小编Gui*_*tel的帖子

我是C#的新手,实际上我正在创建一个PerspectiveCamera的子类

class VCamera : PerspectiveCamera
{

    private double m_AngleRadianX;
    private double m_AngleRadianZ;

    public VCamera()
    {
        m_AngleRadianX = 0.0;
        m_AngleRadianZ = 0.0;
        LookDirection = new Vector3D();          
    }
}

我的问题是我无法访问LookDirection,它是PerspectiveCamera的公共属性. http://msdn.microsoft.com/en-US/library/system.windows.media.media3d.perspectivecamera.aspx

是因为LookDirection继承自ProjectionCamera!？我不明白......

提前致谢.
