I want to open command prompt and auto send multiple commands as arguments on button click from windows form application in C#. Here instead of single command I want to send multiple commands one by one to same command prompt. Thanks in advance.

Solution 1

Assuming that your application supports reading the commands from the standard input, just use Process.StandardInput.WriteLine[^] to "send" new commands.

You won't be able to wait for exit though - that only occurs when the command processor exits, and you can't do anything useful with it after that.

If what you are trying to do is "queue up" windows commands to be executed one after the other, then consider writing a .BAT file and executing that instead. The batch file can check for success / fail and optionally continue or fail if you need it to.

1) I tried with using Process.StandardInput.WriteLine[] but it doesn't work here to send command to cmd.exe.
2) Using .bat file make application use restricted as i need to specify specific path of .bat file if it changes then application will fail and even if use getpath in C# to auto search file path, but it won't be able to search where acess is denied.

Write the batch file anew each time with your application, and then execute it. When it completes, delete it. It doesn't have to have a "sensible" name - a GUID.BAT would do if you are worried about the file name conflicting.

Read what I said:
"Assuming that your application supports reading the commands from the standard input, just use Process.StandardInput.WriteLine[^] to "send" new commands."

If you want to queue them up, a batch file is your best solution.

You are kidding, right?
You know how to write files! :laugh:

Thanks for suggestions.I created file using FileStream and added commands with streamwriter. Now code works fine.
