Comment lier des boutons WPF aux commandes dans un ViewModelBase ?

<code class="language-csharp">public class CommandHandler : ICommand
{
    private Action _action;
    private Func<bool> _canExecute;

    public event EventHandler CanExecuteChanged
    {
        add { CommandManager.RequerySuggested += value; }
        remove { CommandManager.RequerySuggested -= value; }
    }

    public CommandHandler(Action action, Func<bool> canExecute)
    {
        _action = action;
        _canExecute = canExecute;
    }

    public bool CanExecute(object parameter) => _canExecute?.Invoke() ?? true;

    public void Execute(object parameter) => _action?.Invoke();
}</code>

<code class="language-csharp">public class ViewModelBase : INotifyPropertyChanged // Assuming INotifyPropertyChanged implementation
{
    private ICommand _clickCommand;

    public ICommand ClickCommand
    {
        get
        {
            return _clickCommand ?? (_clickCommand = new CommandHandler(MyAction, CanExecute));
        }
    }

    private void MyAction() { /* Your command logic here */ }
    private bool CanExecute() { /* Your canExecute logic here */ }

    // ... other properties and methods ...
}</code>

<code class="language-xaml"><Button Command="{Binding ClickCommand}" Content="Click Me"/></code>
