如何在WPF中取消关联触摸和鼠标事件

行

fe.IsManipulationEnable = true;

在构造函数中已经完成了技巧：

public class Behavior<T> where T : FrameworkElement
{
    public static bool IsManipulating = false;
    protected T fe;
    private bool enable;
    public bool Enable
    {
        get
        {
            return enable;
        }
        set
        {
            bool changed = false;
            if (enable != value)
            {
                changed = true;
            }
            enable = value;
            if (changed)
            {
                if (enable)
                {
                    Enable_Partial();
                }
                else
                {
                    Disable_Partial();
                }
            }
        }
    }

    public Behavior(T _fe)
    {
        fe = _fe;
        fe.IsManipulationEnabled = true;
        enable = true;
    }
    protected virtual void Enable_Partial()
    {
    }
    protected virtual void Disable_Partial()
    {
    }
}
