apache pig - Start pig grunt shell and execute commands using c# -

i working on achieving execution of commands on pig grunt shell using c#. able start grunt shell through c# programme using next code:

proc = new process {startinfo = new processstartinfo { filename = pig_bin + "\\pig.cmd", useshellexecute = false, redirectstandarderror = true , redirectstandardoutput = true, redirectstandardinput = true, createnowindow = true } };

i read output , error through next methods , events:

proc.outputdatareceived += proc_outputdatareceived; proc.beginoutputreadline(); proc.errordatareceived += proc_errordatareceived; proc.beginerrorreadline();

but, unable read output line grunt shell. but, lines before "grunt>" lone read.

i pass arguments grunt shell through next command,

proc.standardinput.writeline("dump a;");

i not able pass arguments grunt shell too. java process started when start grunt shell. if end java.exe in command prompt, "outputdatareceived " event nail , "grunt>" obtained.

i hope grunt running java process , hence not able pass , receive arguments , it. there way accomplish it??
