Shape文件导入featuredataset要素数据集

大体思路就是：

1.获取shape文件的空间参考，在mdb中根据该空间参考新建要素数据集：

  private void PRV_CreatFeatureDataset(string IN_FeatureDataSetName,string IN_ShapePath)        {            string Temp_Direction = System.IO.Path.GetDirectoryName(IN_ShapePath);//Shp文件的目录            string Getname = System.IO.Path.GetFileNameWithoutExtension(IN_ShapePath);//Shp文件的文件名            IWorkspaceFactory Temp_MDBWorkFactory = new AccessWorkspaceFactory();            IFeatureWorkspace Temp_MDBWorkspace = Temp_MDBWorkFactory.OpenFromFile(S_MDBFile, 0) as IFeatureWorkspace;            IWorkspaceFactory Temp_ShapeWorkFactory = new ShapefileWorkspaceFactory();            IFeatureWorkspace Temp_ShapeWorkspace = Temp_ShapeWorkFactory.OpenFromFile(Temp_Direction, 0) as IFeatureWorkspace;            IFeatureClass Temp_ShapeFeatureClass = Temp_ShapeWorkspace.OpenFeatureClass(Getname);//获取shp文件            ISpatialReference SP_SpatialRefer = (Temp_ShapeFeatureClass as IGeoDataset).SpatialReference;//获取空间投影            Temp_MDBWorkspace.CreateFeatureDataset(IN_FeatureDataSetName, SP_SpatialRefer);//在MDB中创建要素数据集            FDS_Featuredataset = Temp_MDBWorkspace.OpenFeatureDataset(IN_FeatureDataSetName);//获取返回的要素数据集        }

2.将shape文件插入该要素数据集：

        private void PRV_AddFeatureClass(string IN_ShapePath)        {            string Temp_Direction = System.IO.Path.GetDirectoryName(IN_ShapePath);//该Shp文件的目录            string Temp_Name = System.IO.Path.GetFileNameWithoutExtension(IN_ShapePath);//该Shp文件的名称            IWorkspaceFactory Temp_ShapeWorkFactory = new ShapefileWorkspaceFactory();            IFeatureWorkspace Temp_ShapeWorkspace = Temp_ShapeWorkFactory.OpenFromFile(Temp_Direction,0) as IFeatureWorkspace;            IWorkspaceFactory Temp_AccessWorkFactory = new AccessWorkspaceFactory();            IFeatureWorkspace Temp_Workspace = Temp_AccessWorkFactory.OpenFromFile(S_MDBFile, 0) as IFeatureWorkspace;            IFeatureClass Temp_FeatureClass = Temp_ShapeWorkspace.OpenFeatureClass(Temp_Name);            FeatureClassToFeatureClass Temp_FCToFC = new FeatureClassToFeatureClass(IN_ShapePath, S_MDBFile + "\\" + FDS_Featuredataset.Name, Temp_Name + "__");//将Shp文件导入要素数据集            GP_Tool.Execute(Temp_FCToFC,null);            Console.WriteLine("完成");        }

其中：GP_Tool是一个GP工具运行器

Geoprocessor GP_Tool = new Geoprocessor();//GP运行工具

S_MDBFile是MDB文件的路径

FDS_FeatureDataset是上文生成的要素数据集
