process.StartInfo.CreateNoWindow = false;

process.StartInfo.CreateNoWindow = false;   这个参数是什么意思，我设置为true也没有什么改变

        public Process ProcessStart(string fileName, string command=null)

        {

            try

            {

                Process process = new Process();

                process.StartInfo.FileName = fileName;

                process.StartInfo.Arguments = command;

                process.StartInfo.UseShellExecute = false;

                process.StartInfo.RedirectStandardInput = true;

                process.StartInfo.RedirectStandardOutput = true;

                process.StartInfo.RedirectStandardError = true;

                process.StartInfo.CreateNoWindow = false;

                process.Start();

                return process;

            }

            catch (Exception ex)

            {

                throw (ex);

            }

        }
