Question

我有一个WPF应用程序，有几个人使用，有时我收到一封有这个错误的电子邮件，但我无法重现它。任何人都知道该怎么做才能得到这个错误？

鼠标输入正常但Touch会导致此异常。在我的情况下，禁用RealTimeStylus似乎修复了这个特殊问题。

请参阅http://referencesource.microsoft.com/#PresentationCore/Core/CSharp/System/Windows/Input/Stylus/StylusTouchDevice.cs

取自相关问题，该问题具有类似的堆栈跟踪但由RealTimeStylus引起的异常异常。 https://stackoverflow.com/a/15879522/3304592

WPF - StylusLogic - 索引超出范围
