解决方法 要使用signalR来报告一个很长的任务的进度,你可以这样做(这只是一个例子来说明它是如何工作的)：

服务器部分

我们首先映射SignalR.

public class Startup{   public voID Configuration(IAppBuilder app)   {       // Any connection or hub wire up and configuration should go here       app.MapSignalR();   }}

我们创建一个Hub类(不要忘了安装signalr包)：

(如果要向所有连接的用户或特定的用户组报告进度,请查看：http://www.asp.net/signalr/overview/guide-to-the-api/working-with-groups)

在给定的例子中,它仅向Start函数的调用者报告进度.

public class MyHub : Hub{         public voID Start(string arg)    {        Task.Run(() =>        {            AVeryLongTask();        });    }    //simulate a long task    voID AVeryLongTask()    {        for (int i = 0; i < 10000; i++)        {            Thread.Sleep(100);                          ClIEnts.Caller.ReportProgress("AVeryLongTask",i * 100 / 10000);        }    }}

客户部分

在HTML中,您必须添加以下引用：

<!--Script references. --><!--Reference the jquery library. --><script src="Scripts/jquery-1.6.4.min.Js"></script><!--Reference the SignalR library. --><script src="/Scripts/jquery.signalR-2.0.0.Js"></script><!--Reference the autogenerated SignalR hub script. --><script src="/signalr/hubs"></script>

现在的Js部分是从中心获得进步：

$(function() {   // Declare a proxy to reference the hub.   var hub = $.connection.myHub;   // Create a function that the hub can call to report progress.   hub.clIEnt.reportProgress = function(functionname,progress) {     $('#progression').append('<li><strong>' + progress + '</strong>:&nbsp;&nbsp;' + functionname + '</li>');   };   // Start the connection.   $.connection.hub.start().done(function() {     $('#startlongprocess').click(function() {      //start the long process       hub.server.start("arg");       alert("started");     });   }); });

用于进度和开始按钮的HTML容器：

<div >       <input type="button" ID="startlongprocess" value="Send" />   <ul ID="progression"></ul></div>

如果您需要更多的解释,请不要犹豫.
