Exec imagemagick convert via c #

When I open a command window in windows and use the imagemagick convert command:

convert / somedir / Garden.jpg / somedir / Garden.png

Works as expected.

What I am trying to do is execute the same command as above using C #.

I tried using System.Diagnostics.Process, however foo.png is not generated.

I am using this code:

      var proc = new Process
      {
          StartInfo =
          {
              Arguments = string.Format("{0}Garden.jpg {1}Garden.png",
              TEST_FILE_DIR,
              TEST_FILE_DIR),
              FileName = @"C:\xampp\ImageMagick-6.5.4-Q16\convert",
              UseShellExecute = false,
              CreateNoWindow = true,
              RedirectStandardOutput = false,
              RedirectStandardError = false
          }
      };

      proc.Start();

      

        
        
        
      

    

No exception is thrown, but a .png is written as well.
