//注: 在程序运行中往往有些要素类因为出错而无法删除，这时IDataset.Delete这个方法则无法成功，可以用轻量级的名称对象来完成这个任务。以下为C#+AE10源码。//删除要素类        public static bool DeleteFeatureDataset(IWorkspace ws, string name)        {            if (ws == null || string.IsNullOrEmpty(name))            {                ErrMsg = "工作空间或要素类名称不能为空!";                return false;            }            IFeatureDataset pFeaDataSet;            IEnumDatasetName pEnumDatasetName;            IFeatureWorkspace pFeaWorkspace;            IDatasetName pDatasetName;            try            {                pFeaWorkspace = ws as IFeatureWorkspace;                pEnumDatasetName = ws.get_DatasetNames(esriDatasetType.esriDTFeatureClass ^ esriDatasetType.esriDTFeatureDataset);                pEnumDatasetName.Reset();                pDatasetName = pEnumDatasetName.Next();                while (pDatasetName != null)                {                    if (pDatasetName.Type == esriDatasetType.esriDTFeatureDataset)                    {                        //如果是要素集，则对要素集内的要素类进行查找                        IEnumDatasetName pEnumFcName = (pDatasetName as IFeatureDatasetName).FeatureClassNames;                        IDatasetName pFcName = pEnumFcName.Next();                        while (pFcName != null)                        {                            if (pFcName.Name.IndexOf(name) >= 0)                            {                                DeleteByName(pFeaWorkspace, pFcName);                                return true;                            }                            pFcName = pEnumFcName.Next();                        }                    }                    else                    {                        if (pDatasetName.Name.IndexOf(name) >= 0)                        {                            DeleteByName(pFeaWorkspace, pDatasetName);                            return true;                        }                    }                    pDatasetName = pEnumDatasetName.Next();                }                return false;            }            catch (Exception ex)            {                ErrMsg = ex.Message;                return false;            }        }        //删除名称对象        public static void DeleteByName(IFeatureWorkspace pFeaWorkspace, IDatasetName pDatasetName)        {            IFeatureWorkspaceManage pWorkspaceManager = pFeaWorkspace as IFeatureWorkspaceManage;            pWorkspaceManager.DeleteByName(pDatasetName);        }
