C# 中运行exe程序

 private int runProcess(string fileName, string appParam)

        {

            int returnValue = -1;

            try

            {

                Process myProcess = new Process();

                ProcessStartInfo myProcessStartInfo = new ProcessStartInfo(fileName, appParam);

                myProcessStartInfo.CreateNoWindow = true;

                myProcessStartInfo.WindowStyle = ProcessWindowStyle.Hidden;

                myProcess.StartInfo = myProcessStartInfo;

                myProcess.Start();



                while (!myProcess.HasExited)

                {

                    myProcess.WaitForExit();

                }



                returnValue = myProcess.ExitCode;

                myProcess.Dispose();

                myProcess.Close();



            }

            catch (Exception ex)

            {

                MessageBox.Show(ex.Message.ToString());

            }

            return returnValue;

        }

 1、启动*.exe程序

 
　　System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();

    startInfo.Arguments = String.Format("{0}  {1}  {2}", columnStr, tempFilePath, "True");

    startInfo.FileName = this.applicationPath + "\\Excel.exe";

    startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;

    System.Diagnostics.Process process = new System.Diagnostics.Process();

    process.StartInfo = startInfo; 
　　 process.Start(); 　　 
　　 process.WaitForExit();

    process.Close();

 2、调用外部程序

        private void CallOutProcess(string s文件名)

        {

            System.Diagnostics.ProcessStartInfo pinfo = new System.Diagnostics.ProcessStartInfo();

            pinfo.UseShellExecute = true;

            pinfo.FileName = s文件名;

            //启动进程

            System.Diagnostics.Process p = System.Diagnostics.Process.Start(pinfo);

        }
