wpf工程中加入Hardcodet.NotifyIcon.Wpf生成托盘

1、在项目中用nuget引入Hardcodet.NotifyIcon.Wpf。如下图所示。

2、在App.xaml中创建托盘界面，代码是写在 App.xaml 里面

注意在application中一定要加入这一行代码： xmlns:tb="http://www.hardcodet.net/taskbar"

然后在中加入如下代码
 

    
        "false" x:Key="SysTrayMenu">
            "25" Header="显示界面" Command="{Binding NotifyCommand}" CommandParameter="1">
            
            "25" Header="隐藏界面" Command="{Binding NotifyCommand}" CommandParameter="0">
            
            
            "25" Header="退出服务" Command="{Binding NotifyCommand}" CommandParameter="99">
            
        
        "Taskbar" ToolTipText=""
                    DoubleClickCommand="{Binding NotifyCommand}"  DoubleClickCommandParameter="1"
                    ContextMenu="{StaticResource SysTrayMenu}" IconSource="/jqsw.ico">
            
                "LightYellow" CornerRadius="5" Opacity="0.8" Padding="10">
                    "Vertical">
                        "温湿度数据采集服务网口版" Foreground="Red"/>
                        
                    
                
            
        
    

3、创建ViewModelBase类。再创建TaskbarIconViewModel类继承ViewModelBase类

internal class ViewModelBase : INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler  PropertyChanged ;
        protected void RaisePropertyChanged(string property)
        {
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(property));
        }
    }
 
 
 
 
 
internal class TaskbarIconViewModel : ViewModelBase
    {
        private string systemTime;
        public string SystemTime
        {
            get { return systemTime; }
            set { systemTime = value; RaisePropertyChanged("SystemTime"); }
        }
        public DelegateCommand NotifyCommand
        {
            get
            {
                return new DelegateCommand((type) =>
                {
                    if (type.ToString() == "0")
                        Application.Current.MainWindow.Hide();
                    if (type.ToString() == "1")
                    {
                        Application.Current.MainWindow.Show();
                        Application.Current.MainWindow.Activate();
                    }
                    if (type.ToString() == "99")
                        Application.Current.Shutdown();
                });
            }
        }
    } 

、在App.xaml.cs中写入如下代码：

private static System.Threading.Mutex mutex;
        protected override void OnStartup(StartupEventArgs e)
        {
            mutex = new System.Threading.Mutex(true, "TemCollSrvTwo");
            if (mutex.WaitOne(0, false))
            {
                base.OnStartup(e);
            }
            else
            {
                MessageBox.Show("程序已经在运行！", "提示");
                this.Shutdown();
            } 
 
            mTaskbarIcon = (TaskbarIcon)FindResource("Taskbar");
            mTaskbarIcon.DataContext = new TaskbarIconViewModel();
        }
        public static TaskbarIcon  mTaskbarIcon;
