Recipe 10.14 Listing Tables in an Access Database

Problem

You need a list of all tables in your Access database.

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;

// . . .

// OLE DB

StringBuilder result = new StringBuilder( );

// Open the OLE DB connection.
