我有一个有关刷新画布的问题。 WinForms中有.Refresh()或.Clear(),但是WPF呢?
我看了一些方法,但是对我没有任何帮助。
情况是我的画布包含textBox和Button。当我单击按钮时,我可以画一些椭圆。
而且,我每次单击按钮后都需要清除这些省略号,但无需从此Canvas清除textBox和Button!
我的WPF Xaml:



您可以使用以下代码分隔元素:
var can2 = can.Children.OfType ();
上面的代码在“ can”画布中选择所有“椭圆”。
您可以像这样从画布中删除它们:
foreach(can2中的var元素)
{
can.Children.Remove(element);
}
现在,“画布”中没有椭圆了。
希望这对您有所帮助。
