如何查找对象在列表中的位置？

Question

我有一个“玩家”列表，我想知道我的玩家是否

players[0]

或

players[1]

或其他任何东西。我该怎么做？

Answer 1

linq命令的使用

List<Player> players = new List<Player>();

players.Add(new Player() { Id = "1", Name = "angle" });
players.Add(new Player() { Id = "2", Name = "cristin" });
players.Add(new Player() { Id = "2", Name = "robert" });

var finded= players.Where(x => x.Name == "cristin").FirstOrDefault();

public class Player
{
   public string Id { get; set; }
   public string Name { get; set; }
}

Answer 2

这个怎么样：

public int GetIndex(List<PlayerClass> playersList, PlayerClass player)
{
    return playersList.FindIndex(a => a == player);
}

如果玩家不在列表中，它应该return-1。

Answer 3

您可以使用 List<T>.IndexOf 方法。
