1.引用类

using System.ComponentModel

2.创建Command自定义类

 public class DelegateCommand : ICommand{public bool CanExecute(object parameter){if (CanExecuteFunc == null)return true;return this.CanExecuteFunc(parameter);}public event EventHandler CanExecuteChanged;public void Execute(object parameter){if (ExecuteAction == null){return;}this.ExecuteAction(parameter);}public Action<object> ExecuteAction { get; set; }public Func<object, bool> CanExecuteFunc { get; set; }}

3.ViewModel层实现数据绑定、Command事件点击

public class MainViewModel : INotifyPropertyChanged
{public event PropertyChangedEventHandler PropertyChanged;public MainViewModel(){#必需初始化时就加载才生效this.SelectFileNameCommand = new DelegateCommand();this.SelectFileNameCommand.ExecuteAction = new Action<object>(this.SelectFileName);}/// <summary>/// 当前时间/// </summary>private string currentTimer;public string CurrentTimer{get{return currentTimer;}set{currentTimer = value;if (this.PropertyChanged != null){this.PropertyChanged.Invoke(this, new PropertyChangedEventArgs("CurrentTimer"));}}}public DelegateCommand DoubleClickNotifyCommand { get; set; }private void DoubleClickNotify(object parameter){}}

4.界面按钮绑定事件

<ButtonMargin="0,0,5,0"Command="{Binding DoubleClickNotifyCommand }"Content="{DynamicResource Setting_File}"FontSize="20"Foreground="White" />
