Question

Access can open DBF (dBase) files, but instead of physically converting the data into MDB format, it has the ability to link to the DBF table itself. This way the DBF is ‘linked’ to the MDB.

Is it possible to attach a DBF file in such manner using C#?

Edit: I would like to use Jet and avoid using MS Access directly.

Perhaps this code from How to quickly copy tables from an ODBC source to MS Access within a C# project might help:

The VB function you’ll need to put into MS Access is quite simple, and basically calls the TransferDatabase method by passing it a DSN (pointing to the source database), a source table name and target table name. The code is as follows:

Public Function Import(dsnName As String, sourceTableName As String, targetTableName As String) ‘ if the table already existsm, delete it.    On Error GoTo CopyTable    DoCmd.DeleteObject acTable, targetTableName CopyTable:    DoCmd.TransferDatabase _    acImport, _    'ODBC Database', _    'ODBC;DSN=' + dsnName, _    acTable, _    sourceTableName, _    targetTableName End Function 

Changing the VBA to read acLink rather than acImport should allow linking.

And then the C# code:

object accessObject = null; try {    accessObject = Activator.CreateInstance(Type.GetTypeFromProgID('Access.Application'));     accessObject.GetType().InvokeMember(       'OpenCurrentDatabase',       System.Reflection.BindingFlags.Default  System.Reflection.BindingFlags.InvokeMethod,       null,       accessObject,       new Object[] { 'AccessDbase.mdb' });     accessObject.GetType().InvokeMember(       'Run',       System.Reflection.BindingFlags.Default  System.Reflection.BindingFlags.InvokeMethod,       null,       accessObject,       new Object[] { 'Import', 'DSN Name', 'Source table name', 'Target table name' });     accessObject.GetType().InvokeMember(       'CloseCurrentDatabase',       System.Reflection.BindingFlags.Default  System.Reflection.BindingFlags.InvokeMethod,       null,       accessObject,       null);     MessageBox.Show('Copy succeeded.'); } catch (Exception ex) {    string message = ex.Message;    while (ex.InnerException != null)    {       ex = ex.InnerException;       message += '\r\n----\r\n' + ex.Message;    }    MessageBox.Show(message); } finally {    if (accessObject != null)    {       System.Runtime.InteropServices.Marshal.ReleaseComObject(accessObject);       accessObject = null;    } } 

Edit re comments

I cannot help with c#, but here is some VBScript that links a table from one MDB to another.

strLinkFile = 'C:\Docs\Link.mdb' strAccessFile = 'C:\Docs\LTD.mdb'  'Create Link... ' Set cn = CreateObject('ADODB.Connection') cn.Open 'Provider=Microsoft.Jet.OLEDB.4.0;' & _        'Data Source=' & strAccessFile & ';' & _        'Persist Security Info=False'  Set adoCat = CreateObject('ADOX.Catalog') Set adoCat.ActiveConnection = cn  Set adoTbl = CreateObject('ADOX.Table')  Set adoTbl.ParentCatalog = adoCat adoTbl.Name = 'LinkTable'  adoTbl.properties('Jet OLEDB:Link Datasource') = strLinkFile adoTbl.properties('Jet OLEDB:Link Provider String') = 'MS Access' adoTbl.properties('Jet OLEDB:Remote Table Name') = 'Table1' adoTbl.properties('Jet OLEDB:Create Link') = True  'Append the table to the tables collection ' adoCat.Tables.Append adoTbl
