如何在c# System.Web.Http.ApiController中实现信令R客户端

using System;
using System.Threading.Tasks;
using Microsoft.AspNet.SignalR.Client;

namespace SignalRClient
{
    public class SignalRClient
    {
        private HubConnection _hubConnection;
        private IHubProxy _hubProxy;

        public async Task Connect()
        {
            try
            {
                _hubConnection = new HubConnection("http://your-signalr-server-url");
                _hubProxy = _hubConnection.CreateHubProxy("your-hub-name");

                _hubProxy.On<string>("methodName", parameter => {
                    // 处理信令R服务端返回的数据
                });

                await _hubConnection.Start();
                // 连接成功处理
            }
            catch (Exception ex)
            {
                // 连接失败处理
            }
        }

        public async Task SendMessage(string message)
        {
            try
            {
                await _hubProxy.Invoke("methodName", message);
            }
            catch (Exception ex)
            {
                // 调用失败处理
            }
        }
    }
}
