@ViewBag.Name: @ViewBag.DateTime
控制器：
public ActionResult _Test(FormCollection form)
{
string name = form["Name"];
if (Request.IsAjaxRequest())
{
Thread thread = new Thread(() => RunThread());
thread.Start();
ViewBag.Name = name == null ? "No one, just refreshing" : name;
ViewBag.DateTime = DateTime.Now.ToShortTimeString();
return PartialView("_Test2");
}
else
{
return View();
}
}
此事件是来自业务逻辑的调用 .
public void ChangeEventFromBusinessLogic(object o)
{
//event from RunThread....
//refresch my view
}
视图中的ajax调用确实有效 . 如何在没有任何用户操作的情况下从业务逻辑刷新视图 .
我怎么做的？

您可以通过实现HTML 5功能WebSocketAPI来实现此目的 . 这是一种推送技术，允许服务器更新他们连接的客户端 .
SinglaR是用于ASP.Net应用程序的WebSocket的微软实现 .见Getting Started with SignalR
This will work only in the browser which supports WebsocketAPI
