Asp.Net Mvc WebSocket - 客户端的自定义参数

Question

我的 WebSocket 结构如下。

public HttpResponseMessage Get(int id, string kod)
{
    if (HttpContext.Current.IsWebSocketRequest)
    {
        HttpContext.Current.AcceptWebSocketRequest(new SocketHandler(id, kod));      
        return Request.CreateResponse(HttpStatusCode.SwitchingProtocols);
    }
    else
    {
        return Request.CreateResponse(HttpStatusCode.BadRequest);
    }
}

class SocketHandler : WebSocketHandler
{
    DnaEntities db = new DnaEntities();

    private static WebSocketCollection Clients = new WebSocketCollection();
    private Yonetim_Kullanici Kullanici;

    public SocketHandler(int KullaniciId, string OturumKontrolKod)
    {
        var sorgu = db.Yonetim_Kullanici.Where(k => k.Id == KullaniciId && k.OturumKontrolKod == OturumKontrolKod && k.Durum == 1);
        if (sorgu.Count() == 1)
        {
            Kullanici = sorgu.FirstOrDefault();
        }
    }

    public override void OnOpen()
    {
        if (Kullanici != null)
        {
            Clients.Add(this);
        }
        base.OnOpen();
    }
    public override void OnClose()
    {
        Clients.Remove(this);
        base.OnClose();
    }

    public override void OnMessage(string data)
    {
        foreach (var item in Clients)
        {
            var data = item.Kullanici
            //item.Send();
        }
    }

如下，发给大家

Clients.Broadcast(message);

但是，当我要一一发送时：

foreach (var item in Clients)
{
    var UserModel = item.Kullanici;
}

错误信息：

'WebSocketHandler' does not contain a definition for 'Kullanici' and no extension method 'Kullanici' accepting a first argument of type 'WebSocketHandler' could be found.

item.Kullanici => 正如您在 picture

中看到的

我认为您应该能够首先将其转换为继承的 class，例如

var UserModel = ((SocketHandler)item).Kullanici

你没有显示，但我假设 Clients 中的项目是 WebSocketHandler
