Access “Compact and Repair” programmatically

Question

Is it possible to \"compact and repair\" an Access database programmatically somehow (using ADOX, using OleDbConnection etc.)?

Answer 1

This solution works with the Access 2010 Database Engine:

Required reference:

Microsoft.Office.interop.access.dao

Code:

public void CompactDb(
    string sourceFilePath, string destFilePath, string password)
{
    var dbEngine = new Microsoft.Office.Interop.Access.Dao.DBEngine();

    dbEngine.CompactDatabase(sourceFilePath, destFilePath,
        ";pwd=" + password, null, ";pwd=" + password);
}

(The sourceFilePath and destFilePath should not be the same!)

CompactDatabase method parameters (from reflection):

void CompactDatabase(
    string SrcName, string DstName,
    object DstLocale = Type.Missing,
    object Options = Type.Missing,
    object SrcLocale = Type.Missing);

Make sure you run it under the same platform as the AccessDatabaseEngine (or Office) you installed (x86/x64).
