arcgis server 9.3 ADF开发 CAD文件本地动态加载到graphicslayer中未成功案例

这种方法调试很久没成功，记录下来看看有没有人已经突破了

1。按钮click方法里：

　　 ReadCADShp clsCAD = new ReadCADShp();
clsCAD.loadCAD(Map1, @"D:\data\需测量合图40坐标.dwg");
//Map1.Extent = env;
MapResourceManager1.Refresh();
Toc1.Refresh();
Map1.Refresh();

　　2。clsCAD类里：

　　

using ESRI.ArcGIS.Geodatabase;
using ESRI.ArcGIS.DataSourcesFile;
using ESRI.ArcGIS.Carto;
using ESRI.ArcGIS.ADF.Web.DataSources.ArcGISServer;
using System.Data;

//
