.NET WinForms KeyEventArgs.SuppressKeyPress: effect of setting it to True in the KeyUp event
问题
KeyEventArgs 类在 WinForms 中实现了布尔型的 SuppressKeyPress 属性。KeyEventArgs 为 KeyDown 和 KeyUp 事件提供数据。在 KeyDown 事件处理程序中将 SuppressKeyPress 属性设置为 True 可以抑制后续的 KeyPress 事件 - 这个目的很明确。但是在 KeyUp 事件的事件处理程序中将 SuppressKeyPress 设置为 True 会产生什么影响呢？
英文:
The KeyEventArgs class in WinForms implements the Boolean SuppressKeyPress property. KeyEventArgs provides data for the KeyDown and KeyUp events. The SuppressKeyPress property can be set to True in a KeyDown event handler to suppress the subsequent KeyPress event - this purpose is clear. But is there any effect of setting SuppressKeyPress to True in event handlers of the KeyUp event?

我完全同意所有评论者的观点，即“SuppressKeyPress”在“KeyUp”中是绝对无用的。正如@Jimi解释的那样，这个字段之所以出现在“KeyUp”中，仅因于Control类的特定内部架构。
英文:
I totally agree with all commenters that SuppressKeyPress is absolutely useless in KeyUp. As @Jimi explained, this field appears in KeyUp only because of the specific internal architecture of the Control class.
