带锚的ASP.Net MVC RedirectToAction

我认为你应该使用这个Redirect方法Url.RouteUrl来实现它.

return Redirect(Url.RouteUrl(new { controller = "Thread", action = "ShowThreadLastPostPage", threadOid = threadId }) + "#" + postOid);

另一种选择Url.Action:

return Redirect(Url.Action("ShowThreadLastPostPage", "Thread", new { threadOid = threadOid }) + "last#" + postOid);
