Solution Use the GetOLEDBSchemaTable method of the OleDbConnection class or use ADOX through COM interop. The first technique uses the GetOLEDBSchemaTable method to return schema information about user tables. These results are then displayed. For the second technique you ll need a reference to the Primary Interop Assembly PIA for ADO provided in the file ADODB.DLL select adodb from the .NET tab in Visual Studio .NET s Add Reference Dialog. You ll also need a reference to Microsoft ADO Ext. 2.7 for DDL and Security from the COM tab in Visual Studio .NET s Add Reference Dialog. The second technique creates an ADOX Catalog object through COM interop. The Tables property of this object accesses the collection of tables from which the name and other information are displayed. The C code is shown in Example 10-14. Example 10-14. File ListAccessTablesForm.cs Namespaces variables and constants using System using System.Configuration using System.Text using System.Data using System.Data.OleDb . . .
