private void button1_click(object sender, eventargs e) {     system.globalization.cultureinfo oldci = system.threading.thread.currentthread.currentculture;     system.threading.thread.currentthread.currentculture = new system.globalization.cultureinfo("en-us");      // creating excel application     microsoft.office.interop.excel._application app = new microsoft.office.interop.excel.application();     system.threading.thread.currentthread.currentculture = oldci;      // creating new workbook within excel application     microsoft.office.interop.excel._workbook workbook = app.workbooks.add(type.missing);      // creating new excel sheet in workbook     microsoft.office.interop.excel._worksheet worksheet = null;      // see excel sheet behind program     //funny     app.visible = true;      // reference of first sheet. default name sheet1.     // store reference worksheet     try     {         // fixed:(microsoft.office.interop.excel.worksheet)         worksheet = (microsoft.office.interop.excel.worksheet)workbook.sheets["sheet1"];         worksheet = (microsoft.office.interop.excel.worksheet)workbook.activesheet;          // changing name of active sheet         worksheet.name = "exported ketoan";          // storing header part in excel         (int = 1; < dgdata.columns.count + 1; i++)         {             worksheet.cells[1, i] = dgdata.columns[i - 1].headertext;         }          // storing each row , column value excel sheet         (int = 0; < dgdata.rows.count - 1; i++)         {             (int j = 0; j < dgdata.columns.count; j++)             {                 worksheet.cells[i + 2, j + 1] = dgdata.rows[i].cells[j].value.tostring();             }         }          // save application         string filename = string.empty;         savefiledialog savefileexcel = new savefiledialog();          savefileexcel.filter = "excel files |*.xls|all files (*.*)|*.*";         savefileexcel.filterindex = 2;         savefileexcel.restoredirectory = true;          if (savefileexcel.showdialog() == dialogresult.ok)         {             filename = savefileexcel.filename;              //fixed-old code: 11 para->add 1:type.missing             workbook.saveas(filename, type.missing, type.missing, type.missing, type.missing, type.missing, microsoft.office.interop.excel.xlsaveasaccessmode.xlexclusive, type.missing, type.missing, type.missing, type.missing, type.missing);         }         else             return;          // exit application         //app.quit();     }     catch (system.exception ex)     {      }         {         app.quit();         workbook = null;         app = null;     } }

your code works fine on office 2007 + vs 2010. versions using? mayby have choosen wrong version of interop refernece: office 2007 = 12.0.0.0, office 2010 = 14.0.0.0
