WP7 RTM Emulator正在右侧显示framecounter和dx信息-这是默认值吗?

模拟器没有。默认情况下,应用程序是。(如果附加了调试器)

如果你往里面看应用程序xaml.cs在自动生成的构造函数中可以找到以下代码:

        // Show graphics profiling information while debugging.
        if (System.Diagnostics.Debugger.IsAttached)
        {
            // Display the current frame rate counters.
            Application.Current.Host.Settings.EnableFrameRateCounter = true;

            // Show the areas of the app that are being redrawn in each frame.
            //Application.Current.Host.Settings.EnableRedrawRegions = true;

            // Enable non-production analysis visualization mode, 
            // which shows areas of a page that are being GPU accelerated with a colored overlay.
            //Application.Current.Host.Settings.EnableCacheVisualization = true;
        }

如果您想关闭enableframeratecounter,您可以将其注释掉,也可以取消对其他计数器的注释以获取更多内容。
