无法访问asp.net中的.DBF文件

Question

我无法在asp.net中读取.dbf文件。

错误：外部表格不符合预期格式。

 1)  Using OLEDB

      OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\\VisualFoxproDB;Extended Properties=dBASE 5.0;");
                        OleDbCommand command = new OleDbCommand("SELECT ID,NAME FROM table.dbf", conn);
                        conn.Open();
                        DataTable dt = new DataTable();
                        dt.Load(command.ExecuteReader());
                        gv1.DataSource = dt;
                        gv1.DataBind();
                        conn.Close();    

2. Using ODBC   

     OdbcConnection conn = new OdbcConnection("Driver={Driver do Microsoft dBase (*.dbf)};DriverId=277;SourceType=DBF;SourceDB=D:\\VisualFoxproDB\\;Exclusive=No");     
                            conn.Open();
                            string strQuery = "SELECT * FROM D:\\VisualFoxproDB\\test.dbf";
                            System.Data.Odbc.OdbcDataAdapter adapter = new System.Data.Odbc.OdbcDataAdapter(strQuery, conn);
                            System.Data.DataSet ds = new System.Data.DataSet();
                            adapter.Fill(ds);
                            return ds.Tables[0];
