Export geometry to file

Guglielmo_Cordasco

Hi, I'm using a SOE and I would like to export a geometry to file in order to share it.
I tried with ExportToESRIShape (like in this example) but saving the output buffer in a file I didn't obtain a known format (e.g. shp or zip).
Anyone knows about another method? or an ExportToESRIShape  example to export to file?

Thanks in advance,
Guglielmo.

In help you need see class that implement the interface IFeatureClassName

You can write similar code:

IMapServer mapServer = (IMapServer)serverObjectHelper.ServerObject;
            string mapName = mapServer.DefaultMapName;
            IMapServerDataAccess dataAccess = (IMapServerDataAccess)mapServer;
            IFeatureClass sourceFeatureClass = (IFeatureClass)dataAccess.GetDataSource(mapName, 0);

            IDataset sourceDataSet = (IDataset)sourceFeatureClass;
            IWorkspace sourceWorkspace = sourceDataSet.Workspace;

            IFeatureDataConverter featureDataConverter = new FeatureDataConverterClass();
            IWorkspaceFactory targetWorkspaceFactory = new ShapefileWorkspaceFactory();
            IWorkspace targetWorkspace = targetWorkspaceFactory.OpenFromFile($@"c:\temp", 0);
            IDataset targetWorkspaceDataset = (IDataset)targetWorkspace;
            IName targetWorkspaceDatasetName = targetWorkspaceDataset.FullName;
            IWorkspaceName targetWorkspaceName = (IWorkspaceName)targetWorkspaceDatasetName;
            IFeatureClassName shpFeatureClassName = new FeatureQueryNameClass();
            IDatasetName shpDatasetName = (IDatasetName)shpFeatureClassName;
            shpDatasetName.WorkspaceName = targetWorkspaceName;
            shpDatasetName.Name = $"Test_{Guid.NewGuid()}";

            int shapeFieldPosition = sourceFeatureClass.FindField(sourceFeatureClass.ShapeFieldName);
            IFields inputFields = sourceFeatureClass.Fields;
            IField shapeField = inputFields.get_Field(shapeFieldPosition);

            IGeometryDef geometryDef = (IGeometryDef)((IClone)shapeField.GeometryDef).Clone();

            IFields outFields = (IFields)((IClone)sourceFeatureClass.Fields).Clone();

            featureDataConverter.ConvertFeatureClass((IFeatureClassName)sourceDataSet.FullName, null, null, shpFeatureClassName, geometryDef, outFields, "", 1000, 0);
