AE9.2下，用IBasicGeoprocessor.Intersect方法实现Shp数据之间的Intersect功能，大家恐怕都不陌生。最近做开发用到，但是数据时Geodatabase中的数据，因为其他原因，纠结了好一阵。不过还是被本人解决了，方法如下：
shp数据的相交核心代码如下：
IFeatureClassName pFeatClassName;
pFeatClassName = new FeatureClassNameClass();
pFeatClassName.FeatureType = esriFeatureType.esriFTSimple;
pFeatClassName.ShapeFieldName = "Shape";
pFeatClassName.ShapeType = pInputFeatClass.ShapeType;
//工作空间名称
IWorkspaceName pNewWSName;
pNewWSName = new WorkspaceNameClass();
pNewWSName.WorkspaceFactoryProgID = "esriDataSourcesFile.ShapefileWorkspaceFactory";
pNewWSName.PathName = System.Windows.Forms.Application.StartupPath + @"\temp";
//数据集名称
IDatasetName pDatasetName;
pDatasetName = pFeatClassName as IDatasetName;
pDatasetName.Name = pInputFeatLayer.Name + "_Intersect" + DateTime.Now.ToString("yyyy-MM-dd_HH-mm-ss");
pDatasetName.WorkspaceName = pNewWSName;
double tol = 0.1;
//几何处理
IBasicGeoprocessor pBGP;
pBGP = new BasicGeoprocessorClass();
pBGP.SpatialReference = axMapControl1.SpatialReference;
IFeatureClass pOutputFeatClass;
pOutputFeatClass = pBGP.Intersect(pInputTable, false, pOverlayTable, false, tol, pFeatClassName);
注意标红的代码，下面主要修改就是这两行：
为了实现Geodatabase下数据的相交功能，把这两行改为：
pNewWSName.WorkspaceFactoryProgID = "esriDataSourcesFile.AccessWorkspaceFactory";
pNewWSName.PathName = "E:\\PersonDatabase.mdb";
实验一下，成功。其中要注意的是，数据库下，图层的名字有限制，所以，最好不要像Shp的那么长。
