网页渲染时间MVC

问：我如何计算总花费的时间来呈现一个MVC页面，并显示在主网页上的时间

Q: How do I calculate the total time it takes to render an MVC page and display the time on the master page.

在Asp.net Web窗体我创建了一个基本页类，像这样：

In Asp.net Web Form I created a Base page class like so:

public class PageBase : System.Web.UI.Page
{      
    private DateTime startTime = DateTime.Now;
    private TimeSpan renderTime;   
    public DateTime StartTime
    {
        set { startTime = value; }
        get { return startTime; }
    }  
    public virtual string PageRenderTime
    {
        get
        {
            renderTime = DateTime.Now - startTime;
            return renderTime.Seconds + "." + renderTime.Milliseconds + " seconds";
        }
    }       
}

我然后调用该方法在我的母版页，像这样：

I would then call the method on my Master Page like so:

<div id="performance">
     <% =PageRenderTime %>
</div>

问：我如何完成同样的事情与MVC框架

Q: How do I accomplish the same thing with the MVC Framework?

问：MVC框架我在哪里设置开始时间第一次创建页面时？

Q: With the MVC framework where do I set the start time when a page is first created?
