c# - windows form design Ruined when connect to excel -


when connect excel file code (exactly when _conn.open();)

                _conn = new oledbconnection(_connectionstrting);                 _conn.open();                 datatable dt = _conn.getoledbschematable(oledbschemaguid.tables, null);                 string[] sheetnames = new string[dt.rows.count];                 int = 0;                  foreach (datarow row in dt.rows)                 {                     sheetnames[i] = row["table_name"].tostring();                     combobox2.items.add(sheetnames[i]);                     i++;                 }                  _conn.close();
