以下代码遍历一个Access数据库statescounties，它是一个工作空间对象
IWorkspaceFactory pAccessWorkspaceFactory;
pAccessWorkspaceFactory = new AccessWorkspaceFactoryClass();
//打开工作空间
IWorkspace pWorkspace;
pWorkspace = pAccessWorkspaceFactory.OpenFromFile(@"D:\temp\New Personal Geodatabase.mdb", 0);
IEnumDataset pEnumDataset;
pEnumDataset = pWorkspace.get_Datasets(esriDatasetType.esriDTAny);
IDataset pDataset;
pEnumDataset.Reset();
pDataset = pEnumDataset.Next();
while (pDataset != null)
{
MessageBox.Show(pDataset.Name);
pDataset = pEnumDataset.Next();
}
}
错误异常为：未处理 System.Runtime.InteropServices.COMException
