How To Run PERL Scripts In C#

Question

_{Monday, March 30, 2009 12:46 PM}

Hi

I am currently writing an application in C# and I need it to call a PERL script to do some text processing. I have searched on a number of different forums and found some code which people have said should work but when I use it, the file is not processed.

The code I have is:

ProcessStartInfo perlStartInfo = new ProcessStartInfo("perl.exe");
perlStartInfo.Arguments = "Word_Splitter.pl " + inputFilePath + " > " + outputFilePath;
perlStartInfo.UseShellExecute = false;
perlStartInfo.RedirectStandardOutput = true;
perlStartInfo.RedirectStandardError = true;
perlStartInfo.CreateNoWindow = true;

Process perl = new Process();
perl.StartInfo = perlStartInfo;
perl.Start();
string output = perl.StandardOutput.ReadToEnd();
perl.WaitForExit();

I have tried playing around with the different settings in an attempt to get it to work but so far I have had no luck. I would appreciate any help anyone could give me on this.

The PERL script that I am attempting to run can be found here:

Thanks in advance

This is working for me

ProcessStartInfo perlStartInfo = new ProcessStartInfo(@"d:\Perl\bin\perl.exe");
            perlStartInfo.Arguments = "c:\word-splitter.pl " + "c:\a.txt" + " ispell";
            perlStartInfo.UseShellExecute = false;
            perlStartInfo.RedirectStandardOutput = true;
            perlStartInfo.RedirectStandardError = true;
            perlStartInfo.CreateNoWindow = false;

            Process perl = new Process();
            perl.StartInfo = perlStartInfo;
            perl.Start();
            perl.WaitForExit();
            string output = perl.StandardOutput.ReadToEnd();Thanks, A.m.a.L [Remember to click "mark as answered" when you get a correct reply to your question]

Thanks Again

I did the same thing as told.My perl script is very simple just printing Hello World. I use the output to be appeared in a text box but it doesn't print anything. I also debug the code the see the value in output  but it appears to be null. Can you please help me?

Seems like a coding issue.

Post the code you are working on.

I am trying to run just a simple PERL script without any output. What differences would I need to make to the above code, if i don't have any output?

Could you post your entire c# file(s)?
