C# Web Api公开特定属性而不是外键

我不熟悉C#和实体框架，有以下问题

我有一个球员和一个团队模型：

public class Player
{
    public int ID { get; set; }

    public string FirstName { get; set; }
    public string LastName { get; set; }
    public int TeamID { get; set; }
}

public class Team
{
    public int ID { get; set; }

    public string Name { get; set; }

    public virtual ICollection<Player> Players { get; set; }
}

但是我想要

{
ID: 7
FirstName: "Sidney"
LastName: "Crosby"
TeamID: Denver Broncos
}

Web Api控制器看起来像：

    public async Task<IHttpActionResult> GetPlayer(int id)
    {
        Player player = await db.Players.FindAsync(id);
        if (player == null)
        {
            return NotFound();
        }
        return Ok(player);
    }

public异步任务GetPlayer（int-id）
{
Player-Player=wait db.Players.FindAsync（id）；
if（player==null）
{
返回NotFound（）；
}
返回Ok（播放器）；
}

首先将您的玩家等级更改为引用父队，而不仅仅是ID：

    public class Player
    {
        public int ID { get; set; }

        public string FirstName { get; set; }
        public string LastName { get; set; }
        public virtual Team Team { get; set; }
    }

然后创建一个DTO对象，以在所需的结构中公开所需的属性：

    public class PlayerDto
    {
        public PlayerDto(Player player)
        {
            FirstName = player.FirstName;
            LastName = player.LastName;
            TeamName = player.Team.Name;
        }

        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string TeamName { get; set; }
    }

通过创建仅包含要返回的类型的属性的DTO。

    public class PlayerDto
    {
        public PlayerDto(Player player)
        {
            FirstName = player.FirstName;
            LastName = player.LastName;
            TeamName = player.Team.Name;
        }

        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string TeamName { get; set; }
    }
