c# - Encode a string with accents and money symbols and returns a FileStreamReturn(MemoryStream) MVC -


i have code:

stringbuilder output = new stringbuilder();  output.appendline("saldo disposición: 23.15€");  [...]  system.text.unicodeencoding en = new unicodeencoding(); byte[] bytearray = en.getbytes(output.tostring()); memorystream stream = new memorystream(bytearray); string filename = guid.newguid().tostring("n").toupper() + ".csv";  stream.flush(); stream.seek(0, seekorigin.begin); return new filestreamresult(stream, "application/vnd.ms-excel") { filedownloadname = filename};

when open document symbol "€" , accent in "disposión" don't appears. seems that:

saldo disposici�n: 23.15�

does tell me how this?

thank you!!

the following works me:

string filename = guid.newguid().tostring("n").toupper() + ".csv";  memorystream stream = new memorystream();  streamwriter output = new streamwriter(stream, encoding.utf8, 2 << 22); output.writeline("column1,column2"); output.writeline("value column one,\"saldo disposición: 23.15€\""); output.writeline("another row col 1,another row col 2"); output.flush();  stream.seek(0, seekorigin.begin);  return new filestreamresult(stream, "application/octet-stream") { filedownloadname = filename };

seems encoding.
