How do i send arguments from C# windows form to GDB console? -

i'm trying make app tests buffer overflow through c# windows form. that, need open gdb c# process , pass following commands:

• cd c:\users\user\desktop
• file file.exe
• disas main
• run file
• insert input

the following code start gdb.exe, unfortunately not change working directory.

process p = new process(); p.startinfo.filename = "gdb.exe";  p.startinfo.arguments = @"cd c:\users\andrei\desktop"; p.start(); 

the gdb console output looks like:

cd: no such file or directory. c:\users\andrei\desktop: permission denied. 

so, have 3 problems now:

• how make change working path?
• how send other commands arguments?
• how console output c# in label/textbox?

thank you.
