programmatically executing command line c#

[MedIt]

Hi,
I am using .net Process class to run an executable process , say abc.exe which takes three parameters- two input files(file1 & file2)
and one output file(file3).Bas ed on the two input files, the o/p file3 is to be updated.
The command line on the console will look like this:
C:\dir\...> abc.exe file1 file2 -o file3

On my c# code, I am doing something like:

Process myProc = new Process();
myProc.StartInf o.Filename = "dir\abc.ex e";
myProc.StartInf o.Arguments = "file1, file2, file3";
myProc.Start();

It executes without giving any errors, but my o/p file3 is not updated.
I am trying to figure out where I might have gone wrong to run this process.
Or is there any other way to execute programatically the exe file?
Please help!
Thanks!

If your program is launched like this:

C:\dir\...> abc.exe file1 file2 -o file3

Why are you doing this:

myProc.StartInfo.Filename = "dir\abc.exe";
myProc.StartInfo.Arguments = "file1, file2, file3";

Shouldn't you be doing this?

myProc.StartInfo.Filename = "dir\abc.exe";
myProc.StartInfo.Arguments = "file1 file2 -o file3";

myProc.StartInfo.Arguments = "file1 file2 -o file3";

Sorry, thats my mistake:
in my code it is actually:
myProc.StartInf o.Arguments = "file1 file2 -o file3"

Still no effect!

What if you put:

myProc.StartInfo.Arguments = @"file1 file2 -o c:\file3";

Does the file at c:\file3 get created? It might be making that file somewhere other then where you think it should?
