NaN布局测量崩溃 [英] NaN Layout Measurement Crash
问题描述
在我们相当复杂的应用程序中，我们遇到了布局管理崩溃的情况.
In our reasonably complex application, we are getting layout management crashes.
这些似乎不是特定于一段代码的.它们在不同的时间发生在不同的控件上，导致应用程序崩溃.在特定的硬件上，问题似乎更加明显.
These don't seem to be specific to one piece of code. They happen on different controls at different times, crashing the application. The problem seems to be more apparent on particular hardware.
一个示例堆栈如下:
One example stack looks like:
System.InvalidOperationException:元素"System.Windows.Controls.CheckBox"的布局度量替代不应返回NaN值作为其DesiredSize. ---> System.InvalidOperationException:元素"System.Windows.Controls.CheckBox"的布局测量覆盖
不应返回NaN值作为其DesiredSize.

我无法在一个简单的应用程序中解决此问题.
I haven't been able to repo this problem in a simple application.
有人有运气来应对这些情况吗?
Has anyone had any luck dealing with these situations?
推荐答案
请确保您所有的度量替代程序函数都只保留正值.而不是任何负，nan或负无穷大值.
make sure that all your measure overrider functions returens only positive values. and not any negative, nan or negative infinite values.
