如何从静态类改变UserControl属性？

public static class StaticClass
{
    public static void ChangeUserControlProperty(UserControl userControl)
    {
        userControl.Property = newValue;
    }
}

StaticClass.ChangeUserControlProperty(userControlInstance);

public static class StaticClass
{
    public static event Action<UserControl> UserControlPropertyChangeEvent;

    public static void RaiseUserControlPropertyChangeEvent(UserControl userControl)
    {
        UserControlPropertyChangeEvent?.Invoke(userControl);
    }
}

StaticClass.UserControlPropertyChangeEvent += (userControl) =>
{
    userControl.Property = newValue;
};

public static class StaticClass
{
    private static UserControl _userControl;

    public static UserControl UserControl
    {
        get { return _userControl; }
        set
        {
            _userControl = value;
            _userControl.Property = newValue;
        }
    }
}

StaticClass.UserControl = userControlInstance;
