Pass arguments from c# to a Console Application

I am trying to pass arguments to a Console Application from C#. The console application works when I pass the argument from the command line like this:
EnterInfo.exe 37 img05.png

//37 is the Record ID and img05.png is the image that I am moving to another folder and entering the information in a database

Open in new window


The code that I am using in c# that does not call the Console Application is:
                            //Call Console Application
                            ProcessStartInfo startInfo = new ProcessStartInfo();
                            startInfo.FileName = @"C:\inetpub\wwwroot\SportsData\EnterInfo.exe";
                            startInfo.Arguments = FileID + fileName;
                            Process.Start(startInfo);

Open in new window

The arguments do have values because I am able to display them on the page

What response are you getting from your call to the console, if any?

Try passing your parameters with a space between them.
i.e.
startInfo.Arguments = FileID + " " + fileName;

I am not getting a response from the call to the console. I tried your suggestion and the executable does not run. This is the first time that I am calling a console application from a web page. Is there an error log that I can create? How do I debug something like this?

I have no idea with respect to the web portion aspects of the question, but sometimes a working directory must also be set for a process to work correctly:
            startInfo.FileName = @"C:\inetpub\wwwroot\SportsData\EnterInfo.exe";
            startInfo.WorkingDirectory = System.IO.Path.GetDirectoryName(startInfo.FileName);

I created a script that gives me an error message when running the console application

I get this error:

Unhandled Exception: System.IndexOutOfRangeException: Index was outside the bounds of the array. at EnterInfo.Program.Main(String[] args)

So I am assuming that the arguments are not passing correctly to the Console Application. It gives line number 26 as the error and line 26 is this in Program.cs:

            string ID = args[0];  //Line 26
            string fileRequestName = args[1];  //Line 27

            string FileID = "37";
            string fileName = "img05.png;

            //Call Console Application
            ProcessStartInfo startInfo = new ProcessStartInfo();
            startInfo.FileName = @"C:\inetpub\wwwroot\SportsData\EnterInfo.exe";
            startInfo.Arguments = FileID + " " + fileName;
            startInfo.UseShellExecute = false;
            startInfo.CreateNoWindow = true;
            startInfo.RedirectStandardError = true;
            startInfo.RedirectStandardOutput = true;
            using (var process = Process.Start(startInfo))
                    {
                        string message;

                        using (var reader = process.StandardOutput)
                        {
                            message = reader.ReadToEnd();
                            label1.Text = message;
                        }

                        if (!string.IsNullOrEmpty(message))
                        {
                            label1.Text = message;
                        }
                        else
                        {
                            using (var reader = process.StandardError)
                            {
                               label1.Text = reader.ReadToEnd();
                            }
                        }
                    }

I think I may know what the problem is when I run the console application when the web page says open, it works fine. However when I close the web page after I start the application it dos not work. So is there a way I can start the application and then close the web page?
