什么是两者的区别：

e.Handled = true

和

e.SuppressKeyPress = true

我读过燮pressKey preSS电话e.Handled，但其他功能？

I've read that SuppressKeyPress calls e.Handled but else does it do?

推荐答案

根据此博客：的新键盘的API：KeyEventArgs.Sup pressKey preSS ：

问题是，处理的不采取未决的 WM_CHAR   消息已建成的消息队列 - 如此设置进行处理=   真不prevent密钥preSS的发生。

The problem is that "Handled" doesn't take care of pending WM_CHAR messages already built up in the message queue - so setting Handled = true does not prevent a KeyPress from occurring.

为了不打破任何人谁目前已经得到了e.Handled =   如此，我们需要添加一个名为燮pressKeyChar新的属性。如果我们   去的其他方式，如果处理一个的keydown突然开始   实际工作中，我们可能会破坏人谁不小心有这个设置为   真的。

In order not to break anyone who has currently got e.Handled = true, we needed to add a new property called SuppressKeyChar. If we went the other way, if "handling" a keydown suddenly started to actually work, we might break folks who accidentally had this set to true.
