ReactiveUI 6.0 and WinForms binding

现在ReactiveUI 6.0已经发布了，我有一个问题要问社区:绑定ReactiveObject(s)和Windows Form(s)的最好或最有效的方法是什么

到目前为止我写的是:

我的模型

namespace WindowsFormsApplication1
{
    #region
    using System;
    using System.Reactive.Linq;
    using ReactiveUI;
    #endregion
    public class ClockModel : ReactiveObject
    {
        #region Fields
        private DateTime currentDateTime;
        #endregion
        #region Constructors and Destructors
        public ClockModel() { Observable.Interval(TimeSpan.FromSeconds(1)).Subscribe(s => this.CurrentDateTime = DateTime.Now); }
        #endregion
        #region Public Properties
        public DateTime CurrentDateTime
        {
            get { return currentDateTime; }
            set { this.RaiseAndSetIfChanged(ref currentDateTime, value); }
        }
        #endregion
    }
}

我唯一的形式

using System.Windows.Forms;
namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        readonly ClockModel model = new ClockModel();
        public Form1()
        {
            InitializeComponent();
            this.label1.DataBindings.Add("Text", model, "CurrentDateTime");
        }
    }
}

它确实可以工作，但是我不喜欢用字符串名来引用两边的属性。有没有更好的方法来做到这一点?

更新1

给定扩展名:

public class NameOf<T>
{
    public static string Property<TProp>(Expression<Func<T, TProp>> expression)
    {
        var body = expression.Body as MemberExpression;
        if (body == null)
            throw new ArgumentException("'expression' should be a member expression");
        return body.Member.Name;
    }
}

这种形式比前一种更可取吗?

this.label1.DataBindings.Add(NameOf<Form1>.Property(e => e.label1.Text), model, NameOf<ClockModel>.Property(p => p.CurrentDateTime));

更新2

另一个扩展:

public static class Extensions
{
    public static string GetPropertyName<T,TProp>(this T obj, Expression<Func<T, TProp>> expression)
    {
        var body = expression.Body as MemberExpression;
        if (body == null)
            throw new ArgumentException("'expression' should be a member expression");
        return body.Member.Name;
    }
}

现在我可以使用:

this.label1.DataBindings.Add(this.GetPropertyName(e => e.label1.Text), model, model.GetPropertyName(p => p.CurrentDateTime));

或:

this.label2.DataBindings.Add(this.label2.GetPropertyName(e => e.Text), model, model.GetPropertyName(p => p.Ticks));

我开始喜欢这个方法了，但是其他人怎么看这三种方法呢?

从技术上讲，表单变成了视图和控制器或呈现器，而模型仍然是分开的，并且不知道它的消费者。这是首选的方法吗?

更新3

这可能会导致一些纯粹主义者轻微的心脏病发作……基于Paul Betts的建议:

namespace WindowsFormsApplication1
{
    #region
    using System.Windows.Forms;
    using ReactiveUI;
    #endregion
    public partial class Form1 : Form, IViewFor<ClockModel>
    {
        #region Constructors and Destructors
        public Form1()
        {
            InitializeComponent();
            this.ViewModel = new ClockModel();
            this.Bind(ViewModel, vm => vm.CurrentDateTime, v => v.label1.Text);
            this.Bind(ViewModel, vm => vm.Ticks, v => v.label2.Text);
        }
        #endregion
        #region Public Properties
        public ClockModel ViewModel { get; set; }
        #endregion
        #region Explicit Interface Properties
        object IViewFor.ViewModel
        {
            get { return ViewModel; }
            set { ViewModel = value as ClockModel; }
        }
        #endregion
    }
}

有趣的行为变化:更新3之前，时间以秒为单位显示。我只能认为这是由于第三种方法中使用了默认的ReactiveUI转换器。我得多了解一些。

public class DateTimeStringConverter : IBindingTypeConverter
{
    public int GetAffinityForObjects(Type fromType, Type toType) { return 1; }
    public bool TryConvert(object @from, Type toType, object conversionHint, out object result) { 
        result = ((DateTime)@from).ToString("F");
        return true;
    }
}

我喜欢这种方法的优雅。

还有其他意见吗?
