C# 如何使用信号器保存数据？

我想用信号器保存数据。比如说,

public void ReservationOpened(long contractId, string username)
{
    // Save the contractId somewhere, that we can access it later. Let's call it ListOfOpenedIds
    Clients.All.reservationOpened(contractId, username);
}

public void ReservationClosed(long contractId)
{
    // look in ListOfOpenIds for contractId, and then remove it.
    Clients.All.reservationClosed(contractId);
} 

我怎样才能做到这一点？我听说不建议使用signar使用Session。所以我想我不会使用Http.Current.Context.Session

至于数据库方法，我不喜欢每次打开/关闭都使用dbWrite/dbRead

---

有人能告诉我如何做到这一点吗？如果数据库方法是最好的方法，我应该在哪里初始化数据库连接？

您可以将此数据存储在静态变量中。它将具有全局作用域，并且不是每个用户唯一的，但如果使用字典，则可以根据连接id查找用户会话数据

我使用一个会话管理器单例类，有两个字典将连接id映射到会话数据，将用户名映射到会话数据。这允许我通过连接id识别连接用户，并在向特定用户发送消息时找到相关的连接id

会话数据类：

public class Player
{
    public Player()
    {
        ConnectionIDs = new List<string>();
    }
    public List<string> ConnectionIDs { get; set; }
    public string Name { get; set; }
    public string username { get; set; }
}

会话管理器类：

public class Lobby
{
    private Lobby()
    {
        playersByUsername = new Dictionary<string, Player>();
        playersByConnectionID = new Dictionary<string, Player>();
    }

    private static Lobby singleton;
    public static Lobby Get()
    {
        if (singleton == null)
            singleton = new Lobby();

        return singleton;
    }

    Dictionary<string, Player> playersByUsername;
    Dictionary<string, Player> playersByConnectionID;

    public Player GetPlayerByUsername(string username)
    {
        if (playersByUsername.ContainsKey(username))
            return playersByUsername[username];

        return null;
    }

    public Player GetPlayerByConnectionID(string connectionID)
    {
        if (playersByConnectionID.ContainsKey(connectionID))
            return playersByConnectionID[connectionID];

        return null;
    }

    public void NewPlayer(Player player)
    {
        playersByUsername.Add(player.username, player);
        foreach (string connectionID in player.ConnectionIDs)
            playersByConnectionID.Add(connectionID, player);
    }

    public void NewConnection(string username, string connectionID)
    {
        playersByConnectionID.Add(connectionID, playersByUsername[username]);
        playersByUsername[username].ConnectionIDs.Add(connectionID);
    }

}
