属性值

注解

当此属性返回true，控件被释放，不能再作为有效的 Windows 控件被引用。When this property returns true, the control is disposed of and can no longer be referenced as a valid Windows control. 即使控件的实例已释放，它仍将保留在内存中直到从通过垃圾回收的内存中删除。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. 当释放一个控件时，不能调用其RecreateHandle方法。When a control is disposed, you cannot call its RecreateHandle method.
