//在MDB里创建空表 白明雅 2019-03-29
                        IFields fields = null;
                        GeoDBAPI.CreateFields(inFc.FeatureClass.Fields, out fields);
                        IFeatureDataset dataset = inFc.FeatureClass.FeatureDataset;
                        dataset.CreateFeatureClass(System.IO.Path.GetFileNameWithoutExtension(pOutFeatureClass), fields, null, null, esriFeatureType.esriFTSimple, "SHAPE", "");

//打开创建的要数集
                        pFeatureLayer.FeatureClass = workspaceAPI.OpenFeatureClass(System.IO.Path.GetFileNameWithoutExtension(pOutFeatureClass)).FeatureClass;
