本文介绍了一种使用C#代码在ArcGIS中加载CAD文件的方法。通过创建对话框选择CAD文件，然后利用ArcGIS的CADWorkspaceFactory和CadDrawingNameClass等组件，实现了CAD文件的读取与地图图层的添加。

using (openFileDialog = new OpenFileDialog())
{
openFileDialog.Title = "打开CAD文件";
openFileDialog.Filter = "(*.dwg)|*.dwg";
if (openFileDialog.ShowDialog() == DialogResult.OK)
{
openFullPath = openFileDialog.FileName;
fileName = System.IO.Path.GetFileName(openFullPath);
openPath = System.IO.Path.GetDirectoryName(openFullPath);
if (openPath == null) return;
IWorkspaceName pWorkspaceName = new WorkspaceNameClass();
pWorkspaceName.WorkspaceFactoryProgID = "esriDataSourcesFile.CadWorkspaceFactory";
pWorkspaceName.PathName = openPath;
//Create a CadDrawingName object
IDatasetName pDatasetName = new CadDrawingNameClass();
pDatasetName.Name = fileName;
pDatasetName.WorkspaceName = pWorkspaceName;
//Open the CAD drawing
IName pName = (IName)pDatasetName;
ICadDrawingDataset pCadDrawingDataset = (ICadDrawingDataset)pName.Open();
if (pCadDrawingDataset == null) return;
ICadLayer pCadLayer = new CadLayerClass();
pCadLayer.CadDrawingDataset = pCadDrawingDataset;
pCadLayer.Name = fileName;
axMapControl1.AddLayer(pCadLayer);
}
