如何在Xamarin表单中使用绑定发送数据和make命令？

// 创建一个ViewModel类
public class MyViewModel : INotifyPropertyChanged
{
    private string _data;
    public string Data
    {
        get { return _data; }
        set
        {
            if (_data != value)
            {
                _data = value;
                OnPropertyChanged(nameof(Data));
            }
        }
    }

    public ICommand MakeCommand { get; }

    public MyViewModel()
    {
        MakeCommand = new Command(ExecuteMakeCommand);
    }

    private void ExecuteMakeCommand()
    {
        // 执行make命令的逻辑
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

// 在Xamarin表单中使用绑定
public class MyPage : ContentPage
{
    public MyPage()
    {
        var viewModel = new MyViewModel();

        var label = new Label();
        label.SetBinding(Label.TextProperty, nameof(MyViewModel.Data));

        var button = new Button();
        button.SetBinding(Button.CommandProperty, nameof(MyViewModel.MakeCommand));

        Content = new StackLayout
        {
            Children = { label, button }
        };

        BindingContext = viewModel;
    }
}
