I want to send some kind of timer to server to all connected clients. I was able to do this on button click. But what I really need is to send this timer every second automatically.
我想给所有连接的客户端发送一些定时器。我可以在点击按钮的时候做这个。但我真正需要的是每秒钟自动发送这个计时器。

using System;
using Microsoft.AspNet.SignalR.Hubs;
using System.Threading;
namespace SignalRChat
{
[HubName("myChatHub")]
public class LetsChat : Hub
{
DateTime dateTime2 = DateTime.Now;
string dateTime1 = "11.04.2016 15:49:00";
public void send(string message)
{
//Thread.Sleep(1000);
var diffInSeconds = (Convert.ToDateTime(dateTime1) - dateTime2).TotalSeconds;
Clients.All.addMessage(message);
Clients.All.addTest(diffInSeconds.ToString());
//Clients.All.addTest(dateTime1.ToString());
}
}
}

You can make use of System.Timers.Timer
to do that:
你可以使用system . timer。定时器:
public class LetsChat : Hub
{
private static readonly System.Timers.Timer _timer = new System.Timers.Timer();
static LetsChat()
{
_timer.Interval = 1000;
_timer.Elapsed += TimerElapsed;
_timer.Start();
}
static void TimerElapsed(object sender, System.Timers.ElapsedEventArgs e)
{
var hub = GlobalHost.ConnectionManager.GetHubContext<LetsChat>();
var diffInSeconds = (Convert.ToDateTime(dateTime1) - dateTime2).TotalSeconds;
hub.Clients.All.addMessage("Message");
hub.Clients.All.addTest(diffInSeconds.ToString());
}
public void send(string message)
{
//Thread.Sleep(1000);
var diffInSeconds = (Convert.ToDateTime(dateTime1) - dateTime2).TotalSeconds;
Clients.All.addMessage(message);
Clients.All.addTest(diffInSeconds.ToString());
//Clients.All.addTest(dateTime1.ToString());
}
}
