C# 如何将对象绑定到动态创建的标签？

我正在尝试绑定，但似乎不起作用：/

我的代码：

    void Binding(velocity Object, Label Output, string Field)
    {
        Binding newBinding = new Binding();
        newBinding.Source = Object;
        newBinding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
        newBinding.Path = new PropertyPath(Field);
        Output.SetBinding(Label.ContentProperty, newBinding);
    }
            Binding(newProjectile.CurrentVelocity, lbl_CurrentVelOutput, "Magnitude"); // how i call it

非常感谢！ 编辑：我没有得到错误，只是输出上的标签没有改变

编辑：我试着寻找如何实现INotifyChange接口，得到了如下结果

public class velocity : INotifyPropertyChanged
  {
    public event PropertyChangedEventHandler PropertyChanged;
    protected void OnPropertyChanged(string name)
    {
        PropertyChangedEventHandler Handler = PropertyChanged;
        if (Handler != null)
        {
            Handler(this, new PropertyChangedEventArgs(name));
        }
    }
    public double Velocity
    {
        get { return Magnitude; }
        set
        {
            Magnitude = value;
            OnPropertyChanged("10");
        }
    }

但是我不知道我在做什么。

您的绑定应该工作得很好，但是如果您希望对magnize属性的更改自动显示在您的视图中，那么您必须让WPF知道这些更改。这就是INotifyProperty接口的用武之地，因为它允许您的代码让WPF知道哪些属性已更改：

// In C#, the common convention is to give classes CamelCased names:
public class Velocity : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;
    protected void OnPropertyChanged(string propertyName)
    {
        // Local variables and method arguments are also camelCased,
        // but they start with a lower-case character:
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
            handler(this, new PropertyChangedEventArgs(propertyName));
    }

    // Properties with default getters and setters automatically get a 'backing field',
    // but we can't use that because we need to call OnPropertyChanged, so we'll have to
    // manually write out things. Normally, you'd give the backing field a name similar
    // to the property, so it's obvious that they belong together:
    private double _magnitude;
    public double Magnitude
    {
        get { return _magnitude; }
        set
        {
            _magnitude = value;

            // Here, you need to pass in the *name* of the property that's being changed,
            // so WPF knows which views it needs to update (WPF can fetch the new value
            // by itself):
            OnPropertyChanged("Magnitude");
        }
    }
}

您的标签绑定看起来如何？有没有可能有更多的代码？对象和字段是什么？添加了参数字段字段字段字段或属性的名称？绑定仅适用于属性。在.CurrentVelocity中有一个属性表示幅值。我做得对吗？
