this.invalidate（）在c＃中的网站应用程序中显示错误 [英] this.invalidate() show error in website application in c#

问题描述

这是网站的汇编参考

推荐答案

使控件的整个表面无效并导致重绘控件。

命名空间：System.Windows.Forms

汇编：System.Windows.Forms（在System.Windows.Forms.dll中）



调用Invalidate方法不会强制执行同步绘制;要强制执行同步绘制，请在调用Invalidate方法后调用Update方法。如果在没有参数的情况下调用此方法，则会将整个客户区添加到更新区域。

Invalidates the entire surface of the control and causes the control to be redrawn.
Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)

Calling the Invalidate method does not force a synchronous paint; to force a synchronous paint, call the Update method after calling the Invalidate method. When this method is called with no parameters, the entire client area is added to the update region.
