正确，最简单的方法是使用SignalR。请在https://www.nuget.org/packages/Microsoft.AspNet.SignalR/2.1.2中下载Microsoft
SignalR
在项目路径的单独文件夹中创建中心类，该中心称为hubs，将两个类文件添加到hubs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
// assembliesusing Microsoft.AspNet.SignalR;using RealTimeProgressBar;//call this method inside your working actionProgressHub.SendMessage("initializing and preparing", 2);鉴于
