c# - StreamWriter add an extra \r in the end of the line -

i created class responsibility generate text file each line represents information of object of 'mydataclass' class. below simplification of code:

public class generator {     private readonly stream _stream;     private readonly streamwriter _streamwriter;     private readonly list<mydataclass> _items;      public generator(stream stream)     {         _stream = stream;         _streamwriter = new streamwriter(_stream, encoding.getencoding("iso-8859-1"));     }      public void generate()     {         foreach (var item in _items)         {             var line = anotherclass.getlinefrom(item);              _streamwriter.writeline(line);         }          _streamwriter.flush();         _stream.position = 0;     } } 

and call class this:

using (var file = new filestream("name", filemode.openorcreate, fileaccess.readwrite)) {     new generator(file).generate(); } 

when run application on visual studio (i test run (ctrl+f5), debug (f5), debug , release mode) goes according plan. publish application in iis server , streamwriter class put \r before end of line.

check out hexadecimal reading of both generated files:

running in visual studio: http://www.jonataspiazzi.xpg.com.br/hex_vs.bmp

running in iis: http://www.jonataspiazzi.xpg.com.br/hex_iis.bmp

some things checked:

write line variable (in var line = anotherclass.getlinefrom(item);) in log see if '\r' uncluded class anotherclass.

didn't result in nothing, last char in line regular char expected (in example above space).

write code see if problem general iis streamwriter instances.

i tried this:

var ms = new memorystream(); var sw = new streamwriter(ms, encoding.getencoding("iso-8859-1"));  sw.writeline("test"); sw.writeline("of"); sw.writeline("lines");  sw.flush(); ms.position = 0; 

in case code works both visual studio , iis.

i'm in 3 days, try brain can think. did have clue can try?

update

get weirder! try replace line _streamwriter.writeline(line); with:

_streamwriter.write(linhatexto + environment.newline); 

and worse:

_streamwriter.write(linhatexto + "\r\n"); 

both keep generating \r character.

i try replace this:

_streamwriter.write(linhatexto + "#\r\n#"); 

and get:

my guess \r added during ftp (maybe try binary transfer)

like here

i've tested code , /r not due code in current question
