mcSelectionSetCrossing方式：只要实体对象与给的范围相交，并不需要完全在范围也能得到。

c#中使用如下：

private void SelectCross()
{
    //创建选择集对象
    MxDrawSelectionSet ss = new MxDrawSelectionSet();
    //创建过滤对象
    MxDrawResbuf spFilte = new MxDrawResbuf();
 
    MxDrawUtility mxUtility = new MxDrawUtility();
    //点取范围左上角位置
    MxDrawPoint point = (MxDrawPoint)(mxUtility.GetPoint(null, "点取范围左上角位置..."));
    //点取范围左下角位置
    MxDrawPoint point1 = (MxDrawPoint)(mxUtility.GetPoint(null, "点取范围右下角位置..."));
 
    //选取跨范围的实体
    ss.Select(MCAD_McSelect.mcSelectionSetCrossing, point, point1, spFilte);
    for (var i = 0; i < ss.Count; i++)
    {
        var ent = ss.Item(i);
        MessageBox.Show(ent.ObjectName);
    }
}
