我如何从当前上下文中获取AspNetWebSocketContext？

Question

我正在使用Microsoft webscoket实现ASP.net websocket服务器。我有一个将数据发送到客户端的功能。以下是课程。

public class MyWebSocketHandler : IHttpHandler
    {

        public void ProcessRequest(HttpContext context)
        {
            if (context.IsWebSocketRequest)
            {
                context.AcceptWebSocketRequest(DoTalking);

            }
        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }

        public async Task DoTalking(AspNetWebSocketContext context)
        {
            WebSocket socket = context.WebSocket;
            while (true)
            {
                ArraySegment<byte> buffer = new ArraySegment<byte>(new byte[1024]);
                WebSocketReceiveResult result = await socket.ReceiveAsync(buffer, CancellationToken.None);
                if (socket.State == WebSocketState.Open)
                {
                    string userMessage = Encoding.UTF8.GetString(buffer.Array, 0, result.Count);
                    userMessage = "Message from client : " + userMessage;

                }
                else
                {
                    break;
                }
            }
        }

        public async Task SendToClient(AspNetWebSocketContext context)
        {
            WebSocket socket = context.WebSocket;
            //WebSocket socket = context.WebSocket;
            ArraySegment<byte> buffer = new ArraySegment<byte>(new byte[1024]);
            buffer = new ArraySegment<byte>(Encoding.UTF8.GetBytes(message));
            await socket.SendAsync(buffer, WebSocketMessageType.Text, true, CancellationToken.None);
        }

        public void callSendToClient()
        {
                var task = SendToClient(Problem is here!);
                task.Wait();  
        }

        private string message { get; set; }
    }
}

我的问题是当我调用SendToClient方法时如何获取AspNetWebSocketContext？我被困在这一点上。其实我想从另一个.aspx页面调用SendToClient（）方法。需要一些帮助。
