Question Sort a list based on another List Id

Hello everyone..

I have one Class having UserId.

Code (CSharp):

1.  [Serializable]
2. public class Player
3. {
4.      public string flag;
5.      public string userId;
6.      public string userName;
7.      public int coin;
8. }

I have another class with some different Property:

Code (CSharp):

1. public class Player_Game
2. {
3.      public string playerName;
4.      public string userId;
5.      public bool isUserPlayer;
6. }

I have collection of Player_Game and Player as well:

Code (CSharp):

1.  public List<Player_Game> players;
2. public List<Player> players_JSON;

I want to order players list based on userId of players_JSON List.

I am not able to properly cast :

Code (CSharp):

1. players = players.OrderBy(x => players_JSON.FindIndex(x.userId)).ToList();

i am getting error like x.userId can not convert from string to Player.

 

Code (CSharp):

1. players = players.OrderBy(x => players_JSON.FindIndex(y => y.userId == x.userId)).ToList();

 

Thank you so much. Its working
