C# GhostScript - Not able to successfully convert from PDF to TXT file

I have been successful with extracting text from a PDF file using GhostScript along with the following command line arguments:

gswin32c.exe ^
  -q -dNODISPLAY -dSAFER -dDELAYBIND ^
  -dWRITESYSTEMDICT ^
  -dSIMPLE ^
  -c save ^
  -f ps2ascii.ps ^
   "test.pdf" ^
  -c quit ^
  >"test.txt"

Points to note: I copied the following three files from the installation directory into my C:\ directory.

1)gsdll32.dll
2)gsdll32.lib
3)gswin32

When manually running GhostScript through the command line I do the following: Run > CMD > cd C:\ (then proceed to input the above arguments).

(The above command works and a new file named "test.txt" appears in my C:\ drive with the appropriate pdf data).

When attempting to execute GhostScript through the command line, however, I am not successful.

In my C# Winform Application, I am using the following code to execute GhostScript:

Process p1 = new Process();
p1.StartInfo.FileName = @"C:\test.exe";
                    p1.StartInfo.UseShellExecute = fa开发者_运维技巧lse;

                    p1.StartInfo.WorkingDirectory = @"C:\";
                    p1.StartInfo.Arguments = " -q -dNODISPLAY -dSAFER -dDELAYBIND -dWRITESYSTEMDICT -dSIMPLE -c save -f ps2ascii.ps " + quote + @"C:\h.pdf" + quote + " -c quit >" + quote + @"C:\test.txt" + quote;
                    File.WriteAllText(@"C:\hhh.txt", p1.StartInfo.Arguments);
                    p1.Start();

Does anyone see any obvious errors with my code? I would appreciate any help I can get here.

Thanks,

Evan

1. Make a batch file named batch.bat as follows.

   rem batch.bat
   rem %1 represents input file name without extension.
   echo off
   gswin32c -q -dNODISPLAY -dSAFER -dDELAYBIND -dWRITESYSTEMDICT -dSIMPLE -c save -f ps2ascii.ps %1.pdf -c quit >%1.txt
   

2. Compile the following code to get a console application named myapp.exe

   using System.Diagnostics;
   
   class myapp
   {
       public static void Main()
       {
           Process p1 = new Process();
           p1.StartInfo.FileName = "batch.bat";
           p1.StartInfo.Arguments = "test";
           p1.StartInfo.UseShellExecute = false;
   
           p1.Start();
           p1.WaitForExit();
        }
    }
   

3. Put all in the same directory as follows and double click the myapp.exe. Done!
