如何显示异步结果在asp.netweb应用程序中哪一个是第一个？
我必须在三个类文件中发送三个异步请求，三个请求的响应时间不同，第一个是2秒，第二个是7秒，第三个是4秒，现在我必须在浏览器中显示第一个响应，在2秒后显示第三个响应，最后显示第二个响应，但现在我的结果在完成三个回复后一次显示所有回复，请给我任何建议，这是非常紧急的，请 我的代码是如何显示异步结果在asp.netweb应用程序中哪一个是第一个？,asp.net,asynchronous,Asp.net,Asynchronous,我必须在三个类文件中发送三个异步请求，三个请求的响应时间不同，第一个是2秒，第二个是7秒，第三个是4秒，现在我必须在浏览器中显示第一个响应，在2秒后显示第三个响应，最后显示第二个响应，但现在我的结果在完成三个回复后一次显示所有回复，请给我任何建议，这是非常紧急的，请 我的代码是 public delegate string AsyncMethodCaller(string name); public delegate string AsyncMethodCallertest(st

hemanth我认为问题的根源在于理解ASP.Net请求会发生什么 每个页面都有其生命周期，其中包括一系列事件。每个请求都由来自当前应用程序AppDomain的工作线程处理。在页面管道完成之前，不会将响应发送给用户 关于线程： 可以在
