options for shelling out command line commands

[djc]

I'm wondering what options are available, if any, for being able to run 'any
command line command' from a .net compiled program. I would want the output
that would normally go to the command line for the command to be available
to my program.

I know from even very old VB that you can 'shell' out and run programs, one
of which could be for example, cmd.exe with specific command but I don't
know that you could get the actual command results (other than an exit, or
return code). Plus, before I go 'shelling out' I wanted to see if there is a
'newer' way of doing this. Maybe something more builtin like a class that
actually exposes an interface to send standard shell commands to and returns
the results to you in code? The actual output that would appear on the
screen if you had run the command from the command line.

eg.
myVariable = SomeCoolClass.E xecShellCmd("di r c:")

and the directory listing for c: would be a string in myVariable (including
white space chars to preserve formatting)

anyone know of anything like this? Buitlin to .net already?

Hello djc,

The only way is to redirect output of the console program to file and read
result afterwards

Use the "RedirectStanda rdOut" property. See:

You don't have to redirect to a file. When using the Process class,
you can redirect the output of the console program to a stream and then
just read that stream to get the output from the program.

[djc]

thats one way I was thinking could work. That or creating an environment
variable to redirect to and subsequently retrieve from.

thanks for the reply.

[djc]

that sounds perfect! Thanks.

are you refering to the same class as Patrick Steele is in his reply to this
post?
System.Diagnost ics.Process AND System.Diagnost ics.ProcessStar tInfo?

I'll check this out tomorrow, I just wanted to clarify these are the same
solution and not 2 different ones.
