To get the tables:
OleDbConnection cn = new OleDbConnection(connectionString);
...
DataTable schemaTable = cn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables,
new object[] {null, null, null, "TABLE"});
//schemaTable now contains one row for each table in the database
To get the fields:
DataTable schemaTable = cn.GetOleDbSchemaTable(OleDbSchemaGuid.Columns,
new Object[]{null, null, tableName});
//schemaTable now contains one row for each column in tableName

Thanks for using Microsoft Newsgroup Support Service, this is Colbert Zhou
[MSFT] and I will be working on this issue with you.
The first approach, we can use GetOleDbSchemaTable method to get Access
Database schema. The following codes show how to do it,
string connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data
Source=DatabaseFile.mdb";
OleDbConnection oleDb = new OleDbConnection(connectionString);
oleDb.Open();
object[] arrRestrict;
arrRestrict = new object[] { null, null, "Customers", null };
DataTable tblDbSchema = oleDb.GetOleDbSchemaTable(OleDbSchemaGuid.Columns,
arrRestrict);
oleDb.Close();
For more detailed information, please refer the following articles and
documents

Another option is using ADOX to achieve this objective. ADOX is the object
model of Microsoft Office Acces. We can view, create, and modify the
structure of Access databases by using ADOX objects, methods, and
properties.
Please read the document to know how to list all tables in the Access
DataBase using ADOX,

If you have any future questions or concerns, please feel free to let me
know. And I will do a follow up support.
Have a nice day, Peter!
