New Post: How to deal with the error stream when using ShellStream

thanks, i will try your codes .
the reason why not using RunCommand it that when i test running "nohup" command or a script containing "nohup" command and the command is finished,the program is disappeared.so i need a shell.
about "Thread.Sleep(200)".when i remove the stop,the output sometimes runs wrong. so i try to find some examples in the discussion area, and then i find some codes like this.
