推荐答案

当Visible属性变为true时，将创建句柄.如果在表单构造函数中将其设置为true(最常见的控件情况)，则将在创建表单时发生，发生在Load事件之前.再次将Visible设置为false不会破坏该句柄.

The handle is created when the Visible property becomes true. If it was set to true in the form constructor, the most common case for controls, that will happen when the form is created, right before the Load event. Setting Visible to false again doesn't destroy the handle.
