一种C# Winform的UI处理

news 2025/7/7 11:01:50

效果

·圆角 + 阴影 +突出按钮

说明

这是一种另类的处理，不是多层窗口也不是WPF 。这种方式的特点是比较简单，例如圆角、阴影、按钮等特别容易修改过。其实就是html + css + DirectXForm。

在VS中如下

圆角和阴影

然后编辑这个窗体的Html模板，例如圆角和阴影的调整可以修改CSS中的

border-radius: 14px;
box-shadow: 0px 8px 24px 0px rgba(0, 0, 0, 0.2);

我要想一个小圆角可以改成 border-radius: 6px;

中间的按钮

中间的按钮的CSS

.play_btn
{
   position: fixed;
   left: 50%;
   margin-left: -39px;
   cursor: pointer;
   bottom: 22px;
   display: inline-block;
   width: 78px;
   height: 78px;
   background-color: rgb(255, 255, 255);
   border-radius: 39px;
   box-shadow: 4px 8px 8px 0px rgba(80, 80, 80, 0.55);
}
如果你想要个丑点的阴影，可以改成

box-shadow: 4px 8px 8px 0px rgba(255, 0, 0, 0.75);

反正就是CSS

窗体可以随便放控件
