You're not referencing the action method here:
您没有在此处引用操作方法：
action="Controllers/AccountController"
For starters, you don't need to specify Controllers/because the framework will find the controller for you. Indeed, the notion of a "folder" of controllers isn't known to the client/URL/etc. What you need to give it is a "route" to the specific action method.
对于初学者，您不需要指定，Controllers/因为框架会为您找到控制器。实际上，客户端/URL/等不知道控制器“文件夹”的概念。您需要给它的是特定操作方法的“路线”。
Since the MVC framework knows where the controllers are, you need only tell it which controller and which action method on that controller:
由于 MVC 框架知道控制器在哪里，您只需要告诉它哪个控制器以及该控制器上的哪个操作方法：
action="Account/LogOff"

The actionattribute is pointing to a wrong controller action. Your controller action is called LogOffand not AccountController. You should never be manually building <form>elements like that but always use the html helpers that are designed for this purpose:
该action属性指向错误的控制器操作。您的控制器操作被调用LogOff而不是AccountController。您永远不应该像这样手动构建<form>元素，而应始终使用专为此目的设计的 html 帮助程序：
@using (Html.BeginForm("LogOff", "Account"))
{
<button class="btn btn-inverse" title="Log out" type="submit">Log Off</button>
}
回答by Rohrbs
The form action should probably be /Account/LogOff
表单操作可能应该是 /Account/LogOff
< form class="float_left" action="/Account/Logoff" method="post">
<button class="btn btn-inverse" title="Log out" type="submit">Log Off</button>
</form>
Try putting this in the .cshtmlfile:
尝试将其放入.cshtml文件中：
@using (Html.BeginForm("LogOff", "Account"))
{
<button class="btn btn-inverse" title="Log out" type="submit">Log Off</button>
}
