C#:ResumeLayout(true)是否与ResumeLayout(false)+ PerformLayout()一样?

本文介绍了C#:ResumeLayout(true)是否与ResumeLayout(false)+ PerformLayout()一样?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我已经查看了生成的Form s和UserControl s设计器代码，在InitializeComponent()方法中，它们始终以

I have looked at the generated designer code of Forms and UserControls, and in the InitializeComponent() method they always start with

this.SuspendLayout();

并以

this.ResumeLayout(false); this.PerformLayout();

但是从我在这些方法的msdn文档中所看到的，并不会以

But from what I can see in the msdn documentation of those methods, wouldn't ending with

this.ResumeLayout(true); // Or just this.ResumeLayout()

完全一样吗?还是我在这里想念东西?

do the exact same thing? Or am I missing something here?

询问，因为我将以另一种方法添加一堆控件，并认为我应该执行suspend-resume例程以使其美观高效.但是无法弄清楚这两个方法调用的原因是什么，当您似乎只能使用一个方法时...

推荐答案

使用反射器:

this.ResumeLayout() is equal to this.ResumeLayout(true)

但是

this.ResumeLayout(true) is not equal to this.ResumeLayout(false) + this.PerformLayout()

原因: 当使用false调用ResumeLayout时，将循环遍历一个控件集合，并且LayoutEngine在布局中的每个控件上调用InitLayout.

Reason: When ResumeLayout is called with false, there is a control collection that is looped through and the LayoutEngine calls InitLayout on each of the controls in the layout.
