添加控件DynWorldDraw事件，在事件中响应自定义实体的动态绘制，C#代码实现如下：

private void axMxDrawX1_DynWorldDraw(object sender, AxMxDrawXLib._DMxDrawXEvents_DynWorldDrawEvent e)
{
    // 得到当前动态绘制数据。
    MxDrawCustomEntity pCustomEntity = (MxDrawCustomEntity)e.pData;
    String sGuid = pCustomEntity.Guid;
    e.pRet = 0;
 
    // 得到绘制对象.
    MxDrawWorldDraw pWorldDraw = (MxDrawWorldDraw)e.pWorldDraw;
    
    // 得到当前鼠标点.
    MxDrawPoint curPt = new MxDrawPoint();
    curPt.x = e.dX;
    curPt.y = e.dY;
 
    if (sGuid == "DrawCustEntity")
    {
        // 动态绘制DrawCustEntity
        MyDrawMline(pWorldDraw, pCustomEntity, curPt);
    }
}
