代碼如下

一、CycleLoading.cs 代碼如下

using System.Windows; using System.Windows.Controls;namespace WPFDevelopers.Controls {public class CycleLoading : ContentControl{static CycleLoading(){DefaultStyleKeyProperty.OverrideMetadata(typeof(CycleLoading), new FrameworkPropertyMetadata(typeof(CycleLoading)));}public override void OnApplyTemplate(){base.OnApplyTemplate();}public double MaxValue{get { return (double)GetValue(MaxValueProperty); }set { SetValue(MaxValueProperty, value); }}// Using a DependencyProperty as the backing store for MaxValue. This enables animation, styling, binding, etc...public static readonly DependencyProperty MaxValueProperty =DependencyProperty.Register("MaxValue", typeof(double), typeof(CycleLoading), new PropertyMetadata(100d));public double Value{get { return (double)GetValue(ValueProperty); }set { SetValue(ValueProperty, value); }}// Using a DependencyProperty as the backing store for Value. This enables animation, styling, binding, etc...public static readonly DependencyProperty ValueProperty =DependencyProperty.Register("Value", typeof(double), typeof(CycleLoading), new PropertyMetadata(0d, OnValuePropertyChangedCallBack));internal string ValueDescription{get { return (string)GetValue(ValueDescriptionProperty); }set { SetValue(ValueDescriptionProperty, value); }}// Using a DependencyProperty as the backing store for ValueDescription. This enables animation, styling, binding, etc...internal static readonly DependencyProperty ValueDescriptionProperty =DependencyProperty.Register("ValueDescription", typeof(string), typeof(CycleLoading), new PropertyMetadata(default(string)));private static void OnValuePropertyChangedCallBack(DependencyObject d, DependencyPropertyChangedEventArgs e){if (!(d is CycleLoading loading))return;if (!double.TryParse(e.NewValue?.ToString(), out double value))return;if (value >= loading.MaxValue){value = loading.MaxValue;if (loading.IsStart)loading.IsStart = false;}else{if (!loading.IsStart)loading.IsStart = true;}double dValue = value / loading.MaxValue;loading.ValueDescription = dValue.ToString("P0");}public bool IsStart{get { return (bool)GetValue(IsStartProperty); }set { SetValue(IsStartProperty, value); }}// 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(CycleLoading), new PropertyMetadata(true));public string LoadTitle{get { return (string)GetValue(LoadTitleProperty); }set { SetValue(LoadTitleProperty, value); }}// Using a DependencyProperty as the backing store for LoadTitle. This enables animation, styling, binding, etc...public static readonly DependencyProperty LoadTitleProperty =DependencyProperty.Register("LoadTitle", typeof(string), typeof(CycleLoading), new PropertyMetadata(default(string)));} }

二、CycleLoading.xaml?代碼如下?

三、RollLoading 代碼如下?

using System.Windows; using System.Windows.Controls; using System.Windows.Media;namespace WPFDevelopers.Controls {public class RollLoading : ContentControl{static RollLoading(){DefaultStyleKeyProperty.OverrideMetadata(typeof(RollLoading), new FrameworkPropertyMetadata(typeof(RollLoading)));}public override void OnApplyTemplate(){base.OnApplyTemplate();}public Color ForegroundColor{get { return (Color)GetValue(ForegroundColorProperty); }set { SetValue(ForegroundColorProperty, value); }}// Using a DependencyProperty as the backing store for ForegroundColor. This enables animation, styling, binding, etc...public static readonly DependencyProperty ForegroundColorProperty =DependencyProperty.Register("ForegroundColor", typeof(Color), typeof(RollLoading), new PropertyMetadata(Colors.Red));public bool IsStart{get { return (bool)GetValue(IsStartProperty); }set { SetValue(IsStartProperty, value); }}// 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(RollLoading), new PropertyMetadata(true));} }

四、RollLoading.xaml?代碼如下?

五、LoadingExample.xaml 代碼如下?

<wpfdev:CycleLoading Value="50" LoadTitle="Loading...." Width="200"><TextBlock Text="activity"/></wpfdev:CycleLoading><wpfdev:RollLoading IsStart="true" HorizontalContentAlignment="Center" VerticalContentAlignment="Center"Width="200"><TextBlock Text="Loading activity..."/></wpfdev:RollLoading>
