C# UWP app.cs文件继承来自xaml.cs的静态变量
我已经创建了PlayPage.xaml、PlayPage.xaml.cs和Game.cs文件。 PlayPage.xaml.cs有两个变量，windowWidth和windowHeight 我想从Game.cs访问两个公共静态变量 Game.cs:C# UWP app.cs文件继承来自xaml.cs的静态变量,c#,xaml,uwp,C#,Xaml,Uwp,我已经创建了PlayPage.xaml、PlayPage.xaml.cs和Game.cs文件。 PlayPage.xaml.cs有两个变量，windowWidth和windowHeight 我想从Game.cs访问两个公共静态变量 Game.cs: namespace UwpApp { class Game { static Rectangle rectangle; PlayPage pg = new PlayPage(); //

如图所示，图片中的错误是由于无限递归造成的。游戏的构造函数实例化一个新的PlayPage。PlayPage的构造函数实例化了一个新游戏。它实例化了一个新的PlayPage。它实例化了一个新游戏。不断地 静态成员是通过类名而不是实例访问的。像这样：
PlayPage.windowWidth
此外，UWP中最好避免使用静态数据。
