying to insert a data object via web API to the database. when I using the Postmen, POST request is the success. but in angular 5 app post request indicates 500 Internal saver error. here is my source code.

player.service.ts

@Injectable()

export class PlayerService {





  private _postPlayer = 'http://192.168.8.101/api/Values/insertData';

  constructor(private _http: HttpClient) { }

  httpOptions = {

    headers: new HttpHeaders({

      'Content-Type': 'application/json',



    })

  };



  // save the new player



  save(palyer: Player): Observable<Player> {



    console.log(palyer.playingRole);

    return this._http.post<Player>(this._postPlayer, palyer, this.httpOptions)

  }

}

here are my Components

export class AddplayerComponent implements OnInit {

 player: Player = new Player(); 

 playerAdd: FormGroup;

 players: Player;



  constructor(private plService: PlayerService) { }



  ngOnInit() {

    this.playerAdd = new FormGroup(

     {

      firstName: new FormControl(),

      lastName: new FormControl(),

      nickName: new FormControl(),

      birthday: new FormControl(),

      playingRole: new FormControl(),

      battingStyle: new FormControl(),

      bowllingStyle: new FormControl(),

      mobileNumber: new FormControl(),

      email: new FormControl() 





     }



    );





  }



  save() {

    console.log(this.playerAdd.value);

   this.player = this.playerAdd.value;

   this.plService.save(this.player)

   .subscribe();

  }



}

Here are my ASP.NET WebApi Post

[HttpPost]

public void insertData([FormBody] Player Ob){

  // to connect EF6 context



}

Get request is working fine. but Post request is not working.

You need to stringify your object:

  return this._http.post<Player>(this._postPlayer, JSON.stringify(palyer), this.httpOptions)

And added the microsoft.aspnet.webapi.cors package to the API.
