如何在C#中使用SignalR向特定用户发送数据？

using Microsoft.AspNet.SignalR;

public class MyHub : Hub
{
    public void SendDataToUser(string userId, string data)
    {
        Clients.User(userId).sendData(data);
    }
}

using Microsoft.AspNet.SignalR;
using Microsoft.Owin;
using Owin;

[assembly: OwinStartup(typeof(YourNamespace.Startup))]
namespace YourNamespace
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            app.MapSignalR();
        }
    }
}

<script src="~/Scripts/jquery.signalR-2.4.2.min.js"></script>
<script src="~/signalr/hubs"></script>

<script>
    var hub = $.connection.myHub;

    hub.client.sendData = function (data) {
        // 处理接收到的数据
    };

    $.connection.hub.start().done(function () {
        // 连接成功后的操作
    });
</script>

var hubContext = GlobalHost.ConnectionManager.GetHubContext<MyHub>();
hubContext.Clients.User(userId).sendData(data);
