unicode - Another Encoding/Decoding in C# Issue -

i've been working on gui cli. rather write text file, i'm redirecting standard output, , creating abject output can use/reuse within gui code. have tried every possible solution have come across, , have yet resolve issue. it's each line in return encoded in 2 different ways. here have command line interface:

class cmdtoolinteraction {      private static string returnstring = null;      public string runcommandline(string argumentstring)     {         unicodeencoding uni = new unicodeencoding();         process proc;         proc = new process();         proc.startinfo.filename = "cmd.exe";         proc.startinfo.arguments = argumentstring;          proc.startinfo.windowstyle = processwindowstyle.hidden;          proc.startinfo.useshellexecute = false;          proc.startinfo.redirectstandardoutput = true;          proc.startinfo.redirectstandardinput = true;          proc.start();          streamwriter cmdstreamwriter = proc.standardinput;         cmdstreamwriter.write(argumentstring);         cmdstreamwriter.close();         returnstring = uni.getstring(proc.standardoutput.currentencoding.getbytes(proc.standardoutput.readtoendasync().result));          proc.waitforexit();          console.write(returnstring);         return returnstring;      } } 

where i'm running issue output. of readable english white rest jibberish/chinese i.e.

"someone@somewhere.net਍  䰀愀渀最甀愀最攀㨀 攀渀ഀ\n success਍ഀ"

in instances entire line or return looks second half of above when know there should english alphanumerics instead.

halp!

edit:

i updated code above add proc.startinfo.standardoutputencoding = encuding.unicode

i still string "someone@somewhere.net਍  䰀愀渀最甀愀最攀㨀 攀渀ഀ\n success਍ഀ" know why now. second part in case in bigendian unicode, whereas rest littleendian. i'm trying figure out how clean uninterpreted parts.

edit #2 @ roelands suggestion took unicode output , tried convert ascii. similar issue feel i'm getting closer "someone@somewhere.net਍  䰀愀渀最甀愀最攀㨀 攀渀ഀ\n success਍ഀ" reads "someone@somewhere.net???????????????\n success??"

i have decoding set this:

byte[] bytes = encoding.ascii.getbytes(proc.standardoutput.readtoend()); returnstring = encoding.ascii.getstring(bytes); 

i think it's indeed encoding issue. list of bytes (part of string), assuming string utf-16 little endian. closely @ bytes around newline:

119 'w'   0 104 'h'   0 101 'e'   0 114 'r'   0 101 'e'   0  46 '.'   0 110 'n'   0 101 'e'   0 116 't'   0  13 cr  10 lf   0  32 ' '   0  32 ' '   0  76 'l'   0  97 'a'   0 110 'n'   0 103 'g'   0 117 'u'   0 

at point utf-16 byte stream interpreted ansi text, , newlines ("\n") expanded cr-lf pairs, corrupting utf-16 string.

the solution depends on how program works. need run program via cmd command processor? if so, use /u option? otherwise, can open i/o streams in binary mode?
