C# 在XNA中更改分辨率-之后屏幕变黑

我正在用最新的XNA（C#）编写一个2D游戏。我正在对旧代码进行一次彻底的修改，并且刚刚添加了一些按钮来更改分辨率。然而，在切换全屏模式或更改窗口大小/分辨率后，屏幕将永远是黑色（我的清晰屏幕调用的颜色），尽管游戏仍在运行，因为我可以通过按键退出。 这在我以前的版本中并没有发生过——一切都很好——但在我能找到的相关代码中并没有区别。但是我重新加载了我的图形，用我自己的纹理加载器而不是内容加载器-这会是问题吗

如果没有其他选项，是否有一个简单的方法使游戏重新启动，因为图形正常，并在重新启动后处于选定的格式

我的代码是：

 public override void Click()
    {
        base.Click();
        Settings.Default.screenWidth = resolution[0];
        Settings.Default.screenHeight = resolution[1];
        Settings.Default.Save();
        Variables.screenWidth = Settings.Default.screenWidth;
        Variables.screenHeight = Settings.Default.screenHeight;

        Game1.graphics.PreferredBackBufferWidth = Variables.screenWidth;
        Game1.graphics.PreferredBackBufferHeight = Variables.screenHeight;
        Game1.graphics.ApplyChanges();
    }

谢谢

编辑：以下建议中的工作代码-可能不是最有效的，但它可以工作
