GeoMedia C# code snippet to get the warehouse connection's table list

It is useful to programmatically retrieve the list of tables in a GeoMedia warehouse via the connection object. The GeoMedia MetadataService can be called upon to generate the list in a String array. The following C# code snippet shows how this can be done.

The connection object is passed in to the GetTableList method and returns an ArrayList of table names.

using GeoMedia = Intergraph.GeoMedia.GeoMedia;
using PCSS = Intergraph.GeoMedia.PCSS;
using PBasic = Intergraph.GeoMedia.PBasic;
using GDO = Intergraph.GeoMedia.GDO;
using PClient = Intergraph.GeoMedia.PClient;
using PService = Intergraph.GeoMedia.PService;
using GMService = Intergraph.GeoMedia.GMService;
//...etc...
private ArrayList GetTableList(PClient.Connection conn)
{
String[] list = null;
ArrayList tables = new ArrayList();
object oConn = (object)conn;
int mask = 0;
object vTables = null;
GMService.MetadataService metadataSvc = null;

//Create an instance of the GeoMedia MetadataService
metadataSvc = new GMService.MetadataService();
//Pass in the connection object to the MetadataService
metadataSvc.set_Connection(ref oConn);
//Get the connection's list of tables and put them into the vTables array
metadataSvc.GetTables(ref mask, ref vTables);

//copy the table list into an ArrayList and return to the calling function
list = (String [])vTables;
for (int i = 0; i < list.Length; i++)
tables.Add(list[i].ToUpper());
return tables;
}
