how to use String[] args when using re-direction (">>") in c#?

Question

I have a program test.exe that receives arguments and writes some logs in a specific .txt path that I give as an input. I wanted to add this command:

text.exe /r >> textFile.txt 

meaning : build the project and write the logs to the textFile.txt (that doesn't exist) I'm not sure how it works? is args[2] = ">>" and args[3] = textFile.txt ? how can I use the name of it?? confused!

editing : when I'm debugging and looking at the locals I see only /r but the >> textFile.txt doesn't appear at all. how can I get it fro the command line as a pararmeter?

edit2 :

Understood that it should re-direct automatically, but when I'm doing it it just fails and sends me to a line : Console.CursorLeft = 0; meaning i'm trying to do somethong with the cursor when I don't have a console... just .txt

thanks!

No, the command shell will only pass /r to test.exe, and it will automatically redirect output to append to textFile.txt. Your app doesn't get to see that - at least not simply.

If you just make your program write to the standard output (e.g. with Console.WriteLine) that output will end up in textFile.txt.
