Can you try to remove txtFilename and use hardcoded paths? It could be your path is not correct. A same for psFilename.

Is txtFilename a string variable or textbox control? If it's textbox control then you should use "txtFilename.Text".

It could also be that that postscript file is not valid or buggy. You can check it out by trying to open it via GSView (

You can also use this code to trap Ghostscript errors:
        public class GsStdio : GhostscriptStdIO
            public GsStdio() : base(true, true, true) { }

            public override void StdIn(out string input, int count)
                input = string.Empty;

            public override void StdOut(string output)
                System.Diagnostics.Debug.WriteLine("GS out: " + output);

            public override void StdError(string error)
                System.Diagnostics.Debug.WriteLine("GS err: " + error);
and then instead of
processor.StartProcessing(switches.ToArray(), null);
processor.StartProcessing(switches.ToArray(), new GsStdio());

josip thanks for your quick replay.

i follow your suggest ,use the file path not parameter

i find it work.

the failure reason is the ps file name contains some chinese language ,such as my ps flle name ( Microsoft Word - 辅助办公系统 )

the gsstdio out is
GS out: Error: /undefinedfilename
GS out:  in (C:\\SharePrinter\\Temp\\20140509\\Microsoft Word - \350\276\205\345\212\251\345\212\236\345\205\254\347\263\273\347\273\237
GS out: 2014)
GS out:

Current allocation mode is local

GS err: GPL Ghostscript 
i want to know ,the ps file can not cotains chinese language such as
Microsoft Word - 辅助办公系统
how to resolve this problem?

thanks very much.
