属性

注解

当此属性返回 true 时,控件将被释放,并且不再被引用为有效的 Windows 控件。When this property returns true, the control is disposed of and can no longer be referenced as a valid Windows control. 即使控件的实例被释放,它仍将保留在内存中,直到通过垃圾回收从内存中删除。Even though the instance of a control is disposed of, it is still maintained in memory until it is removed from memory through garbage collection. 释放控件后,将无法调用其 RecreateHandle 方法。When a control is disposed, you cannot call its RecreateHandle method.
