我如何设置 internal user_id User.user_id . 我用breakpoint检查了一下,当 user.user_id

等级

public class Project
{
    public int id {get; set;}
    public string name {get; set;}

    // user_id is null while user.user_id has value as sent in request body
    internal int? user_id {get; set;}

    public User user {get; set;}

    public Project()
    {
        user_id = user?.user_id;
    }
}

public class User
{
    public int user_id {get; set;}
    public int user_name {get; set;}
}

[HttpPost]
public IActionResult Create([FromBody] Project project)
{
    return Ok(project);
}

更改模型如下:

public class Project
{
    public int id { get; set; }
    public string name { get; set; }

    internal int? user_id { get; set; }
    private User _user;
    public User user
    {
        get { return _user; }
        set
        {
            _user = value;

            // Assign user_id 
            user_id = value.user_id;
        }
    }
    //public User user { get; set; }

}

看起来您正在使用内部属性 user_id 只是为了阅读 用户id 的 user 用户id 的物体穿过它,就像-

public class Project
{
    public int id { get; set; }
    public string name { get; set; }
    internal int? user_id { get { return user.user_id; } }

    public User user { get; set; }
}
