ArcGIS读取gdb内要素

            IWorkspaceFactory workspaceFactory = new FileGDBWorkspaceFactoryClass();
            IWorkspace workspace = workspaceFactory.OpenFromFile(@"F:/testData/test.gdb", 0);
            IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)workspace;

            IFeatureDataset featureDataset = featureWorkspace.OpenFeatureDataset("topo");

            IFeatureClass cxghFC = featureWorkspace.OpenFeatureClass("cxghph");

            IFeatureClass tdlyFC = featureWorkspace.OpenFeatureClass("tdly");

----------------------------------------------------------------------------------------------------------------------------------------------

读取数据集用的是 featureWorkspace.OpenFeatureDataset("topo");读取要素类用的是featureWorkspace.OpenFeatureClass("cxghph");那这个cxghph要素是test.gdb下的还是数据集topo下的呢？

在ArcMap里面手动导入的时候发现，如果test.gdb底下有名为 cxghph的要素类，那么topo要素集里面是无法再导入同名要素的。

同样，要素集内存在，gdb内是无法再导入同名要素，会提示 表已存在 。
