如何防止 window 在 uwp 中的特定宽度和高度后收缩

Question

我正在开发 uwp 应用程序并希望使其响应。为此，我必须防止 window 在一定宽度和高度后缩小。有什么办法吗？我已经使用了 setpreferredminsize 属性，但它不起作用。 `

如果要限制最小window大小，可以使用SetPreferredMinSize方法来限制。

ApplicationView.GetForCurrentView().SetPreferredMinSize(
   new Size(
       300, // Width
       300 // Height
       )
   );

请注意

To remove the preferred minimum size and use and system default minimum size instead, set the Size value to "0,0".

The smallest allowed minimum size is 192 x 48 effective pixels. The largest allowed minimum size is 500 x 500 effective pixels. If you set a value outside of these bounds, it is coerced to be within the allowed bounds. (To learn about effective pixels, see Responsive design 101 for .)
