Why can not decode persian character from csv file with c#? -

i'm write code read csv file:

var reader = new streamreader(file.openread(@"c:\test.csv"));     list<string> lista = new list<string>();     list<string> listb = new list<string>();     while (!reader.endofstream)     {         var line = reader.readline();         var values = line.split(';');          lista.add(values[0]);         listb.add(values[1]);     } 

, sample csv file recode here:

استان نمونه عمليات دوره صورت حساب- دوره اول سال 1393    1393,01,01  1393,03,01`enter code here` 

when debug program,i data sample line:

��� ���� �������,��� ������ 

happen?why can see data csv file? when open file visual studio see this:

if has done once, easiest way open csv file , convert unicode text. open csv file in visual studio , following:

choose file -> advanced save options -> choose 'unicode (utf-8 signature) - codepage 65001' -> save file , try again.

according msdn, stream reader should able pick correct encoding.

the streamreader object attempts detect encoding looking @ first 3 bytes of stream. automatically recognizes utf-8, little-endian unicode, , big-endian unicode text if file starts appropriate byte order marks.

edit:

change code to:

var reader = new streamreader(file.openread(@"c:\test.csv"), encoding.getencoding(1256));
