c# – 如何在定时器ASP.NET MVC上调用函数

因此,如果我们假设这样做,您想定期轮询一些控制器操作并更新视图上的信息,您可以使用setInterval javascript函数通过发送AJAX请求定期轮询服务器并更新UI：

window.setInterval(function() {
    // Send an AJAX request every 5s to poll for changes and update the UI
    // example with jquery:
    $.get('/foo',function(result) {
        // TODO: use the results returned from your controller action
        // to update the UI
    });
},5000);

如果另一方面你的意思是在服务器上定期执行一些任务,你可以使用这样的RegisterWaitForSingleObject方法：

var waitHandle = new AutoResetEvent(false);
ThreadPool.RegisterWaitForSingleObject(
    waitHandle,// Method to execute
    (state,timeout) => 
    {
        // TODO: implement the functionality you want to be executed
        // on every 5 seconds here
        // Important Remark: This method runs on a worker thread drawn 
        // from the thread pool which is also used to service requests
        // so make sure that this method returns as fast as possible or
        // you will be jeopardizing worker threads which could be catastrophic 
        // in a web application. Make sure you don't sleep here and if you were
        // to perform some I/O intensive operation make sure you use asynchronous
        // API and IO completion ports for increased scalability
    },// optional state object to pass to the method
    null,// Execute the method after 5 seconds
    TimeSpan.FromSeconds(5),// Set this to false to execute it repeatedly every 5 seconds
    false
);

如果您的意思是别的话,请不要犹豫,为您的问题提供更多细节.
