WPF實現(xiàn)窗體亞克力效果的示例代碼
更新時間：2022年10月04日 07:34:25 作者：驚鏵
這篇文章主要為大家詳細(xì)介紹了如何利用WPF實現(xiàn)窗體亞克力效果，文中的示例代碼講解詳細(xì)，對我們學(xué)習(xí)或工作有一定幫助，感興趣的小伙伴可以了解一下
WPF 窗體設(shè)置亞克力效果
框架使用大于等于.NET40。
Visual Studio 2022。
項目使用 MIT 開源許可協(xié)議。
WindowAcrylicBlur 設(shè)置亞克力顏色。
Opacity 設(shè)置透明度。
實現(xiàn)代碼
1） 準(zhǔn)備WindowAcrylicBlur.cs如下：

2） 使用AcrylicBlurWindowExample.xaml如下：

3） 使用AcrylicBlurWindowExample.xaml.cs如下：
using?System.Windows;
using?System.Windows.Input;
using?WPFDevelopers.Samples.Helpers;
namespace?WPFDevelopers.Samples.ExampleViews
{
????///?<summary>
????///?AcrylicBlurWindowExample.xaml?的交互邏輯

????????public?ICommand?CloseCommand?=>?new?RelayCommand(obj?=>
????????{
???????????Close();
????????});
????}
