如何判断一个featureclass是否存在

IEnumDatasetName pEnumDatasetName = pWorkspace.get_DatasetNames(esriDatasetType.esriDTFeatureClass);

            pEnumDatasetName.Reset();

            IDatasetName pDatasetName = pEnumDatasetName.Next();

            bool b_Find = false;

            while (pDatasetName != null)

                {

                    if (pDatasetName.Name == strName)

                    {

                        b_Find = true;

                        break;

                    }

                    pDatasetName = pEnumDatasetName.Next();

                }

当然还有FeatureDataset中也要检查，（esriDatasetType.esriDTFeatureDataset），要用到FeatureDatasetName.SubsetNames，具体查看帮助文档
