1 ）RingLoading.cs代码如下；

using System.Windows;
using System.Windows.Controls;

namespace WPFDevelopers.Controls
{
    public class RingLoading : Control
    {
        // Using a DependencyProperty as the backing store for IsStart.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty IsStartProperty =
            DependencyProperty.Register("IsStart", typeof(bool), typeof(RingLoading), new PropertyMetadata(default));

        // Using a DependencyProperty as the backing store for ProgressValue.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty ProgressValueProperty =
            DependencyProperty.Register("ProgressValue", typeof(double), typeof(RingLoading),
                new PropertyMetadata(0d, OnProgressValueChangedCallBack));

        // Using a DependencyProperty as the backing store for Progress.  This enables animation, styling, binding, etc...
        internal static readonly DependencyProperty ProgressProperty =
            DependencyProperty.Register("Progress", typeof(string), typeof(RingLoading), new PropertyMetadata(default));

        // Using a DependencyProperty as the backing store for Maximum.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty MaximumProperty =
            DependencyProperty.Register("Maximum", typeof(double), typeof(RingLoading),
                new PropertyMetadata(100d, OnMaximumPropertyChangedCallBack));

        // Using a DependencyProperty as the backing store for Description.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty DescriptionProperty =
            DependencyProperty.Register("Description", typeof(string), typeof(RingLoading),
                new PropertyMetadata(default));

        static RingLoading()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(RingLoading),
                new FrameworkPropertyMetadata(typeof(RingLoading)));
        }

        public bool IsStart
        {
            get => (bool)GetValue(IsStartProperty);
            set => SetValue(IsStartProperty, value);
        }


        public double ProgressValue
        {
            get => (double)GetValue(ProgressValueProperty);
            set => SetValue(ProgressValueProperty, value);
        }


        internal string Progress
        {
            get => (string)GetValue(ProgressProperty);
            set => SetValue(ProgressProperty, value);
        }


        public double Maximum
        {
            get => (double)GetValue(MaximumProperty);
            set => SetValue(MaximumProperty, value);
        }

        public string Description
        {
            get => (string)GetValue(DescriptionProperty);
            set => SetValue(DescriptionProperty, value);
        }

        private static void OnProgressValueChangedCallBack(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            if (!(d is RingLoading control))
                return;

            if (!double.TryParse(e.NewValue?.ToString(), out var value))
                return;

            var progress = value / control.Maximum;
            control.SetCurrentValue(ProgressProperty, progress.ToString("P0"));
        }

        private static void OnMaximumPropertyChangedCallBack(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            if (!(d is RingLoading control))
                return;

            if (!double.TryParse(e.NewValue?.ToString(), out var maxValue))
                return;

            if (maxValue <= 0)
                return;

            var progress = control.ProgressValue / maxValue;
            control.SetCurrentValue(ProgressProperty, progress.ToString("P0"));
        }
    }
}

2 ）RingLoading.xaml代码如下；

3 ）RingLoadingExample.xaml代码如下；

<UserControl x:Class="WPFDevelopers.Samples.ExampleViews.RingLoadingExample"

             xmlns:wpfdev="https://github.com/WPFDevelopersOrg/WPFDevelopers"
             xmlns:local="clr-namespace:WPFDevelopers.Samples.ExampleViews"
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800">

其实只留一组，甚至把那个东西的头部删掉其实就好多了，最好圆弧的长度还能随着时间变长变短。。。。

就用 windows start 那个 loading 不香吗

@marcong95 还可以变粗变细，变直变弯

很酷诶...WPF 我用了一段时间但是完全没搞懂它的高级样式和动画，现在 winui 3 也出了，不知道该学哪个了

@vone 哈哈哈哈哈

@villivateur 欢迎使用哈，https://github.com/WPFDevelopersOrg 这个组织下都是关于 WPF 和 MAUI 的项目。有问题及时反馈哈。

@stoluoyu 哈哈哈哈，后期应该会增加任务完成关闭。

@NGXDLK 是这样的。

@lifeintools 可以复制源码魔改起来。

@xyx0826 maui 跨平台，win10 之前的系统。动画和高级样式多写几次就熟悉了。“https://github.com/WPFDevelopersOrg” 这个组织下 也有 maui 项目。

WPF 设置样式（ StyleSetter ）和动画（ StoryBorad ）太累了，我已经放弃了，现在都用网页做 UI ，通过 websocket 链接到本地

@ragnaroks 熟悉了就还好，也是不错的选择。👍
