请教的Process.Start()问题

Question

                Process p = new Process();
                p.StartInfo.FileName = @"E:\Development\Fugoo Device\Develop\Fugoo V1.1\Fugoo.Device\Output\Data\MoreStore\DownloadFolder\Youtube_1.0.0.msi";
                System.Threading.Thread.Sleep(3000);
                p.StartInfo.UseShellExecute = false;
                p.StartInfo.RedirectStandardInput = true;
                p.StartInfo.RedirectStandardOutput = true;
                p.StartInfo.RedirectStandardError = true;
                p.StartInfo.CreateNoWindow = true;
                p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
                p.Start();
                p.StandardOutput.ReadToEnd();
                p.WaitForExit(); 
                p.Close(); 程序执行到p.Start()后就出现异常，如果把执行的是一个exe文件就不会报错，为什么呢？请各位帮帮忙，谢谢

Answer 1

不能直接调用，要间接调用http://topic.csdn.net/u/20071012/01/fe3f6356-c231-4bdd-9d5e-065711e0164d.html?849544465

Answer 2

直接调用默认执行程序是explorer.exe
你要用给msiexec.exe传参执行msi文件

Answer 3

不知道是Process的问题还是MSI需要参数，先试试下面这个        [DllImport("shell32.dll", EntryPoint = "ShellExecute")]
        public static extern int ShellExecute(
            int hwnd,
            string lpOperation,
            string lpFile,
            string lpParameters,
            string lpDirectory,
            int nShowCmd
        );

        private void StartInstall(string fileName)
        {
            try
            {
                Process p = new Process();
                string file = fileName;
                p.StartInfo.FileName = "msiexec.exe";
                p.StartInfo.Arguments = string.Format(" /i {0} /passive ", file);
                System.Threading.Thread.Sleep(3000);
                p.StartInfo.UseShellExecute = false;
                p.StartInfo.RedirectStandardInput = true;
                p.StartInfo.RedirectStandardOutput = true;
                p.StartInfo.RedirectStandardError = true;
                p.StartInfo.CreateNoWindow = true;
                p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
                p.Start();
                p.StandardOutput.ReadToEnd();
                p.WaitForExit();
                p.Close();             }
            catch(Exception ex)
            {
                Fugoo.Themes.Controls.Dialogs.MessageBox.Show(ex.ToString());
            }
        }fileName 实际就是E:\Development\Fugoo Device\Develop\Fugoo V1.1\Fugoo.Device\Output\Data\MoreStore\DownloadFolder\Youtube_1.0.0.msi但是这样根本就没有执行E:\Development\Fugoo Device\Develop\Fugoo V1.1\Fugoo.Device\Output\Data\MoreStore\DownloadFolder\Youtube_1.0.0.msi这个文件，请问各位高手，谢谢了

具体怎么传呢？
private void StartInstall(string fileName)
  {
  try
  {
  Process p = new Process();
  string file = fileName;
  p.StartInfo.FileName = "msiexec.exe";
  p.StartInfo.Arguments = file;
  System.Threading.Thread.Sleep(3000);
  p.StartInfo.UseShellExecute = false;
  p.StartInfo.RedirectStandardInput = true;
  p.StartInfo.RedirectStandardOutput = true;
  p.StartInfo.RedirectStandardError = true;
  p.StartInfo.CreateNoWindow = true;
  p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
  p.Start();
  p.StandardOutput.ReadToEnd();
  p.WaitForExit();
  p.Close();    }
  catch(Exception ex)
  {
  Fugoo.Themes.Controls.Dialogs.MessageBox.Show(ex.ToString());
  }
  }
参数fileName实际就是E:\Development\Fugoo Device\Develop\Fugoo V1.1\Fugoo.Device\Output\Data\MoreStore\DownloadFolder\Youtube_1.0.0.msi文件，
我这样不会执行E:\Development\Fugoo Device\Develop\Fugoo V1.1\Fugoo.Device\Output\Data\MoreStore\DownloadFolder\Youtube_1.0.0.msi
请问该如何做？谢谢
