ArcGIS AddIN开发:如何调用ArcMap中的选择工作空间的窗体

示例代码如下:

 public static IWorkspaceName BrowseWorkspace(int hwnd,out IWorkspace ws)

        {

            IGxObjectFilterCollection ipFilters = new GxDialogClass();

            //IGxObjectFilter ipFilter1 = new GxFilterFeatureDatasetsClass();  //要素数据集 ,导出时,IFeatureClassConverter对象无法写入Dataset中,此处隐藏掉

            //ipFilters.AddFilter(ipFilter1,false);

            IGxObjectFilter ifilt2 = new GxFilterWorkspacesClass();  //数据库工作空间,此类比较含糊,不知道具体指啥

            ipFilters.AddFilter(ifilt2,false);

            IGxObjectFilter ipFilter3 = new GxFilterFileFolderClass();  //文件工作空间

            ipFilters.AddFilter(ipFilter3,false);

            IGxDialog pGDialog = (IGxDialog)ipFilters;

            pGDialog.RememberLocation = true;

            pGDialog.Title = "请选择工作空间";

            pGDialog.AllowMultiSelect = false;

            IEnumGxObject pResultEnum = null;

            //IWorkspace ws = null;

            ws = null;

            IWorkspaceName wsn = null;

            if (pGDialog.DoModalOpen(hwnd, out pResultEnum) && pResultEnum != null)

            {

                IGxObject gxObj = pResultEnum.Next();

                if (gxObj is IGxDatabase)

                {

                    IGxDatabase gxDB = gxObj as IGxDatabase;

                    if (gxDB != null)

                    {

                        ws = gxDB.Workspace;

                        wsn = gxDB.WorkspaceName;

                    }

                }

                else if (gxObj is IGxFolder)

                {

                    //Todo: figure out how to decide which workspace to get for

                    // a particular folder (shapefile, raster etc.)

                    //IEnumName enumName = ((IGxFolder)gxObj).FileSystemWorkspaceNames;

                    // for now just assume we want a shapefile ...

                    IWorkspaceFactory wsf = new ESRI.ArcGIS.DataSourcesFile.ShapefileWorkspaceFactoryClass();

                    ws = wsf.OpenFromFile(((IGxFile)gxObj).Path, hwnd);

                    IDataset pOutDataset = ws as IDataset;

                    wsn = pOutDataset.FullName as IWorkspaceName;

                }

                else if (gxObj is IGxDataset)

                {

                    //如果是数据集工作空间

                    IGxDataset gxDs = gxObj as IGxDataset;

                    if (gxDs != null)

                    {

                        ws = gxDs.Dataset.Workspace;

                        wsn = gxDs.DatasetName.WorkspaceName;

                    }

                }

                Marshal.FinalReleaseComObject(pResultEnum);

            }

            pGDialog.InternalCatalog.Close();

            Marshal.FinalReleaseComObject(pGDialog);

            return wsn;

        }

上述代码可以拓展为:调用ArcMap的添加图层窗口等
