一个打印pdf的小程序,在本机上运行一切正常,但是复制到其他机器上就会报错 ,错误信息如下
System.ComponentModel.Win32Exception: 没有应用程序与此操作的指定文件有关联。
   在 System.Diagnostics.Process.StartWithShellExecuteEx(ProcessStartInfo startI
nfo)
   在 System.Diagnostics.Process.Start()
   在 Print.Print.PrintDoc(String filename) 位置 行39..源代码如下:
public void PrintDoc(string filename)
        {
            //检测当前打印的文档数,当超过2个,就开始等待  
           PrintDocument pd = new PrintDocument();
           StringCollection sc = GetPrintJobsCollection(pd.PrinterSettings.PrinterName);
           while (sc.Count > 2)
           {
              Thread.Sleep(1000);
                sc = GetPrintJobsCollection(pd.PrinterSettings.PrinterName);
            }
            try
            {
                Process processInstance = new Process();
                ProcessStartInfo startInfo = new ProcessStartInfo();
                startInfo.UseShellExecute = true;
                startInfo.Verb = "Print";
                startInfo.CreateNoWindow = true;
                startInfo.WindowStyle = ProcessWindowStyle.Minimized;
                startInfo.FileName = filename;
                processInstance.StartInfo = startInfo;
                processInstance.Start();
            }
            catch(Exception e)
            {
                Console.Write(e.ToString());
            }
        }请高人解释是什么原因!
