问题 I can decorate an action either with the [AcceptVerbs(HttpVerbs.Post)]/[AcceptVerbs(HttpVerbs.Get)] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(string title) { // Do Something... } or with the [HttpPost]/[HttpGet] attributes [HttpPost] public ActionResult Create(string title) { // Do Something... } Are they different? 回答1: Nothing.

阅读更多关于 What is the best option for transcribing speech-to-text in a asp.net web app?

I am building a web app for recording voice messages and am looking for the best options for converting the voice messages to text.

On page 132, in accordance with the author's recommendation, I downloaded the ASP.NET MVC Futures assembly, and added it to my MVC project. Then, without encouragement from the author , I downloaded, installed, and incorporated the ASP.NET MVC2 Preview 1 dlls into my project. Now, I can no longer load the website. That is, when I hit F5 in Visual Studio, I get this error. In retrospect, I think it was a really bad idea to

阅读更多关于 Firefox 6 Infinite Page Refresh With Page With Hash Tags

When Firefox updated to version 6 recently, a site I'm working on severely broke. The site operates normally when browsing to any page without a hash tag but if you try to navigate to a page with a hash tag (e.g. #test ) or refresh the page once a hash tag was applied, the page refreshes as quickly as it can infinitely. This is a Asp.Net MVC 2 site created around a year and a half ago. frank hadder Turns out, this is an issue with an old version of MicrosoftAjax.js (the one that comes installed with Asp.Net MVC 2).

Should I maybe try the json.net library? public class JsonFilter : ActionFilterAttribute { public string Param { get; set; }
