标题: WPF自定义控件之消息提示
创建消息提示控件

1. internal class Message : ContentControl
2.     {
3.    
4.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />public int Time { get; set; }
6.    
7.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />[Bindable(true)]
8.    
9.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />public MessageType MessageType { get { return (MessageType)GetValue(MessageTypeProperty); } set { SetValue(MessageTypeProperty, value); } }
10.    
11.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />public static readonly DependencyProperty MessageTypeProperty = DependencyProperty.Register("MessageType", typeof(MessageType), typeof(Message), new PropertyMetadata(default(MessageType)));
13.    
14.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />internal Message()
15.    
16.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />{
17.    
18.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />    Loaded += Message_Loaded;
19.    
20.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />}
22.    
23.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />private async void Message_Loaded(object sender, System.Windows.RoutedEventArgs e)
24.    
25.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />{
26.    
27.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />    if (Parent is MessageHost host)
28.    
29.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />    {
30.    
31.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />   
32.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />await Task.Delay(Time);
33.    
34.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />   
35.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />host.Items.Remove(this);
36.    
37.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />    }
38.    
39.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />}
40.     }

消息提示控件

1.    
2.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />

复制代码

消息提示控件容器样式创建消息通知类

1. public class MessageManage    {   
2.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />internal static Dictionary MessageHosts { get; set; } = MessageHosts ?? new Dictionary();   
3.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />public static void Default(string message, string token = null, int time = 3000)   
4.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />{   
5.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />    Show(message, MessageType.Default, token, time);   
6.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />}   
7.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />public static void Success(string message, string token = null, int time = 3000)   
8.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />{   
9.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />    Show(message, MessageType.Success, token, time);   
10.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />}   
11.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />public static void Warning(string message, string token = null, int time = 3000)   
12.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />{   
13.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />    Show(message, MessageType.Warning, token, time);   
14.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />}   
15.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />public static void Error(string message, string token = null, int time = 3000)   
16.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />{   
17.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />    Show(message, MessageType.Error, token, time);   
18.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />}   
19.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />private static void Show(string message, MessageType messageType, string token, double time)   
20.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />{   
21.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />    if (!MessageHosts.ContainsKey(token)) return;   
22.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />    var messageHost = MessageHosts[token];   
23.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />    messageHost.Dispatcher.BeginInvoke( (Action)(() =>   
24.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />    {   
25.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />   
26.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />messageHost.Items.Add(new Message() { MessageType = messageType, Content = message, Time = time, Uid = Guid.NewGuid().ToString() });   
27.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />    }));   
28.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />}    }

复制代码

消息通知使用示例：

在app.xaml中引入资源

1.    
2.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />   
3.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />   
4.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />   
5.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />   
6.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />   
7.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />   
8.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />   

复制代码

 MainWindow.xaml

1.    
2.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />   
3.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />   

复制代码

1. public partial class MainWindow : Window    {   
2.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />public MainWindow()   
3.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />{   
4.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />    InitializeComponent();   
5.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />}   
6.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />private void Button_Click(object sender, RoutedEventArgs e)   
7.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />{   
8.     <Style BasedOn="{StaticResource MessageHostStyle}" TargetType="xy:MessageHost" />    MessageManage.Success("点击了测试", "MainmessageToken");
9. 　　　　　}
10. 　　 }

复制代码

效果：

 通俗点讲就是在想要拥有提示的页面添加一个容器，容器中塞入消息提示控件，消息提示控件在指定时间之后从容器中移除；
MessageManage类通过token进行查找到指定容器进行塞入；
也可以全局使用一个消息容器进行提示；根据需求进行改造。
