Module could not be loaded

[litao198610]

when i use ghostscript.net to print pdf file,the system throw exception "Module could not be loaded",I downloaded gsdll to a local folder，Do you know what caused it? the code is following:
public static void Printpdf(string pdfFilePath,string printerName)
{
try
{
var path = "";
if (Environment.Is64BitOperatingSystem)
{
path = Path.Combine(AppContext.BaseDirectory, "GSDll/gsdll64.dll");
}
else
{
path = Path.Combine(AppContext.BaseDirectory, "GSDll/gsdll32.dll");
}
var gvi = new GhostscriptVersionInfo(path);
Ghostscript.NET.Processor.GhostscriptProcessor processor = new Ghostscript.NET.Processor.GhostscriptProcessor(gvi, true);
var switches = new List();
switches.Add("-empty");
switches.Add("-dPrinted");
switches.Add("-dBATCH");
switches.Add("-dNOPAUSE");
switches.Add("-dNOSAFER");
switches.Add("-dNoCancel");
switches.Add("-dNOPROMPT");
switches.Add("-dNOPAGEPROMPT");
switches.Add("-dPDFFitPage");
switches.Add("-dQueryUser=3");
switches.Add("-dNumCopies=1");
switches.Add("-dSubsetFonts=false");
switches.Add("-sDEVICE=mswinpr2");
switches.Add("-f");
switches.Add(Convert.ToString("-sOutputFile=%printer%") + printerName);
switches.Add(pdfFilePath);
processor.StartProcessing(switches.ToArray(), null);
}
catch (Exception ex)
{
if (System.IO.File.Exists(pdfFilePath)) { System.IO.File.Delete(pdfFilePath); }
throw new Exception(ex.Message,ex);
}
}

I have seen this error when gsdll64.dll from ghostscript native library installation got somehow corrupted. LoadLibrary Win32 function was returning error 998 ERROR_NOACCESS. Overwriting the file with fresh copy resolved the issue.
