How do I launch a subprocess in C# with an argv? (Or convert agrv to a legal arg string)
- by lucas
I have a C# command-line application that I need to run in windows and under mono in unix. At some point I want to launch a subprocess given a set of arbitrary paramaters passed in via the command line. For instance:
Usage: mycommandline [-args] -- [arbitrary program]
Unfortunately, System.Diagnostics.ProcessStartInfo only takes a string for args. This is a problem for commands such as:
./my_commandline myarg1 myarg2 -- grep "a b c" foo.txt
In this case argv looks like :
argv = {"my_commandline", "myarg1", "myarg2", "--", "grep", "a b c", "foo.txt"}
Note that the quotes around "a b c" are stripped by the shell so if I simply concatenate the arguments in order to create the arg string for ProcessStartInfo I get:
args = "my_commandline myarg1 myarg2 -- grep a b c foo.txt"
Which is not what I want.
Is there a simple way to either pass an argv to subprocess launch under C# OR to convert an arbitrary argv into a string which is legal for windows and linux shell?
Any help would be greatly appreciated.
