在名为集线器的项目路径中的单独文件夹中创建集线器类，将两个类文件添加到集线器文件夹中

Startup.cs

using Owin;
using Microsoft.Owin;
[assembly: OwinStartup(typeof(SignalRChat.Startup))]
namespace SignalRChat
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            // Any connection or hub wire up and configuration should go here
            app.MapSignalR();
        }
    }
}

ProgressHub.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading;
using System.Web;
using Microsoft.AspNet.SignalR;

namespace RealTimeProgressBar
{
    public class ProgressHub : Hub
    {

        public string msg = "Initializing and Preparing...";
        public int count = 1;

        public static void SendMessage(string msg,int count)
        {
            var message = "Process completed for " + msg;
            var hubContext = GlobalHost.ConnectionManager.GetHubContext<ProgressHub>();
            hubContext.Clients.All.sendMessage(string.Format(message),count);
        }

        public void GetCountAndMessage()
        {
            Clients.Caller.sendMessage(string.Format(msg),count);
        }
    }
}

在控制器中，

// assemblies
using Microsoft.AspNet.SignalR;
using RealTimeProgressBar;   


//call this method inside your working action
ProgressHub.SendMessage("initializing and preparing",2);

在视图中，

<!--The jQuery library is required and is referenced by default in _Layout.cshtml. -->
<!--Reference the SignalR library. -->
<script src="~/Scripts/jquery.signalR-2.1.2.min.js"></script>
<!--Reference the autogenerated SignalR hub script. -->
<script src="~/signalr/hubs"></script>
<!--SignalR script to update the chat page and send messages.--> 
<script type="text/javascript">
  $(document).ready(function () {

    $("#progressBar").kendoProgressBar({
        min: 0,max: 100,type: "percent",});
});

function StartInvoicing()
{
    var progressNotifier = $.connection.progressHub;

    // client-side sendMessage function that will be called from the server-side
    progressNotifier.client.sendMessage = function (message,count) {
        // update progress
        UpdateProgress(message,count);
        //alert(message);
    };

    // establish the connection to the server and start server-side operation
    $.connection.hub.start().done(function () {
        // call the method CallLongOperation defined in the Hub
        progressNotifier.server.getCountAndMessage();
    });
}

// Update the progress bar 
function UpdateProgress(message,count) {
    var result = $("#result");
    result.html(message);
    $("#progressBar").data("kendoProgressBar").value(count);
}
</script>
