C＃如何设置透明键并且不允许点击？

Question

Well, I know how to set the transparent key,

but if i click the transparent region, it clicks through the form. is it possible to disabling click through?

hmm.. I think this question is similar as C# Winforms Transparent Control allowing Clickthrough

but i do not understand the answer, what value should i change to 1???

Answer 1

Opacity . Which controls general transparency of the form and it's only see-through, not click-through (unless 0 is used).

However, your form will be (very faintly) visible using that method.

It's a bit more complex to make only a region of the form transparent this way, though.
