c# - Does NPOI have support to .xlsx format? -


will npoi dll recognize .xlsx file?

currently i'm using npoi 1.2.5 version dll microsoft excel 97-2003, need access excel sheets of extension .xlsx also.

will npoi support above?

code snippet: 

static void main(string[] args) {     xssfworkbook xssfwb;      using(filestream file=new filestream(             @"c:\users\347702\desktop\hello.xlsx",             filemode.open, fileaccess.read)) {         xssfwb=new xssfworkbook(file);     }      isheet sheet=xssfwb.getsheet("sheet1");     sheet.getrow(1048576);     console.writeline(sheet.getrow(1048576).getcell(0).stringcellvalue); }

yes does. npoi 2.0 beta works. here's sample code started:

class program { static xssfworkbook hssfworkbook; static dataset dataset1 = new dataset();  static void main(string[] args) {     initializeworkbook(@"e:\docs\hourswidget_rtm.xlsx");     xlsxtodt();      displaydata(dataset1.tables[0]);      console.readline(); }  static void initializeworkbook(string path) {     using (filestream file = new filestream(path, filemode.open, fileaccess.read))     {         hssfworkbook = new xssfworkbook(file);     } }  static void xlsxtodt() {     datatable dt = new datatable();     isheet sheet = hssfworkbook.getsheetat(1);     irow headerrow = sheet.getrow(0);     ienumerator rows = sheet.getrowenumerator();      int colcount = headerrow.lastcellnum;     int rowcount = sheet.lastrownum;      (int c = 0; c < colcount; c++)     {          dt.columns.add(headerrow.getcell(c).tostring());     }      bool skipreadingheaderrow = rows.movenext();     while (rows.movenext())     {         irow row = (xssfrow)rows.current;         datarow dr = dt.newrow();          (int = 0; < colcount; i++)         {             icell cell = row.getcell(i);              if (cell != null)             {                 dr[i] = cell.tostring();             }         }         dt.rows.add(dr);     }      hssfworkbook = null;     sheet = null;     dataset1.tables.add(dt); }  static void displaydata(datatable table) {     foreach (datarow row in table.rows)     {         foreach (datacolumn col in table.columns)         {             console.writeline("{0} = {1}", col.columnname, row[col]);         }         console.writeline("-------------------------------------------");     } } }

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
