SetBounds和SetBoundsCore有什么区别 [英] What is the difference between SetBounds and SetBoundsCore

问题描述

在WinForms中，可以使用 SetBounds 设置控件的边界，或者，如果创建了用户控件，则可以覆盖 SetBoundsCore .我想知道，他们俩都一样吗?还是有区别?

In WinForms you can set the bounds of a control using SetBounds, or if you have created a user control, you can override SetBoundsCore. I was wondering, does they both do the same or are there any differences?

推荐答案

首先 SetBounds 不是虚拟的，因此如果在设置边界时需要运行一些额外的代码，则唯一的选择是要覆盖 SetBoundsCore .

First of all SetBounds is not virtual, so if you need to run some extra code when the bounds is set, your only options is to override SetBoundsCore.

SetBounds 进行一些参数验证，并包含基于 BoundsSpecified 参数以正确大小调用 SetBoundsCore 的逻辑.它还确保除非大小实际更改，否则不要调用 SetBoundsCore .

SetBounds does some parameter validation, and contains the logic with regards to calling into SetBoundsCore with the correct size based on the BoundsSpecified parameter. It also makes sure not to call SetBoundsCore unless the size actually changes.

换句话说， SetBoundsCore 是实现的核心，而 SetBounds 是包含验证和一些其他内部逻辑的公共入口点.

In other words, SetBoundsCore is the meat of the implementation, while SetBounds is the public entry point which contain validation and some other housekeeping logic.
