NotImplementedException: OleDb is not implemented

Hello

I m trying to open a DBF file with OleDbConnection , exported from QGis in unity using the code bellow :

  string filepath ="C:\\Users\\thano\\Documents\\Interreg\\Assets\\GIS_Data";
 
 void start {
 
  OleDbConnection ccc = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filepath + ";Extended Properties=dBASE IV;");
         ccc.Open();
         OleDbCommand cmd1 = new OleDbCommand("Select * From " + filepath + "ydr_diktyo_loupas_wgs84.dbf", ccc);
         OleDbDataReader dr1 = cmd1.ExecuteReader();
         if (dr1.HasRows)
         {
             DataTable dt1 = new DataTable();
             dt1.Load(dr1);
         }
         ccc.Close();
 
 
 }

 

but i get this error :

NotImplementedException: OleDb is not implemented. System.Data.OleDb.OleDbConnection..ctor (System.String connectionString) (at :0) (wrapper remoting-invoke-with-check) System.Data.OleDb.OleDbConnection..ctor(string) DBF_importer.Start () (at Assets/GIS_Data/DBF_importer.cs:45)
